原位凝胶聚合物电解质SiNCO-GPE实现30 mA cm⁻²锂沉积/剥离
Time‐Domain Regulation of Electrolyte Microenvironments Enables 30 mA cm − 2 Stable Lithium Plating/Stripping for High‐Voltage Lithium Metal Batteries
AI 导读
研究提出一种时域响应型原位凝胶聚合物电解质SiNCO-GPE，用(三甲基硅基)异氰酸酯（SiNCO）作为“清除笼”去除痕量水和HF，其反应产物随后参与界面演化。
推荐理由
原文给出SiNCO-GPE在30 mA cm⁻²下70 h、1 mA cm⁻²下超4000 h的锂沉积/剥离数据，可据此判断凝胶聚合物电解质在高电压锂金属电池中的电流承受边界。
创新点
把“时域失配”作为设计出发点，用可清除水与HF的SiNCO原位凝胶电解质让清除产物在循环中动态并入界面层，兼顾初期快速成膜与长期应力缓冲。
