Advanced Materials, Journal Year: 2024, Volume and Issue: 36(47)

Published: Oct. 10, 2024

Abstract Interest in all‐solid‐state batteries (ASSBs), particularly the anode‐less type, has grown alongside expansion of electric vehicle (EV) market, because they offer advantages terms their energy density and manufacturing cost. However, most ASSBs, anode is covered by a protective layer to ensure stable lithium (Li) deposition, thus requiring high temperatures adequate Li ion diffusion kinetics through layer. This study proposes dual‐seed consisting silver (Ag) zinc oxide (ZnO) nanoparticles for sulfide‐based ASSBs. dual‐seed‐based not only facilitates via multiple lithiation pathways over wide range potentials, but also enhances mechanical stability interface situ formation Ag–Zn alloy with ductility. The capacity retention during full‐cell evaluation 80.8% 100 cycles when cycled at 1 mA cm −2 3 mAh room temperature. approach provides useful insights into design multi‐seed concepts which, from mechanochemical perspective, various lithiophilic materials synergistically impact upon interface.

Published: Feb. 11, 2025

Solid electrolytes, as the core of all-solid-state batteries (ASSBs), play a crucial role in determining kinetics ion transport and interface compatibility with cathodes anodes, which can be subdivided into catholytes, bulk anolytes based on their functional characteristics. Among various inorganic solid ductile distinguished from rigid oxide exhibit excellent properties even under cold pressing, thus holding greater promise for industrialization. However, challenge lies finding electrolyte that simultaneously serve catholyte, electrolyte, anolyte. Fortunately, due to immobility combining multiple types electrolytes allows leveraging respective advantages. In this review, we discuss five sulfides, halides, nitrides, antiperovskite-type, complex hydrides, challenges superiorities these are also addressed. The impact pressure ASSBs has been systematically discussed. Furthermore, suitability anolyte is discussed characteristics physicochemical properties. This discussion aims deepen our understanding enabling us harness advantages develop practical, high-performance ASSBs.

Sulfide-Based Anode-Free Solid-State Batteries: Key Challenges and Emerging Solutions

ACS Energy Letters, Journal Year: 2025, Volume and Issue: 10(5), P. 2377 - 2391

Published: April 17, 2025

Sulfide-based anode-free solid-state batteries (AFSSBs) have emerged as a transformative technology for next-generation energy storage, offering compelling advantages in density, safety, and manufacturing scalability. However, these face significant challenges, particularly rapid capacity degradation that currently limits their practical implementation. This comprehensive review critically examines three fundamental issues affecting AFSSBs: nonuniform lithium nucleation on bare current collectors, unstable interfaces between plated sulfide electrolytes, formation of interfacial voids during cycling. We systematically evaluate recent strategic advances addressing including metal seed coatings, conversion reaction-based compounds, carbon-based interlayers. The also analyzes the crucial role advanced characterization techniques, from cryo-FIB-SEM to operando methods, understanding failure mechanisms validating improvement strategies. Finally, we present forward-looking perspective research directions necessary commercialization. work provides thorough framework advancing sulfide-based AFSSBs toward applications storage systems.

All‐Solid‐State Batteries with Extremely Low N/P Ratio Operating at Low Stack Pressure

Advanced Energy Materials, Journal Year: 2024, Volume and Issue: unknown

Published: Dec. 15, 2024

Abstract All‐solid‐state batteries (ASSBs) are emerging as promising candidates for next‐generation energy storage systems. However, their practical implementation faces significant challenges, particularly requirement an impractically high stack pressure. This issue is especially critical in high‐energy density systems with limited negative‐to‐positive electrode capacity ratios (N/P ratios), where uneven lithium (Li) stripping induces the formation of interfacial voids. study addresses these challenges by introducing anode a novel structural design that operates effectively under practically viable conditions while significantly reducing N/P ratio to less than one. The approach entails integration lithiophilic magnesium (Mg) film beneath thin layer silicon‐graphite (SiGr) active materials. structure facilitates deposition excess Li SiGr during overcharging, which enables stable cycling even at room temperature and low pressure 3 MPa. By mitigating poor contact characteristic ASSBs pressure, simultaneously increasing lowering ratio, advances key electrochemical properties ASSBs.
