Core-shell structured Mn2O3@ZnMn2O4/C hollow microspheres are reported as an ideal cathode material for AZIBs, addressing the problems of capacity decline and low-rate performance. Its application in AZIBs demonstrates satisfactory rate performance, high cycle stability, and excellent reversibility. With a high reversible capacity reaching 289.9 mA h g(-1) and maintaining 203.5 mA h g(-1) after cycling 700 times at 1000 mA g(-1), this material shows great potential for AZIBs.
Manganese-based oxides are common cathode materials for aqueous zinc ion batteries (AZIBs) because of their great capacity and high working voltage. However, the sharp decline of capacity caused by the dissolution of manganese-based cathode materials and the low-rate performance restrict their development. To address these problems, unique core-shell structured Mn2O3@ZnMn2O4/C hollow microspheres are reported as an ideal cathode material for AZIBs. Benefiting from the hollow structure, the zeolitic imidazolate framework (ZIF)-derived carbon and ZnMn2O4. Its application in AZIBs as the cathode demonstrates its satisfactory rate performance, high cycle stability, and excellent reversibility. Its high reversible capacity is remarkable, which reaches its maximum of 289.9 mA h g(-1) at 200 mA g(-1) and maintains a capacity of 203.5 mA h g(-1) after cycling for 700 times at 1000 mA g(-1). These excellent performances indicate that this material is a potential cathode material of AZIBs.
