MnO₂ Nanosheet‐Assembled Hollow Polyhedron Grown on Carbon Cloth for Flexible Aqueous Zinc‐Ion Batteries

Aqueous zinc‐ion batteries (ZIBs) have been considered as prospective alternatives for lithium‐ion batteries, which are able to serve as power sources for next‐generation wearable and flexible devices, owing to the merits of abundant zinc resources and high safety of aqueous electrolyte. However, the lack of suitable cathode materials with flexibility for ZIBs hinders their further application. Herein, a novel cathode material [i.e., MnO 2...
