The mechanical integrity and electrochemical cyclability of a Sn anode for next‐generation lithium‐ion batteries are significantly improved by a surface Cu–Sn intermetallic coating layer (ICL) through a structural reconstruction mechanism, which is presented by Yang Yang and co‐workers in article number 2003684. The Cu–Sn ICL provides a regulatable and appropriate distribution of Cu to buffer the volume change of the Sn anode, mitigating the internal stress and suppressing mechanical degradation.

阳极材料：通过结构重构Cu-Sn金属间镀层来稳定Sn阳极（Adv。Mater。42/2020）

新一代锂离子电池的锡阳极的机械完整性和电化学循环性通过结构重构机制通过表面铜-锡金属间涂层（ICL）得到了显着改善，该结构重构机制由杨扬及其同事在物品编号为2003684。Cu-Sn ICL提供可调节且适当的Cu分布，以缓冲Sn阳极的体积变化，从而减轻内部应力并抑制机械降解。
