NH 4+-mediated interfacial chemistry for collaborative dual-pathway high-mass-loading energy storage
NH 4+-mediated interfacial chemistry for collaborative dual-pathway high-mass-loading energy storage
研究概述
调控NH4+介导的MnO2界面化学及部分羟基化程度，协同实现MnO2/Mn2+可逆转化和NH4+储存。在27.1 mg/cm²高负载下获得13.8 F/cm²面电容，并稳定循环6000次；计算表明界面电荷重分布降低转化限速步骤的能垒。
