Three-dimensional (3D) Zn powders are usually used as anode materials for aqueous zinc-ion batteries, but the problems of dendrites, structural instability, hydrogen generation, and side reactions caused by their large activity and special spherical structure greatly limit the stability of the anode. The idea of dimensionality reduction for the Zn powders by using mechanical ball milling to design a stable two-dimensional (2D) Zn powder anode is proposed in this work. The special planar structure of the 2D-Zn powder displays significant advantages in buffering the formation of dendrites, side ...
