The Influence of Nickel and Alkali Metal Additives on Manganese Dioxide Structure and Performance for Rechargeable Zinc-Ion Batteries

Aqueous rechargeable zinc-ion batteries (ZIBs) are a promising addition to the energy storage landscape, particularly supporting the decarbonization of the power sector (i.e., deployment of wind and solar) as a low-cost, high-safety alternative to lithium-ion batteries. Unfortunately, wide-scale ZIB utilization is hindered in part by limited energy storage capacity and operational durability of state-of-the-art Mn oxide cathode materials. As …
