Research Progress of Zinc Anode Materials for Aqueous Zinc Ion Recharge Battery

Zinc ion recharge battery is a promising energy storage device with excellent charge-discharge performance, high power density and energy density, low cost, high safety and environment friendly. Metal zinc has been regarded as an ideal anode material for aqueous recharge batteries due to its excellent conductivity, relatively low redox potential, high theoretic capacity and low cost. As the negative electrode material of zinc ion recharge battery, metal zinc has some problems such as dendrite growth, corrosion and passivation, which result in the limit of the reversible capacity and cycle life of zinc ion recharge battery. However, the performance of zinc anode can be improved by controlling its morphology and surface modification. Herein, we review the development of anode materials for zinc ion batteries, including metal zinc anode, composite zinc anode and zinc alloy, and the prospects for zinc anode.
