Aqueous zinc-organic batteries using organic cathode materials with resourceful and environmental friendliness have attracted much attention for their sustainability and excellent electrochemical performance. And selectively storing H+ in mild aqueous electrolytes by organic active materials can lead to fast reaction kinetics for zinc-organic batteries, thus providing excellent rate performance. Herein, we have synthesized 2,3,7,8-Tetraamino-phenazine (TAPZ) with four π-conjugated amino groups, CN active sites, and extended aromatic planes, including small energy gap values and accessible electrochemically active centers, as well as good electrical conductivity, enables selective storage of H+ in aqueous electrolytes. In the optimized 3 M ZnSO4 electrolyte, TAPZ demonstrates excellent electrochemical properties as a cathode material, including the high initial discharge specific capacity (238.8 mAh g−1 at 100 mA g−1), a good rate capacity (125.4 mAh g-1 at 3 A g-1), and the long cycle stability (over 3000 cycles at 1 A g-1). In addition, the H+ storage mechanism of TAPZ in mild electrolytes is verified by ex-situ spectroscopic characterization and density functional theory (DFT) calculations.

Chemical anchor of lithium polysulfide through sulfur copolymers for high-performance lithium-sulfur batteries

The lithium-sulfur battery has been regarded as a potential candidate for next-generation energy storage and conversion devices due to its high energy density, high theoretical capacity, and low cost of sulfur. However, its practical applications are still restricted by the polysulfide shuttle effect and the low redox kinetics. It has been demonstrated efficiency in ameliorating the polysulfide problem by utilizing the chemical bonds to realize chemical anchor of polysulfides through the design of molecular structures of sulfur copolymers. Herein, a sulfur copolymer is developed by directly copolymerizing sulfur to 2-methylimidazole through a hydrogen abstraction. In this sulfur copolymer, not only the abundant S-N bonds strongly anchored lithium polysulfides, restricting the polysulfide transportation, but also the generated sulfur-contained chemical bonds contribute to the decrease of the lithiation barrier, accelerating the slow redox kinetics. Therefore, this sulfur copolymer reveals a high initial capacity of 952 mAh g−1 at 0.5 C, and a high capacity of 1524 mAh g−1 at 0.1 C and improved rate capacities while composite with carbon nanotubes.

Biopolymer‐assisted Synthesis of P‐doped TiO2 Nanoparticles for High‐performance Lithium‐ion Batteries: A Comprehensive Study

AbstractTiO2 material has gained significant attention for large‐scale energy storage due to its abundant, low‐cost, and environmentally friendly properties, as well as the availability of various nanostructures. Phosphorus doping has been established as an effective technique for improving electronic conductivity and managing the slow ionic diffusion kinetics of TiO2. In this study, non‐doped and phosphorus doped TiO2 materials were synthesized using sodium alginate biopolymer as chelating agent. The prepared materials were evaluated as anode materials for lithium‐ion batteries (LIBs). The electrodes exhibit remarkable electrochemical performance, including a high reversible capacity of 235 mAh g−1 at 0.1 C and excellent first coulombic efficiency of 99 %. An integrated approach, combining operando XRD and ex‐situ XAS, comprehensively investigates the relationship between phosphorus doping, material structure, and electrochemical performance, reinforced by analytical tools and first principles calculations. Furthermore, a full cell was designed using 2 %P‐doped TiO2 anode and LiFePO4 cathode. The output voltage was about 1.6 V with high initial specific capacity of 148 mAh g−1, high rate‐capability of 120 mAh g−1 at 1 C, and high‐capacity retention of 96 % after 1000 cycles at 1 C.

Suppressing shuttle effect of polysulfides by yttrium hydroxide nanoarchitecture for stable lithium‑sulfur batteries

Rechargeable lithium–sulfur (Li–S) batteries reveal promising prospect as high energy storage systems because of the extraordinary theoretical specific energy density. However, the shuttle effect and sluggish reaction kinetics of polysulfides hamper the commercialization applications of high energy density Li-S batteries. Herein, a novel and efficient sulfur host material of yttrium hydroxide (Y(OH)3) has rationally been achieved for Li–S batteries. Y(OH)3 host not only suppress shuttle effect of polysulfides by physical confinement and chemisorption, but also decline Li2S nucleation and deposition reaction barriers and expedite chemical reaction kinetics. Consequently, the prepared Y(OH)3/S cathodes achieve a high initial specific capacity of 1295 mAh g−1 at 0.1 C and improved cycling stability with a low capacity decay rate of 0.019% per cycle over 1000 cycles at 2.0 C. The enhanced performances confirm a potential host material for facilitating practical implementation of Li–S batteries.

Synergistic effect in the ZIF67-derived core shell structure towards the improved electrochemical performances in lithium-sulfur batteries

A ZIF-67 core could be grown within the hollow carbon sphere to further develop the hierarchical core shell structure, which displays synergistic effects as sulfur host in lithium sulfur batteries (LSB). The carbon shell with N active sites exhibits strong anchoring capability towards lithium polysulfide (LiPS), and the electrochemical conversion kinetic is favorably accelerated by the ZIF-67 derived carbon core. By virtue of the unique core shell structure and advantageous active species of the host material, the resulting composite cathode exhibits the high initial reversible capacity of 1308 mAh g−1 at 0.1C and outstanding long-term stability at 2C with a mere 0.039 % decay rate over 600 cycles. This work may shed a light on rational designing of novel sulfur host material towards the synergistic improvement of electrochemical performances of LSB.

Interfacial Synergy in Mo2C/MoC Heterostructure Promoting Sequential Polysulfide Conversion in High-Performance Lithium-Sulfur Battery.

A rational design of sulfur host is the key to conquering the"polysulfide shuttle effects" by accelerating the polysulfide conversion. Since the process involves solid-liquid-solid multistep phase transitions, purposely-engineered heterostructure catalysts with various active regions for catalyzing conversion steps correspondingly are beneficial to promote the overall conversion process. However, the functionalities of the materials surface and interface in heterostructure catalysts remain unclear. In this work, an Mo2C/MoC catalyst with abundant Mo2C surface-interface-MoC surface tri-active-region is developed by in situ converting the MoZn-metal organic framework. The experimental and simulation studies demonstrate the interface can catch long-chain polysulfides and promote their conversion. Instead, the Mo2C and MoC tend to accommodate the short-chain polysulfide and accelerate their conversion and the Li2S dissociation. Benefitting from the high catalytic ability, the Li-S battery assembled with the Mo2C/MoC-S cathode shows more discrete redox reactions and delivers a high initial capacity of 1603.6 mAh g-1 at 1 C charging-discharging rate, which is over twofolds of the one assembled using individual hosts, and 80.4% capacity can be maintained after 1000 cycles at 3 C rate. This work has demonstrated a novel synergy between the interface and material surface, which will help the future design of high-performance Li-S batteries.

Effect of Zr4+ doping on the electrochemical properties of Na3MnTi(PO4)3/C cathode materials

NASICON structural materials have the advantages of structural stability, high ion conductivity, and high working potential, which have attracted widespread attention as cathode for sodium-ion batteries. Although the three-electron reaction in the NASICON structure Na3MnTi(PO4)3 increases the specific capacity of the material, poor electronic conductivity remains a key factor restricting its practical application. Herein, Na3Mn1-xZrxTi(PO4)3/C (x = 0, 0.01, 0.03, 0.05, 0.07 and 0.1), a typical three-dimensional NASICON structure cathode material for sodium-ion batteries, was synthesized by the sol-gel method. Through powder X-ray diffraction, the Zr4+ doping in the Na3MnTi(PO4)3 (NMTP) structure was verified. It was found that doping trace amounts of Zr at the Mn site can not only reduce the Jahn-Teller effect caused by Mn3+, but also strengthen the Zr-O bond compared to the Mn-O bond, making the crystal structure more stable by reducing the proportion of Mn. According to the findings of the EIS test, a suitable amount of Zr doping can enhance the electronic conductivity and Na ion diffusion coefficient of NMTP/C electrode materials, weaken polarization phenomena, increase electrode reaction rate, and significantly improve the rate performance and cycling performance of Na3Mn1-xZrxTi(PO4)3 material. The Na3Mn1-xZrxTi(PO4)3/C sample prepared has high initial capacity of 124mAh/g, a capacity retention rate of 86 % after 200 cycles at 0.2C, and a capacity retention rate of 84 % after 500 cycles at 1C. This proves that the material still exhibits excellent cycling stability and structural stability after high current cycling. More importantly, the Na3Mn0.95Zr0.05Ti(PO4)3 (Zr5-NMTP)//Hard carbon full battery also exhibits ideal electrochemical performance.

Li2O–V2O5–MoO3–Fe2O3 amorphous cathode material for lithium-ion batteries based on coordinated multi-electron effect and stable network structure

The amorphous cathode materials Li2O–V2O5–MoO3 and Li2O–V2O5–MoO3–Fe2O3 were produced via melt quenching. By analyzing the structure, elemental valence, and electrochemical characteristics of Li2O–V2O5–MoO3 at different ratios, the effects of MoO3 addition on vanadium-based amorphous cathode materials were explored. 20Li2O–60V2O5–20MoO3 has a high initial capacity (268.0 mAh/g for the first reversible discharge at a current density of 50 mA/g), which is based on the properties that MoO3 supplies additional oxidation reductions and has [MoO6] structural units to widen the diffusion channels for lithium ions in the network structure. Unfortunately, the network of the structural elements [MoO6] and [VO4] is unstable, which causes the material to have poor cycle stability and exhibit an unsatisfactory current response. The network structure stability of Li2O–V2O5–MoO3–Fe2O3 is increased by adding Fe2O3 to provide [FeO4], which strengthens the link between each structural unit. Vanadium oxidation reductions are promoted, and iron oxidation reductions replace the role of molybdenum in the charge/discharge. The discharge product transforms from LiVMoO5 to Li2FeV3O8 with increased de-embedding Li efficiency. The 20Li2O–60V2O5–10MoO3–10Fe2O3 achieves an initial reversible specific capacity of 255.2 mAh/g at 50 mA/g, 139.7 mAh/g additional specific capacity after 100 cycles, and 110.5 mAh/g specific capacity at a high current density of 400 mA/g. The test findings show that 20Li2O–60V2O5–10MoO3–10Fe2O3 efficiently increases high-current responsiveness and cycle stability while retaining a high capacity. In this study, we propose a compositional design strategy, which is based on the coordinated multi-electronic effect of multiple transition metal elements and the design of a stable disordered network structure, to incorporate MoO3 and Fe2O3 into vanadium-based amorphous to create a novel cathode material. This work offers a fresh perspective on investigating innovative lithium-ion battery cathode materials.

Carbons Derived from Agave tequilana Fibers as Efficient Sulfur Supports for High‐Performance Lithium–Sulfur Batteries

The fabrication of cathodes with carbonized Agave tequilana bagasse for Li–S batteries is performed for the first time. Three porous carbonaceous structures are developed and studied to elucidate the best carbon textural properties in terms of their surface area and pore size distribution: hierarchical porosity, highly microporous, and nonporous material, for sulfur hosting in Li–S cathodes. N2 physorption, scanning electron microscopy, infrared spectroscopy, and potentiometric titrations analysis are performed to determine the textural, morphology, and physicochemical properties. The fabricated coin cells, CR2032, with cathodes made of mesoporous carbons, display a high discharge current (≈1600 mAh g−1), superior performance, and cyclability up to 250 cycles. The performance of batteries is found to be strongly influenced by surface area and pore size of the carbon materials. The carbonized tequila bagasse hosting sulfur can be very useful to fabricate cathodes for Li–S batteries with high initial capacity and cycling stability.

CoS2-MoS2-CNT composite modified separator with enhanced LiPS adsorption capacity for lithium-sulfur battery

The three-dimensional mesh CoS2-MoS2-CNT composite material with abundant pores was prepared by two-step hydrothermal method as CoS2-MoS2-CNT functional separator and introduced into lithium-sulfur battery. XRD, XPS and SEM tests of CoS2-MoS2-CNT proved that the material was successfully prepared, and its morphology was a three-position porous structure composed of interwoven nanotubes and nanosheets. The results of Li2S6 adsorption experiment and visual penetration experiment show that CoS2-MoS2-CNT composite material has strong adsorption effect on LiPS, and can prevent LiPS from passing through the separator, which effectively inhibits the shuttle effect. CoS2-MoS2-CNT coating effectively plays the synergistic effect of each component to achieve effective fixation and transformation of LiPS, which solves the shortage of lithium-sulfur batteries. Cells with CoS2-MoS2-CNT functional separators have a high initial specific capacity (0.2C, 1411 mAh g−1), excellent rate performance and excellent cycle stability at large currents (0.13% attenuation per cycle at 2C).

Carbon nanofibers implanted porous catalytic metal oxide design as efficient bifunctional electrode host material for lithium-sulfur battery

The shuttling effect of lithium polysulfides (LiPSs) and uncontrolled dendrite formation of metal lithium anode are the two critical obstacles hindering the commercial application of lithium-sulfur (Li-S) batteries. Herein, a bifunctional electrode host design consists of carbon nanofibers implanted ordered porous Co-decorated Al2O3 supported on carbon nanotube film (CNTF) is proposed to address these problems. As cathode sulfur host material, benefiting from the synergistic effect of porous Co-Al2O3 and the embedded CNFs, the CNFs/Co-Al2O3@CNTF exhibits excellent conductivity, efficient LiPSs confinement and catalytic conversion performance. It shows a high initial capacity of 1165 mAh g−1 at 0.2 C, and holds a capacity of 594 mAh g−1 even up to 3 C. When serves as anode, the CNFs/Co-Al2O3@CNTF electrode exhibits excellent Li+ diffusion performance and uniform lithium growth behavior, achieving a dendrite-free lithium electrode. The anode also shows good cycle stability during an ultra-long cycle time of 1000 h. A flexible pack cell assembled from CNFs/Co-Al2O3@CNTF electrodes delivers a specific capacity of 972 mAh g−1 with capacity retention rate of 86.4% at 0.1 C.

Polyaniline-coated S/Super-P composites as cathode materials for high performance lithium-sulfur batteries

Lithium-sulfur (Li-S) batteries are promising alternatives to conventional lithium-ion batteries owing to their high theoretical capacity and eco-friendliness. However, their commercialization has been limited due to poor cathode conductivity and polysulfide dissolution. In this study, we synthesized a S/Super-P @ Polyaniline (S/Super-P @ PANi) composite via a straightforward high-energy ball milling (HEBM) and in-situ oxidative polymerization process. The refined sulfur and Super-P particles were encapsulated by a conductive PANi coating shell, which not only facilitated electron transfer but also inhibited the dissolution of lithium polysulfides through physical confinement and chemical adsorption. The S/Super-P @ PANi electrode showed a high initial capacity of 1185.3 mAh·g−1 at 0.1 C. Under a sulfur loading of 3.5 mg·cm−2, the electrode delivered an areal capacity of 2.8 mAh cm−2 and maintained 1.8 mAh cm−2 after 400 cycles, with a capacity decay rate of 0.08% at 0.5 C. This rational and scalable synthesis method has great potential for use in high-performance Li-S batteries.

A ZIF-8 modified aramid nanofiber separator against the shuttle effect for high performance lithium-sulfur batteries

Lithium-sulfur (Li-S) batteries are considered the most promising energy storage systems due to their high specific capacity and energy density. However, the practical application of lithium-sulfur batteries has been hampered by capacity loss due to the shuttle effect and serious safety issues due to the flammability and shrinkage of commercial diaphragms at high temperatures. Herein, we designed a separator by adding ZIF-8 nanoparticles to aramid nanofibers named ZIF-8/ANF. ANF has high flame retardant property and high mechanical strength to prevent separators failure at high temperature, preventing lithium dendrites from punctured separators and causing short circuit. ZIF-8 has the porous structure, while exposing abundant metal nodes acting as active sites, which can effectively adsorb polysulfides and inhibit the shuttle effect. As a result, the Li-S batteries with ZIF-8/ANF separators exhibit high specific discharge capacity and cycle performance. The Li-S batteries show a high initial specific capacity of 1178.3 mAh g−1 at 0.1 C and 525.9 mAh g−1 after 400 cycles. In addition, they also exhibit discharge capacity is 825.6 mAh g−1 at 0.2 C with the loading of 3.5 mg cm−2. This work offers a guidance for safe and high-performance Li-S batteries.

Preparation of Low-Defect Manganese-Based Prussian Blue Cathode Materials with Cubic Structure for Sodium-Ion Batteries via Coprecipitation Method.

Sodium-ion batteries have important application prospects in large-scale energy storage due to their advantages, such as safety, affordability, and abundant resources. Prussian blue analogs (PBAs) have a stable and open framework structure, making them a very promising cathode material. However, high-performance manganese-based Prussian blue cathode materials for sodium-ion batteries still suffer from significant challenges due to several key issues, such as a high number of vacancy defects and a high crystal water content. This article investigates the effects of the Fe-Mn molar ratio, Mn ion concentration, and reaction time on the electrochemical performance of MnHCF during the coprecipitation process. When Fe:Mn = 1:2, c(Mn2+) = 0.02 mol/L, and the reaction time is 12 h, the content of interstitial water molecules in the sample is low, and the Fe(CN)6 defects are few. At 0.1 C, the prepared electrode has a high initial discharge specific capacity (121.9 mAh g-1), and after 100 cycles at 0.2 C, the capacity retention rate is 65% (~76.2 mAh g-1). Meanwhile, the sample electrode exhibits excellent reversibility. The discharge capacity can still be maintained at around 75% when the magnification is restored from 5 C to 0.1 C. The improvement in performance is mainly attributed to two aspects: On the one hand, reducing the Fe(CN)6 defects and crystal water content is conducive to the diffusion and stable structure of N. On the other hand, reducing the reaction rate can significantly delay the crystallization of materials and optimize the nucleation process.

Multifunctional Interlayer Engineering for Silkworm Excrement-Derived Porous Carbon Enabling High-Energy Lithium Sulfur Batteries.

Lithium-sulfur (Li-S) batteries show advantage of high theoretical capacity. However, the shuttle effect of polysulfides and sluggish sulfur redox kinetics seriously reduce their service life. Inspired by the porous structural features of biomass materials, herein, a functional interlayer is fabricated by silkworm excrement-derived three-dimensional porous carbon accommodating nano sized CoS2 particles (SC@CoS2 ). The porous carbon delivers a high specific surface area, which provides adequate adsorption sites, being responsible for suppressing the shuttle effect of polysulfides. Meanwhile, the porous carbon is favorable for hindering the aggregation of CoS2 and maintaining its high activity during extended cycles, which effectively accelerates the polysulfides conversion kinetics. Moreover, the SC@CoS2 functional interlayer effectively limits the formation of Li dendrites and promotes the uniform deposition of Li on the Li electrode surface. As a result, the CMK-3/S cathode achieves a high initial capacity of 1599.1 mAh g-1 at 0.2 C rate assisted by the polypropylene separator coated with the functional interlayer and 1208.3 mAh g-1 is maintained after the long cycling test. This work provides an insight into the designing of long-lasting catalysts for stable functional interlayer, which encourages the application of biomass-derived porous carbon in high-energy Li-S batteries.

Dual-atoms iron sites boost the kinetics of reversible conversion of polysulfide for high-performance lithium-sulfur batteries

Atomically dispersed metal catalysts have offered significant potential for accelerating sluggish kinetics of lithium polysulfides conversion and inhibiting the shuttle effect, so as to achieve the long-life cycle and high-rate performance of lithium sulfur batteries. However, the end-on adsorption structure between single metal site and polysulfide limits the adsorption capacity and catalytic activity of single atom catalysts. Here, we construct dual-atoms iron sites on nitrogen doped graphene to serve as highly efficient catalyst for lithium sulfur batteries. As expected, the dual-atoms sites can firmly bind polysulfides by forming double Fe-S bonds between polysulfides and the two adjacent iron atoms. Such double-bond adsorption structure is also favorable for electron transfer and polysulfides activation, resulting in reducing the energy barrier and accelerating the reaction kinetics. As a result, the as-obtained dual-atoms iron catalyst can effectively alleviate the shuttle effect and improve the utilization of active sulfur, thus the batteries present high initial capacity of 1615 mAh g−1 at 0.05 C and long-cycle life with a decay rate per cycle as low as 0.015% at 2C over 1000 cycles.

Rational design of MoSSe nanosheets on N-doped carbon hollow spheres for accelerating polysulfide redox kinetics of high-performance lithium-sulfur batteries

Lithium-sulfur (Li-S) batteries with high theoretical energy densities offer a promising alternative for next-generation energy storage. However, the poor conductivity, shuttle effect of lithium polysulfides (LiPSs), and large volume expansion upon cycling hinder their application. Hollow nanostructures can play an important role in achieving high sulfur loading, buffering volume expansion, and inhibiting LiPSs shuttling. In this work, MoSSe nanosheets grown on N-doped carbon hollow spheres (MoSSe/NC) are used as both sulfur host and separator to achieve catalytic adsorption and conversion of LiPSs. As a sulfur host, MoSSe/NC can enhance electron/ion transport and alleviate the volume expansion of sulfur during cycling, further accelerating the redox kinetics. The MoSSe/NC-modified separator can also induce interfacial charge modulation and expose more active sites, promoting rapid anchoring and conversion of LiPSs and uniform deposition of Li2S. Theoretical calculations and experiments verify that MoSSe/NC can catalyze the conversion of LiPSs, inhibit the shuttle effect, and effectively improve the electrochemical properties of sulfur. Therefore, the MoSSe/NC based Li-S battery exhibits high initial capacity (1455 mAh g−1), excellent rate performance (891 mAh g−1 at 2 C), and good cycling stability (0.049% capacity decay rate at 800 cycles at 1 C).

An all-biomaterials-based aqueous binder based on adsorption redox-mediated synergism for advanced lithium–sulfur batteries

The complex multistep electrochemical reactions of lithium polysulfides and the solid–liquid–solid phase transformation involved in the S8 to Li2S reactions lead to slow redox kinetics in lithium–sulfur batteries (Li–S batteries). However, some targeted researches have proposed strategies requiring the introduction of significant additional inactive components, which can seriously affect the energy density. Whereas polymer binders, proven to be effective in suppressing shuttle effects and constraining electrode volume expansion, also have promising potential in enhancing Li–S batteries redox kinetics. Herein, a novel aqueous polymer binder is prepared by convenient amidation reaction of fully biomaterials, utilizing its inherent rich amide groups for chemisorption and redox mediating ability of thiol groups to achieve adsorption redox-mediated synergism for efficient conversion of polysulfides. Li–S batteries based on N-Acetyl-L-Cysteine-Chitosan (NACCTS) binder exhibit high initial discharge specific capacity (1260.1 ​mAh ​g−1 at 0.2 ​C) and excellent cycling performance over 400 cycles (capacity decay rate of 0.018% per cycle). In addition, the batteries exhibit great areal capacity and stable capacity retention of 83.6% over 80 cycles even under high sulfur loading of 8.4 ​mg ​cm−2. This work offers a novel perspective on the redox-mediated functional design and provides an environmentally friendly biomaterials-based aqueous binder for practical Li–S battery.

Exploring the effect of lithium halide artificial SEI on the electrochemical performance of lithium metal batteries

The urgent need for high-energy–density rechargeable batteries is driving lithium (Li) metal as a promising anode material. However, the conventional solid electrolyte interface (SEI) on lithium metal suffers from elevated interfacial impedance, poor mechanical properties, and non-uniform Li+ flux. Previously, LiF has been proven to be an effective component of the SEI protecting lithium metal. However, this is a rarely reported application of LiCl and LiBr in SEI. Herein, we design SEI containing lithium halide in different ratios (LiF0.8Cl0.1Br0.1, LiF0.33Cl0.33Br0.33, LiCl, LiBr) to investigate the action laws of lithium halide in SEI. It has been shown that the performance of SEI containing lithium halide against lithium anode increases with the LiF content in the SEI. The higher the proportion of LiF in SEI, the better the cycle life and stability of Li-Li symmetric cells, and the higher the initial capacity and the capacity retention of LFP-Li full cells. The symmetric cell with LiF0.8Cl0.1Br0.1@Li has the smallest average polarization voltage (about ± 30 mV) and long cycle life of up to 1000 h. LiFePO4||LiF0.8Cl0.1Br0.1@Li cells have the highest initial capacity (127.4 mAh/g), and still had 83.6 % capacity retention after 1000 cycles at 2C.

Cathode Interface Construction by Rapid Sintering in Solid-State Batteries.

Solid-state batteries (SSBs) are poised to replace traditional organic liquid-electrolyte lithium-ion batteries due to their higher safety and energy density. Oxide-based solid electrolytes (SEs) are particularly attractive for their stability in air and inability to ignite during thermal runaway. However, achieving high-performance in oxide-based SSBs requires the development of an intimate and robust SE-cathode interface to overcome typically large interfacial resistances. The transition interphase should be both physically and chemically active. This study presents a thin, conductive interphase constructed between lithium aluminum titanium phosphate and lithium cobalt oxide using a rapid sintering method that modifies the interphase within 10s. The rapid heating and cooling rates restrict side reactions and interdiffusion on the interface. SSBs with thick composite cathodes demonstrate a high initial capacity of ≈120mAhg-1 over 200 cycles at room temperature. Furthermore, the rapid sintering method can be extended to other cathode systems under similar conditions. These findings highlight the importance of constructing an appropriate SE-cathode interface and provide insight into designing practical SSBs.
