亚分子硒正极使全固态Li–Se电池在低堆叠压力下可循环且可回收
Submolecular Selenium Enables Low‐Pressure and Recyclable All‐Solid‐State Li–Se Batteries
AI 导读
研究将晶态cyclo-Se8转化为锚定在石墨烯上的非晶单原子与短链Se（Sex，x<4），使电子电导率从6.3×10⁻⁵提升至13 S cm⁻¹，Li⁺扩散系数从1.7×10⁻¹⁴提升至2.0×10⁻¹¹ cm² s⁻¹。
推荐理由
亚分子Se物种把电子电导率提升约五个数量级，并给出8 MPa与2.5 MPa下的循环数据，可供判断低堆叠压力固态电池的界面设计空间。
创新点
把晶态cyclo-Se8拆成锚定在石墨烯上的非晶单原子与短链Sex物种，同时用Li2O纳米壳修饰硫化物电解质稳定两侧界面，使低堆叠压力下的全固态Li–Se电池兼具高电导与可回收性。
