Li2FeS2 表面结合界面实现全固态 Li–S 电池 97.8% 硫利用率
Ion‐Electron Convergent Interphases Enable Ultrahigh Sulfur Utilization for All‐Solid‐State Li–S Batteries
AI 导读
研究提出在 Li2S 表面构建表面结合的离子-电子汇聚界面，将原本局域的三相接触重构为一体化活性表面，并以源自自旋不对称的有效磁矩作为界面亲和性的筛选判据，据此识别出 Li2FeS2 能与 Li2S 形成稳固的表面结合界面。
推荐理由
作者以有效磁矩筛选界面亲和性，在 Li2S 表面构建离子-电子汇聚界面，读者可看到硫利用率与面容量同时提升的设计思路。
创新点
用有效磁矩作为界面亲和性筛选判据，找到与 Li2S 形成表面结合界面的 Li2FeS2，把分离的离子与电子通路在反应区合并为一体化活性表面，从而缓解绝缘硫/Li2S 的传输瓶颈。
