Solid‐state lithium metal batteries (SSLMBs) are believed to be important pathway to overcome the limitations that state‐of‐the‐art lithium‐ion batteries face in terms of safety and energy density. In addition to transporting ionic species in solid‐state configuration, solid polymer electrolytes (SPEs) are structurally designable and processable, and have been deemed as an auspicious kind of solid electrolyte to access highly‐performant SSLMBs. In this essay, we provide a historical overview on the development of SPE‐based SSLMBs, aiming to highlight the main achievements being made at both material and cell levels. It is hoped that the personal reflection and retrospect presented in this essay give an impetus to inspire the discovery of tantalizing battery materials and improve the overall performance of SPE‐based SSLMBs and other emerging battery technologies.

基于固态聚合物电解质的固态锂金属电池的历史：个人经历

固态锂金属电池（SSLMB）被认为是克服现有锂离子电池在安全性和能量密度方面面临的局限性的重要途径。除了以固态配置运输离子物质外，固体聚合物电解质（SPE）在结构上也是可设计和加工的，并且被视为一种可访问高性能SSLMB的吉祥固体电解质。在本文中，我们对基于SPE的SSLMB的发展进行了历史回顾，旨在强调在材料和细胞水平上所取得的主要成就。
