硅基负极多场耦合失效机制与解耦策略研究进展
Research progress on multi-field coupled failure mechanisms and decoupling strategies for silicon-based anodes
摘要
Abstract
Silicon-based anodes are regarded as key materials for next-generation lithium-ion batter-ies due to their high theoretical specific capacity.However,their significant volume changes during lithiation/delithiation lead to multi-field coupled failure,severely hindering their practical engineer-ing application.This review analyzed the stress accumulation,crack propagation behavior,and their complex interactions with electrochemical and thermal effects in silicon anodes during cycling.From a practical application perspective,multiple engineering-feasible decoupling strategies were dis-cussed,including the design of high-performance binders,gradient interface modulation,porous buf-fer structures,electrode curvature optimization,and system-level thermal-pressure management.The technical pathways for enhancing the cycling stability and safety of silicon-based anodes through multi-scale regulation were summarized,and future key challenges in mechanistic research and model development were outlined.关键词
