The increasing demand for safe lithium-ion batteries with high energy density has pushed the development of all-solid-state batteries (ASSBs). With the development of promising solid electrolytes (SEs) such as Li₁₀GeP₂S₁₂ and Li₆PS₅Cl with high ionic conductivity in recent years, the bottleneck for high-performance ASSBs is no longer sluggish Li⁺ diffusion caused by SEs. Furthermore, significant improvement in the cycle performance has been achieved by understanding electrochemomechanical properties, preventing undesirable side reactions between SEs and active materials, and employing advanced packaging technology. However, poor rate capability caused by several factors, including sluggish Li⁺ kinetics at the interface between active materials and SEs, poor interfacial contact between particles, thick SE layers, and Li dendrite growth, limits the practical applications, especially in electric vehicles. The high-rate performance is of paramount importance in the current development of battery technology. In this review, the fundamental understanding of the parameters governing the rate capability in ASSBs is discussed and the distinctive features and research strategies toward high-rate performance are highlighted. The discussion and perspectives about kinetic rate limitations and research strategies are expected to stimulate further progress in fast charging ASSBs.

迈向高倍率性能固态电池

对具有高能量密度的安全锂离子电池的需求不断增长，推动了全固态电池（ASSB）的发展。随着近年来具有高离子电导率的Li ₁₀ GeP ₂ S ₁₂和Li ₆ PS ₅ Cl 等有前景的固体电解质（SEs）的发展，高性能ASSBs的瓶颈不再是Li ⁺由 SE 引起的扩散。此外，通过了解电化学机械特性、防止 SE 和活性材料之间的不良副反应以及采用先进的封装技术，循环性能得到了显着改善。然而，由于 Li ^{+低迷等多种因素导致倍率能力差}活性材料和 SE 之间的界面动力学、颗粒之间的界面接触差、SE 层厚和锂枝晶生长限制了实际应用，尤其是在电动汽车中。高倍率性能在当前电池技术的发展中至关重要。在这篇综述中，讨论了对 ASSB 中速率能力参数的基本理解，并强调了高速性能的独特特征和研究策略。关于动力学速率限制和研究策略的讨论和观点有望刺激快速充电 ASSB 的进一步进展。
