Abstract

Manganese dioxide (MnO₂) represents an ideal cathode material for rechargeable aqueous Zn batteries due to its high theoretical capacity (308 mAh g⁻¹), suitable potential (1.4 V vs. Zn²⁺/Zn), natural abundance, and negligible toxicity. However, the capacity and rate capability of MnO₂ deteriorate significantly in thick electrodes owing to its low electrical and ionic conductivities. Herein, we report the design of high mass loading potassium ion stabilized α-MnO₂ (K_0.133MnO₂) nanowire forests on carbon cloth through a seed-assisted hydrothermal method for Zn batteries. The vertically aligned K_0.133MnO₂ nanowire forests with uninterrupted charge transport afford a high area capacity of 3.54 mAh cm⁻² and a capacity retention of 79.2 % over 1000 cycles in aqueous electrolyte. Moreover, the high area capacity and cyclability can be readily transferred to quasi-solid-state devices.
