The advantages of manganese, such as its abundance in the Earth's crust, high redox potentials, low cost, and environmental friendliness, have facilitated extensive research on using manganese oxides as potential cathode materials for Zn batteries. Another factor that attracts the usage of manganese oxides is the. Vanadium oxides are being studied as a potential cathode material for Zn batteries because of its multivalence nature, availability, and high capacity (up to 400 mA h g−1) but have a low. PBAs are characterized by large 3D open-framework features, ample redox-active sites, and strong structural stabilities. They have a general formula of AxM[M' (CN)6]y.nH2O, where A.
