用组分分辨框架定量钠离子电池SEI有机与无机组分的溶解
Quantifying the Dissolution of Organic and Inorganic Components in Solid Electrolyte Interphase for Sodium‐Ion Batteries
AI 导读
研究团队建立了一个组分分辨的定量框架，结合离子色谱、质谱、电化学石英晶体微天平和XPS，分别量化钠离子电池SEI中有机与无机组分的溶解与保留，给出绝对保留量而非总体界面损失。
推荐理由
作者用离子色谱、质谱、电化学石英晶体微天平和XPS组合，把SEI有机与无机组分的溶解与保留分开定量，读者可据此比较不同电解液下的界面稳定性。
创新点
把SEI溶解从总体界面损失拆成有机与无机组分的绝对保留量，并据此把醚链长与Na+溶剂化结构、SEI组成和软包电池循环稳定性连成一条可量化的因果链。
