氟化聚离子液体电解质借离子配体辅助传输实现 515 Wh kg⁻¹ 固态锂金属电池
Ionic‐Ligand‐Assisted Transport in Fluorinated Poly(ionic liquid) Electrolytes Enables 515 Wh Kg −1 Solid‐State Lithium Metal Batteries
AI 导读
研究将氟化丙烯酸酯聚合物与聚离子液体（PIL）共聚并优化 LiFSI 浓度，构建离子配体辅助传输框架，DFT 与分子动力学模拟显示阳离子 PIL 锚定 FSI⁻ 阴离子形成富阴离子的空间关联配位通道，促进 Li+ 跳跃传输。
推荐理由
通过氟化丙烯酸酯与聚离子液体共聚并调控 LiFSI 浓度，把离子电导与链段松弛解耦，给出 30°C 下 0.77 的 Li+ 迁移数。
创新点
用阳离子 PIL 锚定 FSI⁻ 构建富阴离子配位通道，使离子传导不再依赖聚合物链段松弛，从而同时获得高离子电导与高 Li+ 迁移数。
