Abstract: Aqueous zinc ion batteries have high application value and development prospects in large-scale
energy storage and other fields. At present, research on cathode materials for aqueous zinc ion batteries
mainly focuses on manganese-based compounds (such as manganese dioxide, manganese trioxide,
trimanganese trioxide), vanadium-based oxides, and Prussian blue analogs. Among them, manganese
dioxide has become the most concerned type of cathode material and has been rapidly developed in recent
years due to their excellent electrochemical performance, abundant reserves, low price, safety and
environmental protection. However, during the charging and discharging process, the crystal form of
manganese dioxide is changeable and accompanied by other surface reactions, and its reaction mechanism
is complicated and there are certain disputes. In the past two years, with the continuous deepening of
research, its electrochemical reaction mechanism has gradually become clear. The crystal structure
characteristics of manganese dioxide and the performance as a positive electrode for aqueous zinc ion
batteries are reviewed. The energy storage mechanism of different crystal manganese dioxide is discussed.
A prospect for its future development is made.
