摘要
Aqueous zinc metal batteries (ZMBs) are considered as the most promising candidate for large-scale energy storage system due to their abundant reserves and high safety. To achieve highly stable zinc metal batteries, it is imperative to inhibit the unavoidable dendrite growth, which leads to the non-uniform zinc deposition and even makes the battery short circuit. Herein, Sn coating is loaded on copper foil (SCF) by a simple electrodeposition to guide the uniform zinc deposition, which not only lowers the zinc nucleation overpotential but also promotes the uniform zinc deposition/dissolution. As a result, the Zn plated SCF ([email protected]) anode presents a low voltage hysteresis of ∼40 mV and a superior stability over 270 h in symmetric cells at a current density of 1 mA cm−2. Furthermore, the [email protected] anode can realize the improved performance for full cells paired with α-MnO2 cathode. This work provides a simple and effective approach to modify the Zn anode for improved electrochemical performance of ZMBs.
