摘要

封面特征展示了一种全固态锂金属电池，其聚合物电解质（spe）基于带有螺缩醛环的聚碳酸酯共聚物。聚碳酸酯共聚物的粘弹性特性使其与锂阳极和LFP阴极都具有良好的粘附性，从而实现稳定的充放电循环。x射线光发射光谱分析表明，中等厚度和富锂的阴极电解质界面（CEI）可以提高电池的稳定性能。这项研究发表在富永及其同事的研究文章中（DOI: 10.1002/batt）。202500237)提供了针对未来应用（如柔性设备）的新型spe的设计指南。

Cover Feature: Development of All-Solid-State Lithium Metal Batteries Using Polymer Electrolytes Based on Polycarbonate Copolymer with Spiroacetal Rings (Batteries & Supercaps 10/2025)

The Cover Feature illustrates an all-solid-state lithium metal battery with polymer electrolytes (SPEs) based on polycarbonate copolymer with spiroacetal rings. The viscoelastic properties of the polycarbonate copolymer enable excellent adhesion to both the lithium anode and the LFP cathode, resulting in stable charge–discharge cycling. X-ray photoemission spectroscopy analysis shows that a moderately thick and LiF-rich cathode electrolyte interphase (CEI) gives rise to stable battery performance. The study reported in the Research Article by Y. Tominaga and co-workers (DOI: 10.1002/batt.202500237) provides design guidelines for novel SPEs aimed at future applications such as flexible devices.
