A proof‐of‐principle study is presented on the rechargeable anion storage capability of ferrocyanide immobilized in a polysilsesquioxane (PSQ)‐modified flexible/rigid film for aqueous battery applications. This electrode material delivers high power density up to 140 μWh cm⁻² and energy density of 9.4 μWh cm⁻² with a long cycle life of more than 200 cycles in chloride ion medium. The proposed energy storage mechanism of this system is based on insertion and extraction of the anion into the [Fe(CN)₆]⁴⁻−PSQ film during charging and discharging processes, respectively. Moreover, a hybrid battery–capacitor device comprising a graphite rod (capacitor) and the ferrocyanide‐immobilized PSQ film as a faradaic electrode shows enhanced electrochemical performance.

柔性阴离子微电池：朝着混合电池－电容器设备的方向发展

原理研究针对固定在聚倍半硅氧烷（PSQ）改性的柔性/刚性膜中的亚铁氰化物的可充电阴离子存储能力进行了研究，适用于水性电池应用。此电极材料提供高功率密度高达140μWh厘米^-2 9.4μWh厘米的和能量密度^-2与氯离子介质超过200个循环的循环寿命长。该系统提出的能量存储机制是基于阴离子向[Fe（CN）₆ ] ^4-的插入和提取。-PSQ膜分别在充电和放电过程中。此外，包含石墨棒（电容器）和固定有亚铁氰化物的PSQ薄膜作为法拉第电极的混合电池电容器装置显示出增强的电化学性能。
