A Solid Solution Alloy Current Collector to Stabilize Zinc Metal Anode

Abstract

Dendrite growth limits the performance of aqueous zinc-metal batteries. Here, we present a Cu–In solid solution alloy current collector, where indium enhances zinc affinity and lowers nucleation overpotential, enabling dendrite-free zinc deposition. The Zn@Cu–In anode demonstrates stable cycling at high current densities.
