Hollow Mn–Co–O@C Yolk–Shell Microspheres with Carbon Shells as Cathodes Derived from a Double-Metal MOF for Aqueous Zinc-Ion Batteries

ACS Sustainable Chemistry & Engineering, Journal Year: 2023, Volume and Issue: 11(33), P. 12397 - 12405

Published: Aug. 9, 2023

Manganese-based cathodes are promising candidates for aqueous zinc-ion batteries (AZIBs) due to their high-voltage platform, low-price, environmental friendliness, high theoretical capacity, and non-toxicity. Unfortunately, application is restricted issues such as manganese dissolution, poor electrical conductivity, volume expansion, which lead unsatisfactory rate performance fast capacity decay. Hollow Mn–Co–O@C yolk–shell microspheres with carbon shells were fabricated from self-assembled Mn–Co-metal–organic frameworks via combining facile normal temperature annealing methods. achieved an excellent specific of 401 mA h g–1 a retention 94.7% at 2 A after 2000 cycles. Its remarkable properties attributed the hollow structure surface areas mesoporous effectively buffering large change provide additional storage sites rapid electron/ion transfer. Cobalt doping decelerates dissolution Mn2+, so maintain good structural stability improve multielectron redox reaction cobalt, well coating conductivity thermal can further inhibit manganese. The results indicate that hybrid be potential cathode AZIBs.
