Stability of Ionogels upon Contact with Water: Effect of Polymer Matrix Hydrophobicity and Ionic Liquid Solubility

New composite materials (ionogels) have been obtained based on imidazolium ionic liquids immobilized in highly porous polymers, i.e., polyamide 6,6 (nylon 6,6) and low-density polyethylene. A method has been proposed for determining the rate of ionic liquid removal from an ionogel upon contact with water, with this method being based on continuous measuring the conductivity of an aqueous phase. The results of the conductometric measurements have been confirmed by high-performance liquid chromatography data. It has been shown that the stability of ionogels upon contact with water is determined by both the hydrophobicity of a polymer matrix and the solubility of an ionic liquid in water. The highest degree of ionic liquid removal (more than 80%) has been observed for composites based on porous polyamide 6,6 (hydrophilic matrix) and dicyanimide 1-butyl-3-methylimidazolium (completely miscible with water). Ionogels based on lowdensity polyethylene (hydrophobic matrix) and bis(trifluoromethylsulfonyl)imide 1-butyl-3-methylimidazolium (poorly soluble, 1 wt %, in water) have shown the highest stability (washout degree of no more than 53% over 24 h). The method proposed for analyzing the rate of ionic liquid dissolution in water has been used to discuss the mechanism of this process.

Feasibility of coal bottom ash as fine aggregate in strain-hardening cementitious composites: A study on strength, durability, and sustainability

The search for cost-effective and sustainable materials for strain-hardening cementitious composites (SHCC) has led researchers to explore alternatives to silica sand, a critical yet costly and environmentally unfavorable material. Although river sand seems like a cheaper and viable alternative, its extraction is linked to severe environmental degradation. This study aims to investigate the potential of coal bottom ash (CBA) as a replacement for silica sand in SHCC, targeting to meet the minimum requirements for structural applications. The novelty of this research lies in its comprehensive exploration of CBA as a partial to full replacement for silica sand (at 0 %, 25 %, 50 %, 75 %, and 100 %), extending beyond the replacement limit investigated in previous studies on SHCC, and provides an extensive evaluation of the composite’s fresh, mechanical, durability, and microstructural properties. Additionally, it includes a thorough assessment of the leaching potential, CO₂ emissions, energy consumption, and cost implications of the CBA-SHCC, which have not been fully explored in earlier CBA-SHCC research. The findings indicate that the reduction in mechanical strength was minimal (0.5 %-10 %) across all CBA replacement levels. Notably, all mixes demonstrated typical strain-hardening behavior, sustaining higher flexural loads beyond the first crack, with increased deflection capacity observed at higher CBA contents, peaking at 50 % replacement. Durability metrics, including water absorption and HCl acid attack resistance, exhibited a downward trend with higher CBA content but remained within acceptable limits up to 75 % replacement. Toxicity characteristic leaching procedure results confirmed the non-leachability of toxic elements in both the CBA and CBA-SHCC mixes. Economically and environmentally, CBA proved advantageous, resulting in 1.5–5 % lower CO2 emissions, 0.4–1.5 % lower energy consumption, and 18–84 % cost savings at 25–100 % CBA replacement. Additionally, a multicriteria analysis using the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) was employed, which identified 25 % as the optimal CBA content that balances fresh properties, mechanical strength, durability, environmental sustainability, and cost efficiency. The study is significant because it demonstrated that CBA can be used as a sustainable and cost-effective alternative to silica sand in SHCC, with lower environmental impact while maintaining structural integrity.

Revealing multi-level shortrange migration of electrons on full-spectrum response e-LDH/t-BiOCl/Bi2S3 and their essential role in the detoxification of Cr(VI) and refractory organic pollutants

The toxic dyeing wastewater containing both carcinogenic Cr(VI) and refractory dyes poses serious threats to ecological safety and human health. Herein, a novel composite photocatalytic material e-LDH/t-BiOCl/Bi2S3 with an ultrathin sandwich structure constructed achieves removal rate constants of 0.044 and 0.019 min−1 for Cr(VI) and reactive red 2 by adsorption-photocatalysis synergistic mechanism in full-spectrum illumination. This structure employs the interface conditions and built-in electric field to form multilevel short-range charge migration channel, achieving the targeted reduction and oxidation of Cr(VI) and azoxy dyes by electrons (e−) and holes (h+). Besides facilitating the reduction of Cr(VI), e− can also enhance the effective utilization of h+ and mediate the formation of other reactive oxygen species that target RR2 degradation. The degradation mechanism, pathway, and biological toxicity of RR2 single and Cr(VI)/RR2 coexistence reaction system were discussed by DFT calculation, LC-MS characterization, and T.E.S.T. evaluation. Moreover, we further investigated the photocatalytic activity and cost-effectiveness of the e-LDH/t-BiOCl/Bi2S3 system under continuous flow and real water settings, and determined the primary water quality parameters that influence photocatalytic performance. This work establishes a new concept for the rational design of robust ternary heterostructure photocatalysts with desirable morphology and competitive performance for photocatalytic applications.

Encapsulating phase change materials into melamine formaldehyde sponge assembled with polypyrrole modified halloysite nanotube for effective solar-thermal energy storage and solar-thermal-electric conversion

Exploiting inexpensive composite phase change materials (PCMs) with comprehensive characteristics of high encapsulation efficiency, good leakage resistance, strong flexibility, high heat conductivity, and powerful light absorption is considerably imperative for their solar-thermal and solar-thermal-electric conversion. Herein, polypyrrole (PPy) modified halloysite (HNT/PPy) was assembled into the pores of melamine formaldehyde (MF) sponge to construct hierarchical porous structure (MHP), in which PPy serves as light absorber and heat conducting agent to consolidate the light absorption and thermal conductivity, while the interwoven HNT in MF not only acts as carrier to provide sufficient space for guaranteeing more PCMs’ encapsulation, but also dramatically narrows MF’s pore size and prevents PCMs’ leakage. As expected, the MHP can encapsulate as high as 95 wt% of polyethylene glycol (PEG) with extremely high latent heat of 177.8 J g−1 (PEG@MHP). The rich hydroxyl groups on PEG, PVA and HNT form strong hydrogen bond interaction, effectively improving the leakage-proof performance of PEG@MHP. Especially, PEG@MHP with 82 wt% encapsulation ratio (PEG@MHP-82) demonstrates unexceptionable leakage resistance (negligible leakage at 100 °C), strong light absorption (97 %), good photothermal conversion efficiency (90.36 %), and high thermal conductivity (0.235 W m−1 K−1). Except that, the solar-thermal-electric (STE) conversion system assembled with PEG@MHP-82 enables efficient voltage and current outputs of 587 mV and 83.3 mA respectively under 3 kW m−2 with heat dissipation in water. Encouragingly, the voltage output still achieves 154.7 mV under actual outdoor illumination (0.984 kW m−2). This work provides a simple method to efficiently encapsulate PCMs for realizing high-efficiency solar-thermal and solar-thermal-electric conversion.

Preparation of high oxygen vacancies catalyst CeO2/Al2O3-SiC and its mechanism in enhancing the catalytic ozonation of organic pollutants in coal chemical wastewater

The complete harmless treatment of aromatic organic compounds in coal chemical wastewater (CCW) has always been a big challenge in water process engineering. This study addresses the issue by designing and preparing a kind of Ce and Al bimetallic catalyst with high oxygen vacancies (OVs) based on SiC carrier. The results showed that CeO2 and Al2O3 were uniformly dispersed on SiC, and the composite material exhibited an ordered cubic structure. The degradation efficiency and enhancement mechanism of the catalyst with ozone oxidation were investigated. When applied to actual CCW with a chemical oxygen demand (COD) concentration exceeding 600 mg/L, the synergy between O3 and CeO2/Al2O3-SiC increased the degradation efficiency of phenols from 50 % to 99 % and COD from 42 % to 78 % compared to using O3 alone. CeO2/Al2O3-SiC had a high concentration of oxygen vacancies (OVs = 48.57 %). Further research indicated that oxygen vacancies (OVs) were the main active sites for ozone adsorption and reactive oxygen species (ROSs) generation. Electron paramagnetic resonance (EPR) and quenching experiments also confirmed that O3, •O2−1, 1O2 were the main active oxidation factors, rather than •OH. Additionally, even after granulating the catalyst, it still achieved 99 % degradation of phenols. Therefore, this study provides theoretical support for the complete harmless treatment of CCW and has broad prospects for industrial application.

Feasibility of Recovering and Recycling Polymer Composites from End-of-Life Marine Renewable Energy Structures: A Review

Over the last few decades, several marine renewable energy (MRE) technologies, such as wave energy converters (WECs) and current energy converters (CECs), have been developed. As opposed to traditional materials such as metal alloys, the structure of these technologies is made up of polymer and polymer composite materials. Most structures have been made using thermoset polymer composites; however, since thermoset polymer composites are not recyclable and lack sustainability, and with recent innovations in recyclable resins, bio-based resins, and the development of additive manufacturing technologies, thermoplastic polymers are increasingly being used. Nevertheless, the methodologies for identifying end-of-life options and recovering these polymer composites, as well as the recycling and reuse processes for MRE structures, are not well-studied. Specifically, since these MRE structures are subjected to salinity, moisture, varying temperature, biofouling, and corrosion effects depending on their usage, the recyclability after seawater aging and degradation needs to be explored. Hence, this review provides an in-depth review of polymer composites used in marine applications, the hygrothermal aging studies conducted so far to understand the degradation of these materials, and the reuse and recycling methodologies for end-of-life MRE structures, with a particular emphasis on sustainability.

The Role of Micro Propulsion in Enabling Autonomous Operations of Nanosatellites

Micro-Electro-Mechanical Systems (MEMS)-based propulsion devices have significant potential for providing high specific power. The application of Micro Power Generation technology to space propulsion systems can enhance orbit and station-keeping capabilities, potentially at lower costs. New-generation spacecraft and satellites are becoming smaller and require micro-propulsion systems for all aspects of their operations. The development of micro-propulsion systems with associated combustors for micro-electricity generation, utilizing liquid fuel, presents major challenges in fuel injection, mixing, combustion, and chemical reactor systems. A micro-spacecraft with high-accuracy station-keeping and attitude control capabilities needs to have low mass and deliver small impulses. Each nanosatellite will weigh a maximum of 10 kg, including the propellant mass. Provisions for orbital manoeuvres, attitude control, multiple sensors, and instruments, along with full autonomy, will result in a highly capable miniaturized satellite. All onboard electronics will endure a total radiation dose of 100 k rads over a two-year mission lifetime. Nanosatellites designed for in-situ measurements will be spin-stabilized and equipped with a complement of particles and fields instruments. Nanosatellites intended for remote measurements will be three-axis stabilized and equipped with imaging and radio wave instruments. Key technologies under development include: advanced, miniaturized chemical propulsion systems; miniaturized sensors; highly integrated, compact electronics; autonomous onboard and ground operations; miniaturized onboard orbit determination methods; onboard RF communications capable of transmitting data to Earth from significant distances; lightweight and efficient solar array panels; lightweight, high-output battery cells; a miniaturized heat transport system; lightweight yet strong composite materials for nano-satellite and deployer-ship structures; and simple, reusable ground systems.

Promising antibacterial performance of Ag-nanoparticles intercalated Nb2CTx MXene towards E. coli and S. aureus

MXenes are a group of two-dimensional (2D), atomically thin transition metal carbides, nitrides and carbon nitrides with a variety of desirable characteristics. Due to their exceptional physiochemical characteristics and ultrathin lamellar structure, MXenes have shown excellent antibacterial capabilities. Two-dimensional Nb2CTx MXene has been recently analyzed for potential applications in antibacterial materials. Due to the development of antibiotic-resistant bacteria further materials or composite materials need to be explored. In this work, we report the antibacterial properties of a composite of Nb2CTx and silver, synthesized using electrostatic self-assembly method. This work also demonstrates the optimization of the etching of Nb2CTx MXene for different time intervals and delamination of Nb2CTx MXene by using two different solvents i.e., tetramethylammonium hydroxide (TMAOH) and isopropyl amine. The antibacterial characteristics of Nb2CTx MXene, delaminated Nb2CTx MXene and Nb2CTx-Ag composite of 1:1 and 2:1 were tested and compared. This study demonstrates that Nb2CTx-Ag composite shows higher antibacterial properties than Nb2CTx and delaminated Nb2CTx MXene and could reach an antibacterial activity of 98.5 % for S. aureus and 100 % for E. coli.

Ranking Analysis of Tribological, Mechanical, and Thermal Properties of Nano Hydroxyapatite Filled Dental Restorative Composite Materials Using the R‐Method

ABSTRACTR‐method as multi criteria decision‐making method was proposed to determine the ranking of alternatives and performance criteria or attributes of dental composite materials. Five alternatives (DHM0, DHM2, DHM4, DHM6, and DHM8: nomenclatures of micro‐nano ceramic particulate filled dental restoration composites) and 14 attributes (performance criteria) were considered in this research. The decision‐maker determined the relevance of each rank and then attributed it to the performance criterion. In a similar manner, the options were ranked in relation to each performance criterion according to the associated performance criteria. Therefore, the order of the ranks of dental composites is DHM8 (1st rank) > DHM4 (2nd rank) > DHM6 (3rd rank) > DHM0 (4th rank) > DHM2 (5th rank). The suggested technique is showed simpler and advance compared to the other generally employed decision‐making techniques.

Patterning Composites Made of Rodlike and Bent-Core Molecules for Electric Applications.

Soft materials are ideal candidates for creating tunable, self-assembled architectures. Composite materials are elaborately designed with an unusual physical performance that combines solid nanostructures and orientationally ordered soft matter. Such composites can not only inherit properties of their constituents but also exhibit excellent conductivity. Herein, we demonstrate a dewetting method to pattern binary mixtures composed of rod-like (R) 8OCB and bent-core (BC) OXD-7 molecules. By confining the R-BC composite in a geometric sandwich system with a surface-modified surface, we were able to generate R-BC microstripes that were not only nearly uniform in size but also highly ordered in alignment. It was found that these composite microstripes formed donor-acceptor systems that enhance the conductivity of the soft system while not altering the coexisting smectic phase of 8OCB and B6 phase of OXD-7.

Investigation of wear and transverse rupture strength of AA2219/ZrO2/B4C hybrid composite materials prepared with 3D ball mixer and produced by spark plasma sintering

ABSTRACT Aluminum alloys have advanced to meet the growing demand for strong, lightweight materials. The 2219 aluminum alloy has gained popularity due to its superior mechanical properties and high copper content. However, despite these improvements, the wear characteristics of metal matrix composites with ceramic reinforcements have been suboptimal. This study aims to develop metal matrix composites that improve the mechanical and wear properties of AA2219 aluminum alloy. A homogeneous mixture was created using a 3D mechanical mixer/miller apparatus. ZrO2 and B4C reinforcements were added to the matrix in ratios of 5%, 10%, and 15%, including hybrid composites with both reinforcements. Mechanical and wear characteristics were analyzed, and a 3D profilometer was used to evaluate wear properties and determine tribological parameters. The results showed that the pulverized reinforcement particles were uniformly dispersed within the matrix. The sample with a hybrid reinforcement comprising 15% of the total composition exhibited the highest hardness, measuring 164.96 hV. This study demonstrates that incorporating ceramic reinforcements in specific ratios can significantly enhance the mechanical and wear properties of 2219 aluminum alloy composites.

Research on the Performance of Carbon Fiber Composite Railings for Ships

With the development of the shipbuilding industry, the requirements for the safety and corrosion resistance of ship structural components are becoming increasingly high. Most of the components used in traditional ships are made of steel, which cannot meet the requirements of corrosion resistance and safety for existing ships. In order to improve the structural safety and corrosion resistance of ship railings, as well as their lightweight requirements, this article proposes a lightweight design for ship railing structures based on the advantages of carbon fiber composite materials, such as light weight, high strength, and high modulus, on the basis of the existing traditional metal railing structures for ships. Based on the anisotropy of carbon fiber composite fibers, the characteristics of overlapping/weaving structures, and the influence of the interface between carbon fiber composite materials and metal materials on the strength of ship railing structures, a finite element simulation model of carbon fiber composite materials is established. By setting constraints such as volume fraction, stress, strain, displacement,etc.in the given simulation model, the layout of materials in the optimization results is used to guide the design of the structure, and the size parameters of the ship railing barrel are optimized for structural optimization. Thus achieving lightweight design of ship railings and meeting the requirements for lightweight, safety, service life, and corrosion resistance of ship structural components.

Preparation and Experimental Study of Corrosion-induced Shape-memory Fibers for Crack Repair

Repairing concrete cracks is crucial for enhancing the safety and durability of concrete structures. However, current repair technologies face limitations in corrosive environments such as marine settings. This study presents a novel corrosion-induced shape-memory fiber (CSF) based on the concept of corrosion-induced intelligent fiber (CIF). The CSF1 was made by coating elongated spandex-covered yarn with polyvinyl alcohol, and the CSF2 was prepared by winding stretched nylon fiber with iron wire. Experimental results demonstrate that CSF1 specimens can rapidly heal a 10mm wide crack within two seconds when exposed to water, while CSF2 specimens exhibit obvious shape recovery when exposed to seawater. Moreover, under midspan loads, pre-cracked CSF2-acrylic plate specimens achieve effective crack closure in seawater. These findings confirm the successful transfer of prestress from CSFs to the matrix, thereby validating the feasibility of CIF-based crack repair theory. This research provides experimental evidence for designing and optimizing self-repairing composite materials tailored for various corrosive environments and engineering applications.

Development of polymeric composite scaffolds for defective bone repair and regeneration

Bones are vital components of the body that provide soft internal organs and tissues with structure, motion, and safety. Damage to bones can make life challenging. In repairing and regenerating damaged bone, polymeric composite materials significantly contribute to bone tissue engineering. In this article, we described developing porous scaffolds using the freeze-drying process from sodium alginate (SA), polyvinyl alcohol (PVA), and graphene oxide (GO) incorporated with zinc (Zn). These scaffolds were characterized by Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM), and universal testing machine (UTM) to investigate their structural analysis, surface morphology, and mechanical behavior, respectively. These scaffolds also exhibited less swelling in phosphate buffer saline (34.73–64.27%) than in aqueous media (42.36–75.92%) with controlled degradation. These scaffolds have potential biomineralization activities, hemocompatibility, and antibacterial activities, which were increased by increasing the Zn amount. All the scaffolds have biocompatibility as they have shown cell viability with mature cell morphology against preosteoblast and HEK-293 cell lines under standard in vitro conditions. The enhanced biological activities of the scaffolds were found by increasing the Zn amount. Thus, newly designed polymeric composite scaffolds would be promising materials to repair and regenerate fractured bone tissue.

Natural zeolite/PVC beads for the removal of ammonium ions from water: Wettability, particle size, strength, hydrophilicity and equilibrium behaviour

This study developed an improved method for removing ammonium ions from water using natural zeolite/PVC beads. Research gaps relating to the impact of particle size, wettability, robustness, hydrophobicity and equilibrium behaviour were addressed. It was surmised that manipulation of the formation of natural zeolite/PVC beads will improve the performance of these composite materials. First it was noted that water-saturated sorbents exhibited higher ammonium ion exchange rates than dried beads. An air nozzle was proposed as a potential solution for controlling particle size. To control bead particle size, a range of airflow rates passed through an optimised 3D printed nozzle design. Bead diameters from below 0.5 mm up to 2 mm were obtained, with higher airflow rates promoting the growth of smaller beads. 0.5–1 mm beads also were characterised by lower attrition rates compared to larger ≈ 2.7 mm particles (54 to 57 % change) and had almost the same kinetics exchange rate as their regular unbound zeolite powder counterparts (0.4 to 13.5 % difference). The equilibrium data was in the shape of a linear isotherm, which suggested that the ammonium ions were equally dispersed throughout the sorbent and the aqueous solution. Finally, the use of amphipathic copolymer (Pluronic F127) improved the exchange kinetics of the dry beads (42 to 160 % change) but also weakened the structural integrity of the zeolite composites (284 to 647 % change depending on the analysed composites).

The thermal behavior of silicone-based composite materials and the assessment of the gases that result from the thermal degradation process

A series of composite materials were prepared on the basis of polydimethylsiloxane (PDMS) having different siloxane functionality, filled with two types of metal complexes containing siloxane segment, derived from condensation of 1,3-bis(3-aminopropyl)tetramethyldisiloxane with 3,5-di-tert-butyl-2-hydroxibenzaldehyde and 5-chloro-2-hydroxibenzaldehyde. The main objective of the proposed study is to introduce transition metal complexes with Schiff-base ligands that contain siloxane spacers into the PDMS matrix and examine the effect these complexes have on thermal stability. We investigated the produced gases using thermogravimetry coupled with FTIR and MS in order to analyze the thermal stability and degradation pathways of a variety of silicone composite materials.

Synergetic effect driven LaMnO3@NiO composite based high energy semi-solid supercapacitor

Perovskite materials have gained substantial attention in last two decades as electrode materials for energy storage devices due to low cost, good electrochemical stability, mixed ionic-electronic conductivity, long-term stability, and environmentally friendly. We demonstrate the hybridization of lanthanum manganite (LaMnO3) and Nickel oxide (NiO) composite electrodes for supercapacitor application prepared via sol-gel assisted hydrothermal method. The structural, morphological, surface area, and elemental analysis has been done by X-ray diffraction, Field emission scanning electron microscopy, Brunauer-Emmett-Teller (BET), and X-ray photoelectron spectroscopy (XPS) analysis. The structural, and morphological analysis confirmed the composite formation. The electrochemical properties have been examined by cyclic voltammetry, galvanostatic charge-discharge, and impedance analysis. The resulting LaMnO3/NiO composite material exhibits enhanced electrochemical performance compared to the individual components. The composite exhibits a specific capacitance of up to 170 F/g at a scan rate of 10 mV/s, which is higher than that of individual LaMnO3 or NiO materials. The composite also demonstrates desirable cycling stability, with a capacity retention of 76 % after 5000 cycles. These results advocate that the LaMnO3/NiO composite is a promising material for high-energy supercapacitor applications. Further performance of the nano-composite was evaluated by LED testing. Three symmetric SCs of the composite linked in series were able to glow a green, red, blue LED for about 1 min and a panel of 26 red LED was illuminated for about 12 min. These findings suggested that the obtained composite material is an exceptional electrode with huge potential for potential for supercapacitor application.

Novel fabrication of polyethylene glycol/ceramic composite pellets with an excellent phase change shape stable trait and their potential applications for greenhouse insulation

Organic solid–liquid phase change materials (PCMs) face challenges in practical applications due to their susceptibility to leakage during phase transitions. To address this issue, we constructed the polyethylene glycol (PEG)/ceramic pellets (CPs) composite phase change shape stable materials (PCSHs) with thermal energy storage capability, thermal stability, and a firm texture using the melting impregnation method. The PCSHs exhibit remarkable shape stability in the leakage test due to the capillary action and surface tension generated by the micropore structure on their surface. They also can convert light energy into heat and store it as latent heat, achieving an optimal photothermal conversion efficiency of 45.21 % and a maximum melting enthalpy of 13.33 kJ/kg at a PEG loading of ∼ 12 %. An outdoor greenhouse insulation simulation experiment confirmed that the PCSHs can maintain soil temperatures above 30 °C for over 30 min after illumination ceases. This work presents a facile synthesis strategy for shape-stable PCMs with potential applications in greenhouse insulation.

Amino-acid surface modulation of cobalt-tin sulfide and band broadening in cobalt-iron selenide heterostructure for high-performing asymmetric supercapacitor

Controlled synthesis of hierarchical flowerlike cobalt tin sulfide (SnCoSx) is successfully obtained using the chelation of the biomolecule l-asparagine with cobalt-tin metal cations by a hydrothermal technique. l-asparagine plays a crucial role as an inducer and a good structure-directing activity. Subsequently, pine needle-shaped cobalt iron selenium (FeCoSey) is tightly deposited on the SnCoSx surface to construct cobalt tin sulfide coated with cobalt iron selenide (FeCoSey@SnCoSx) heterostructure, which has exposed more active sites and the most abundant channels for electron/ion transfer. Among all prepared electrodes, the optimized FeCoSey@SnCoSx demonstrates the highest energy storage capacity (1754.65 F/g at 1 A g−1) and excellent cycling steadiness (86.71 % after 10,000 cycles at 15 A g−1). The heterogeneous interface engineering of FeCoSey and SnCoSx enables the FeCoSey@SnCoSx composite to generate outstanding electrochemical performance for supercapacitor devices. As expected, an asymmetric hybrid supercapacitor (AHSC) based on FeCoSey@SnCoSx cathode and nitrogen-doped hierarchy porous activated carbon (NHPC) derived from soybeans anode displays a high energy density of 59.44 Wh kg−1 at 402.09 W kg−1 and a super-long steady presentation with a preliminary capacitance holding ratio of 92.2 % following 10,000 cycles with an 8 A g−1 voltage density. This strategy provides a new approach for the controllable preparation of electrode material morphology, opens up new methods for high-performance heterogeneous interface composite electrode materials, and guides the designing of low-cost energy storage devices.
