A Physical Mechanism for Suppression of Zinc Dendrites Caused by High Efficiency of the Electrodeposition within Confined Nanopores

A strategy for the suppression of zinc dendrites in electrodeposition controlled by a physical factor has been proposed and demonstrated. Zinc electrodeposition within confined nanopores shows a high current efficiency even at a current density higher than the diffusion-limited current measured on a planar substrate. Our results suggest that the electrodeposition is free from the diffusion-limitation problem only when the electrodeposition occurs within the confined nanopores.
