CMC/PAA双聚合物界面层稳定锌粉负极，软包电池1000次循环保持89.2%容量
A Particle‐Level Dual‐Polymer Interphase for Coupled Interfacial and Contact Stabilization of Zinc Metal Powder Anodes in Aqueous Zinc‐Ion Batteries
AI 导读
研究在锌金属粉末（ZnMP）负极上构建由羧甲基纤维素（CMC）和聚丙烯酸（PAA）组成的双聚合物界面层（C/P@ZnMP），CMC基体调控局部水环境、抑制水相关界面降解，PAA提供羧基/羧酸根位点以提高Zn²⁺亲和力，两者协同限制副产物累积并改善电解液对粉末电极的浸润。
推荐理由
针对锌粉负极曲表面与点接触问题，用CMC/PAA双聚合物界面层同时调控界面副反应与电子接触，并给出软包电池循环数据。
创新点
将CMC的界面水环境调控与PAA的Zn²⁺亲和位点整合为颗粒级双聚合物界面层，同时应对锌粉的界面副反应与粉末骨架内的接触损失。
