“…[5][6][7] Among them, the rechargeable zinc ion battery has aroused considerable attention due to its admirable safety, cost-effectiveness, moderate redox potential (−0.76 V vs. SHE), and decent theoretical capacity (∼820 mA h g −1 ) of the Zn anode. 6,8,9 However, the zinc ion battery is still in its infancy, and one of the core tasks aim to prompt the development of the zinc ion battery is to screen out competent cathode materials that can sustainably serve for repeated Zn 2+ intercalation/deintercalation. 5,6 The past several years have witnessed a considerable increase in the research efforts for cathode materials' screening and great progresses have been achieved.…”
