Due to the high theoretical capacity values and versatile valence states, the molybdenum incorporated mixed metal sulfides ((Mox-Mn)Sy) nanoparticles decorated over 2D Ti3C2 sheets are reported for Li-ion battery and asymmetric supercapacitor. A uniquely designed (Mox-Mn)Sy-NPs@MXene hybrid material displays a high Li-ion storage capacity of up to 698 mA h g−1 at 50 mA g−1, and a commendable areal capacity performance (∼1.27 mA h cm−2 at 2 mA cm−2) for supercapacitor, along with outstanding capacity retention at higher current density and stable cycling performance. Furthermore, a 0D@2D (Mo-Fe7)Sx-NPs@MXene hybrid material is utilized as anode material to construct a coin cell-like (Mox-Mn)Sy-NPs@MXene//(Mo-Fe7)Sx-NPs@MXene asymmetric supercapacitor (ASC) device.

Defect-induced electron rich nanodomains in CoSe0.5S1.5/GA realize fast ion migration kinetics as sodium-ion capacitor anode

Optimizing charge migration and alleviating volume expansion in anode materials are the key to improve the electrochemical performance for sodium-ion storage devices. Herein, a hierarchical porous conducting matrix confining defect-rich selenium doped cobalt dichalcogenide (CoSe0.5S1.5/GA) is constructed as a promising SICs anode based on the guidance of theoretical calculation analysis. The increased defect concentration significantly enhanced the disorder degree of the compound and presented electron aggregation around the S atoms, which effectively modulated the electronic structure, further enabling high rate and ultra-capacity sodium storage. Moreover, strong interfacial coupling could construct spatial constraint to alleviate volume expansion as well as maintain electrode integrity and stability. The CoSe0.5S1.5/GA electrode can deliver a high capacity of 310.1 mA h g−1 after 2000 cycles at 1 A g−1, and the CoSe0.5S1.5/GA//AC sodium ion capacitor can exhibit an outstanding energy density of 237.5 W h kg−1. A series of characterization and theoretical calculation convincingly reveal that the defect moieties can regulate the Na+ storage and diffusion kinetics, which prove that our defect manufacture coupling with space-confined strategy can provide deep insights into the development of high-performance Na+ storage devices.

Unveiling the structure-activity relationship of hollow spindle-like α-Fe2O3 nanoparticles via phosphorus doping engineering for enhanced lithium storage

The low-cost earth-abundant transition metal oxides (TMOs) reveal high-capacity as post‑carbon anodes towards Li-ion batteries (LIBs), however, their intrinsically low electroconductivity, sluggish Li-ion diffusion and undesirably large volume change during cycles, strictly hamper their practical applications. Doping heteroatoms and designing hollow structures is a facile strategy in improving electronic/ionic conductivity and buffering volume expansion, respectively. Herein, a design strategy of inner-outer phosphorus (P) doped hollow spindle-like α-Fe2O3 nanoparticles (NPs), is introduced, where hollow spindle-like α-Fe2O3 NPs endure volume change during Li-ion (de-)intercalation process while inner-outer P-doping induced phase transition of Fe2O3-to-Fe3O4 causes P-Fe3O4/Fe2O3 heterojunction to improve the ionic/electronic conductivity and Li-ion active sites owing to abundant oxygen vacancies. Significantly, calcination temperatures determined the P contents, where increasing temperature from 300 °C (1 wt% P) to 500 °C (29 wt% P) exhibits the emergence and disappearance of P-Fe3O4/Fe2O3 heterojunctions and the transition of hollow-to-solid structures, which thus improves and attenuates their electrochemical performances, electronic/ionic conductivity and reaction kinetics. Notably, 10 wt% P doped Fe2O3 (350 °C) anode exhibits the remarkable rate capacity and cycle stability. This work thus deciphers the structure-activity relationship of electrode materials and opens a new avenue to enhance the electrochemical performance of energy storage devices.

Intelligent static synchronous compensator with super-capacitor for enhancement of power network security

Power network security becomes an important issue for power system economics. A proportional integral-based static synchronous compensator in flexible AC transmission systems is generally used to enhance power network security. But, it takes more time to make the network stable and secure. A PI-controlled STATCOM with a super-capacitor as an electrical storage device and transient performance improver helps the network become stable and secure. As the PI controller depends on mathematical modeling, it may respond slowly, affecting the stability and security of the network. A fuzzy logic controller, as an intelligent controller with logical rules, can overcome the slow response problem of PI controllers. Hence, to enhance power network security, an intelligent static synchronous compensator in coordination with a super-capacitor is suggested here. A multimachine network is modeled in a MATLAB environment with severe faults near the generator, making it unstable and unsecure. The validation of the proposed combination is observed by comparing the performance of the network without STACOM, with conventional PI STATCOM, with intelligent STATCOM, and with intelligent STATCOM coordinated with a super-capacitor.

Since the industrial revolution, the consumption of fossil fuels has increased year by year, which has resulted in increasing greenhouse gas emissions. Carbon capture, utilization and storage technology has received extensive attention as a technology for converting atmospheric carbon dioxide into high value-added materials. Carbon materials, as ideal materials for various energy storage devices, have attracted extensive research.

In particular, we emphasize the reaction processes during CO2 conversion, which can build an understanding of the science and technology involved in the control of interfacial properties, microstructure, and pore structure of CO2-converted carbon nanomaterials. We also summarized the basic design principles for the application of carbon nanomaterials in the field of energy storage. The effect of the microstructure and interface properties of carbon materials converted from CO2 on the energy storage performance are further analyzed. Finally, prospects and discussions are made on the challenges of future development.

Thermal storage performance of latent heat thermal energy storage device with helical fin under realistic working conditions

Latent heat thermal energy storage has garnered increasing interest and development as a significant technique for recovering waste heat. In this research, the latent heat thermal energy storage device with helical fin is proposed and its thermal storage performance is also investigated by numerical simulation. First, assorted helix pitches (400 mm, 200 mm, 100 mm and 50 mm) and fin numbers are taken into account to investigate the thermal storage performance with various fin parameters. Then, four types of nanoparticles (SiC, TiO2, CuO and Al2O3) are dispersed into the phase change material to address the inherent defect of poor thermal conductivity of phase change material. Afterwards, several realistic working circumstances, including four inclination angles (θ = 0°, 30°, 60° and 90°) and eight oscillating inlet temperatures among which the frequencies are 1 Hz, 2.5 Hz, 5 Hz and 10 Hz, and amplitudes are 0.25, 0.5, 1 and 2, are selected to explore the impact on melting process. The results indicate that shortening helix pitch and increasing fin number can accelerate the melting rate, while the selection of these two parameters needs to consider the thermal storage performance and the processing difficulty as a whole. Furthermore, the selection of nano phase change materials needs to balance the relationship between thermal storage rate and capacity. Compared to the complete melting time when the device is placed vertically, the complete melting time is reduced by 14.3% when the device is placed horizontally. Utilizing the oscillating inlet temperature reduces the complete melting time by at least 21.2% compared to using the steady inlet temperature. When the frequency value is increased from 1 to 10, the complete melting time is only reduced by 3.4%. Complete melting time of the amplitude of 2 is 12.9% shorter than that of the amplitude of 0.25.

Exploring the electrochemical properties of CuSe-decorated NiSe2 nanocubes for battery-supercapacitor hybrid devices

Chalcogenides, a promising class of electrode materials, attracted massive popularity owing to their exciting features of high conductive nature, high capacity, rich redox activities, and structural functionalities, making them the first choice for the electrochemical energy domain. This paper reported a new NiSe2–CuSe nanocomposite prepared via a wet-chemical synthesis followed by a low-cost and simple hydrothermal reaction. The physical characterization showed cubes and nanoparticles type morphological features of NiSe2 and CuSe products, while their composite reveals a combined morphological characteristic. The electrochemical properties were tested in an aqueous solution, demonstrating that the NiSe2–CuSe nanocomposite exhibits a high capacity of 376 C g−1, low resistance, good reversibility and rate capability in a three-electrode mode than bulk counterparts. For practical aspects, a battery-hybrid supercapacitor (BHSC) is developed with NiSe2–CuSe nanocomposite, and activated carbon (AC) serves as cathode and anode in two-cell mode operation. The built NiSe2–CuSe||AC/KOH BHSC expanded the voltage to 1.8 V and delivered the highest capacitance of 148 F g−1 and 55 F g−1 from 1 to 10 A g−1, suppressing most of the previously existing literature reports. Also, our built NiSe2–CuSe||AC/KOH BHSC displayed a high-power delivery of 8928 W kg−1 at a maximum energy density of 66.6 W h kg−1 and retained 91.7% capacitance after a long way of 10,000 cycles. These outstanding results demonstrate that metal selenides can be effectively utilized as alternative electrodes with high energy, rate performance, and long-term durability for advanced energy conversion and storage devices.

The impact of non-ideal phase change properties on phase change thermal energy storage device performance

Phase change materials have been known to improve the performance of energy storage devices by shifting or reducing thermal/electrical loads. While an ideal phase change material is one that undergoes a sharp, reversible phase transition, real phase change materials do not exhibit this behavior and often have one or more non-idealities – glide, hysteresis, supercooling – associated with them. Experimental and modeling techniques to characterize these non-ideal properties are reasonably well understood, however, their impact on the performance of a thermal energy storage system is not fully understood. Here, we analyze the performance of a heat exchanger with a phase change material as a function of the different non-idealities, for a heating and a cooling application. We focus on the impact of these non-ideal behaviors on different modes of operation of the thermal energy storage device, which will serve as a useful guide to researchers on the relative importance of the non-ideal properties, along with the necessary accuracy required during an experimental characterization.

Adaptive Interfacial Contact between Copper Nanoparticles and Triazine Functionalized Graphdiyne Substrate for Improved Lithium/Sodium Storage

AbstractThe high activity of nano‐sized metal particles (NMPs) makes it easy to appear uncontrolled aggregation, which seriously affects Li/Na storage in electrode materials. Introducing adaptive substrates with proper affinity to NMPs is an effective strategy that optimizes the stability and capacity of the related electrodes. Herein, a comprehensive strategy for the fabrication of adaptive interfacial contacts between metallic Cu nanoparticles (NPs) and triphenyl‐substituted triazine graphdiyne (TPTG) substrates is reported. The sp C in the acetylenic linkers and N heteroatoms in the triazine groups synergistically stabilized the Cu NPs loaded onto the TPTG substrates. The stabilizing effect of the TPTG substrate induces a reversible lattice change of the Cu NPs during the charge–discharge process, thus efficiently facilitating the stable transfer of Li+/Na+. Intrinsic mechanism analysis indicates that the heterojunction contact interface of Cu NPs/TPTG provides branched charge transfer pathways from Li/Na to the Cu NPs and TPTG substrates, which synergistically adjusts the affinity to Li/Na atoms and ultimately improves the electrochemical performance in Li/Na storage. The investigation of the structure–property relationship deepens the understanding of the function of heterointerfaces, which is essential for optimizing the performance of energy storage devices.

Morphology Engineering of VS4 Microspheres as High-Performance Cathodes for Hybrid Mg2+/Li+ Batteries.

V-based sulfides are considered as potential cathode materials for Mg2+/Li+ hybrid ion batteries (MLIBs) due to their high theoretical specific capacities, unique crystal structure, and flexible valence adjustability. However, the formation of irreversible polysulfides, poor cycling performance, and severe structural collapse at high current densities impede their further development. Herein, VS4 microspheres with various controllable nanoarchitectures were successfully constructed via a facile solvothermal method by adjusting the amount of hydrochloric acid and were used as cathode materials for MLIBs. The VS4 microsphere self-assembled by bundles of paralleled-nanorods and some intersected-nanorods (VS4@NC-5) exhibits an outstanding initial discharge capacity of 805.4 mAh g-1 at 50 mA g-1 that is maintained at 259.1 mAh g-1 after 70 cycles. Moreover, the VS4@NC-5 cathode can deliver a superior rate capability (146.1 mAh g-1 at 2000 mA g-1) and ultralong cycling life (134.5 mAh g-1 at 2000 mA g-1 after 2000 cycles). The extraordinary electrochemical performance of VS4@NC-5 could be attributed to its special multi-hierarchical microsphere structure and the formation of N-doped carbon layers and V-C bonds, resulting in unobstructed ion diffusion channels, multidimensional electron transfer pathways, and enhancements of electrical conductivity and structure stability. Furthermore, the electrochemical reaction mechanism and phase conversion behavior of the VS4@NC-5 cathode at various states are investigated by a series of ex situ characterization methods. The VS4 well-designed through morphological engineering in this work can pave a way to explore more sulfides with high-rate performance and long cycling stability for energy storage devices.

Graphene Oxide (GO) metal nanocomposites make up an emerging class of advanced materials and enhance material functionality to obtain multifunctional properties and working towards superior performance of energy storage devices. GO was derived from Myanmar coal minerals using Modified Hummer method. The silver and nickel nanoparticles were used as metal ions or metal nanoparticles to form GO nanocomposites. Their characteristics were identified by XRD, SEM and Raman Spectroscopy. The energy gap of GO and GO composites was also investigated by the aid of UV-Vis spectroscopy. The dielectric constant is measures of the amount of electrical energy that can be stored in GO derived from coal mineral. The frequency-dependent dielectric properties and AC conductivity has been explored using GW INSTEK LCR-8110 meter. It was found that the dielectric constant is maximum at low frequencies region and decreases with increasing frequency. The electrochemical performance of this sample was examined by cyclic voltammetry (CV) measurement. The CV curves of GO have typical rectangular-like shape and no evident oxidation/reduction peak. The prototypes of flat-shaped capacitors were prepared and their capacitive values were also determined. The as-prepared GO on the copper foil can be directly used to fabricate solid-state super capacitor.

Enhancing the Performance of Cobalt‐based Oxide Electrode Material for Asymmetric Supercapacitor Devices

AbstractSupercapattery is an energy storage device which shows high power and energy densities compared to supercapacitors and batteries. A simple and cost‐effective sol‐gel method was used to synthesize the aluminium‐doped cobalt oxide (Al‐Co3O4). The structural, morphological and composition analyses were investigated using X‐ray diffraction (XRD), scanning electron microscopy (SEM), and X‐ray photoelectron spectroscopy (XPS). Further, Brunauer‐Emmett‐Teller (BET) calculations were performed, which showed an enhancement in surface area. The specific capacity of the Al‐doped sample was increased up to 708 C/g compared to the reference sample (Co3O4=420 C/g). A supercapattery device was designed by using the activated carbon as a negative electrode and the Al‐Co3O4 as the positive electrode in two electrode assemblies. The estimated value of the specific capacity of Al‐Co3O4 was 189 C/g. Furthermore, the obtained energy and power density values were 42 Wh/kg and 2080 W/kg, respectively. To investigate the stability, this device was subjected to 5000 charging/discharging cycles that maintained 90 % of its initial capacity. Our findings provide a foundation for improving the performance of energy storage devices.

Heat transfer characteristics of fluids containing paraffin core-metallic shell nanoencapsulated phase change materials for advanced thermal energy conversion and storage applications

The influence of heat transfer characteristics of fluids filled with paraffin core-metallic shell nanoencapsulated phase change material (PCM) on photothermal conversion and storage in a volumetrically heated solar system is numerically analysed. The results show that nanoencapsulated paraffin/Al, paraffin/Au, paraffin/Ag, and paraffin/Cu filled heat transfer fluids enhance the energy storage by 68, 73, 92 and 86 %, respectively as compared with the water-based Al, Au, Ag and Cu nanofluids. It is found that the phase change slurry (PCS) improves the temperature and storage gain, as the utilization of nanoencapsulated PCM and the rise in PCM mass concentration enhance the solar energy absorption power of the slurry. The maximum enhancement in stored energy is also observed for paraffin/Cu PCM filled slurry for a particle diameter of 15 nm. The enhancement in mass concentration of paraffin from 5 to 20 %, improves the thermal performance from 312 to 554 % compared to pure water, respectively. Increasing the size of the core/shell architecture of the PCM, however, reduces the surface area-to-volume ratio of the capsule, causing aggregation of the particles and decreasing the heat transfer between the capsule and the host fluid. This in turn results in decrease in temperature gain. Furthermore, it is noticed that the merger of mono- and hybrid- nanoparticles augments the thermal performance of the PCS. The findings of the study indicate that the paraffin core-metallic shell nanoencapsulated PCMs would significantly enhance the performance of advanced photothermal energy conversion and storage devices.

CuCo2O4 supported graphene quantum dots as a new and promising catalyst for methanol oxidation reaction

Recently, the design of an active electrocatalyst with a unitary structure and high electrocatalytic performance as an efficient and low-cost electrode material has received enormous attention in improving the performance of energy and storage devices. In this study, flower-like CuCo2O4 nanorods are synthesized through the hydrothermal method followed by calcination. Then, CuCo2O4 is hybridized with graphene quantum dots (GQDs) prepared by the pyrolysis method. The structure and morphology of the synthesized electrocatalysts are analyzed by scanning electron microscopy, transmission electron microscopy, Raman spectroscopy, Fourier transform infrared spectroscopy, and X-ray diffraction methods. The electrochemical performance of the prepared materials supported on a glassy carbon electrode is investigated by cyclic voltammetry at different methanol concentrations and various scan rates. Also, chronoamperometry and electrochemical impedance spectroscopy techniques are performed for the evaluation of stability and conductivity. The GQD/CuCo2O4 exhibits a good electrochemical surface area of 19.25 cm2 in 1 M KOH and 4 M methanol. Also, GQD/CuCo2O4 shows a higher current density for methanol oxidation reaction (MOR) than CuCo2O4. The superior electrochemical performance of the GQD/CuCo2O4 can be attributed to the strengthening of the CuCo2O4 nanoparticle structure by a large electrochemically active surface associated with nanoporous morphology in the presence of GQDs. Besides, GQDs enhance the catalyst's performance by increasing electrical conductivity and specific surface area.
