With the increasing demand for high-performance power batteries in electric vehicles, low-altitude economy, military applications, and other fields, existing liquid electrolyte-based battery technologies are gradually becoming incapable of meeting the energy density and safety requirements. New battery systems based on solid electrolytes are the main candidate materials for future power batteries owing to their high safety and energy density. Thus far, researchers have conducted extensive studies on the ionic/electronic transfer mechanisms of solid electrolytes and electrode materials, as well as the cooperative effects and interface issues between them. Although much progress has been made, the practical application of solid-state batteries is still severely limited by the high interface impedance between the solid electrolyte and the anode. This impedance stems from incompatible physical and chemical properties and dynamic interface evolution. This paper focuses on the latest progress in the interface engineering strategies of solid electrolytes and anodes and systematically analyzes the cooperative coupling effect between charge transfer dynamics and mechanical stability at the interface. This review provides insights into the future research in this field, aiming to offer a new perspective to enhance our understanding of solid-state lithium batteries, thereby facilitating their more optimal design and promoting their practical applications.
随着电动汽车、低空经济、军事应用等领域对高性能动力电池的需求不断增加，现有的基于液体电解质的电池技术逐渐无法满足能量密度和安全要求。基于固体电解质的新型电池系统因其高安全性和能量密度，成为未来动力电池的主要候选材料。到目前为止，研究人员对固体电解质和电极材料的离子/电子转移机制，以及它们之间的协同效应和界面问题进行了广泛研究。尽管已经取得了很大进展，但固态电池的实际应用仍然受到固体电解质与负极之间高界面阻抗的严重限制。这种阻抗源于不相容的物理和化学性质以及动态界面演变。本文重点介绍了固体电解质与负极界面工程策略的最新进展，并系统分析了界面电荷转移动力学与机械稳定性之间的协同耦合效应。本综述为该领域的未来研究提供了见解，旨在提供一个新的视角，以加深我们对固态锂电池的理解，从而促进其更优化的设计并推动其实际应用。
