通过近表面氟调控重构残余岩盐相，实现再生 NCM622 正极 4.6 V 稳定循环
Engineering Residual Rock‐Salt Reconstruction through Near‐Surface Fluorine Regulation for Stable 4.6 V Cycling of Regenerated Spent Layered Oxide Cathodes
模型导读
研究者采用近表面氟调控策略，将废 LiNi0.6Co0.2Mn0.2O2（NCM622）正极表面残余岩盐相重构为富氟岩盐界面层，所得 RFNCM 正极在 3.0-4.6 V、0.1 C 下放电比容量达 208.7 mAh g−1，1 C、25°C 循环 400 次容量保持 80.28%，50°C 循环 200 次保持 80.93%。
