Finding a suitable cathode material for Zn-ion batteries with adequate structural stability and high capacity is an uphill task for researchers. This review presents the recent developments of various cathode materials in zinc ion batteries and their effectiveness towards the advancement of Zn-ion batteries.
Therefore, the use of zinc as a battery material can meet the requirements of environmental protection and low cost. The volume energy density of zinc can reach 5855 Wh·L −1. And the reoxidation potential of zinc is −0.76 V, which is lower than the standard hydrogen potential 1.23 V.
However, as for the Li-ion battery, the Zn-ion battery also has its own inadequacies in terms of cathodes. Finding a suitable cathode material for Zn-ion batteries with adequate structural stability and high capacity is an uphill task for researchers.
These battery systems generally consist of zinc–air batteries (Zn/air), zinc–manganese batteries (Zn/MnO 2), zinc–nickel batteries (Zn/NiOOH), and zinc–silver batteries (Zn/AgO). Zinc-based manufacturing industries should adopt sustainable environmental policies if a massive number of primary batteries can be transformed into secondary batteries.
Researchers have not only studied the reaction mechanism of manganese oxides, but have also considered other cathode materials with zinc storage mechanisms, e.g., the vanadium-based compounds , , organic compounds , and PBAs that are discussed in the following sections.
Rechargeable zinc-ion batteries (RZIBs) are one of the most promising candidates to replace lithium-ion batteries and fulfill future electrical energy storage demands due to the characters of high environmental abundance, low cost and high capacities (820 mAh g −1 /5855 mAh cm −3).
