Flexible electrode materials are of critical importance for advancing the development of flexible Zn-MnO2 rechargeable batteries. However, the slow electron-transfer kinetics and poor structural stability of MnO2 dramatically impede their real-world practices. In this work, we showcase an in situ interfacial fabrication of a highly flexible MnO2@polyaniline (MnO2@PANI) core-shell nanowire film for high-rate and durable zinc energy storage. The conducting polyaniline nanoshell is of grand benefit for expediting the reaction kinetics and stabilizing the electrode. The MnO2@PANI hybrid cathode affords an impressive reversible capacity of 342 mA h g-1 at 0.2 A g-1, and more notably, warrants substantially improved rate and cycling performance. The excellent zinc energy storage is further demonstrated in a flexible device. This encouraging achievement will pave a fresh design roadway for expediting the Zn-MnO2 technology toward smart and flexible electronics.

高度灵活的 MnO2@polyaniline 核壳纳米线薄膜可显着加速锌储能

柔性电极材料对于推进柔性 Zn-MnO 2可充电电池的发展至关重要。然而,MnO 2缓慢的电子转移动力学和较差的结构稳定性极大地阻碍了它们的实际应用。在这项工作中,我们展示了高柔性 MnO 2 @polyaniline (MnO 2 @PANI) 核壳纳米线薄膜的原位界面制造,用于高速和耐用的锌储能。导电的聚苯胺纳米壳对于加速反应动力学和稳定电极有很大的好处。MnO 2 @PANI 混合阴极具有令人印象深刻的 342 mA hg -1可逆容量在 0.2 A g -1下,更值得注意的是,保证了显着提高的速率和循环性能。优异的锌储能在柔性器件中得到进一步证明。这一令人鼓舞的成就将为加快 Zn-MnO 2技术向智能和柔性电子产品的发展铺平新的设计道路。
