Abstract

This chapter highlights the development of manganese oxide (MnO2) as cathode material in rechargeable zinc ion batteries (ZIBs). Recently, renewed interest in ZIBs has been witnessed due to the demand for economical, safe, and high performance rechargeable batteries which is the current limitation of the widely used rechargeable lithium ion batteries (LIBs). ZIBs in comparison with LIBs have a high volumetric capacity and an abundance of raw material. ZIBs are also non-toxic and safe. Besides, production of ZIBs does not require sophisticated equipment such as vacuum technology. In fact, ZIBs can be manufactured even under ambient atmosphere. Of the interesting cathode materials for ZIBs such as V2O5 and Prussian Blue analogs, MnO2 attracts much research attention due to its rich electrochemistry, size, morphology, phase, and structure. Similar to Zn, MnO2 is plentiful and safe. It is evident that when paired up with zinc, MnO2 can deliver a high theoretical capacity of 308 mAh g 1. However, the inherent poor conductivity and poor cyclability of this material are common drawbacks for its potential usage.
