Abstrakt: This article discusses the development of a cathode material for zinc ion batteries (ZIBs) that has a long lifespan and high areal capacity. The researchers propose a strategy of doping Fe heteroatoms and coating with reduced graphene oxide (rGO) to improve the performance of the cathode material. The Fe-doped a-MnO2/rGO cathode material exhibits high specific and rate capacities, as well as impressive areal capacity. The researchers used calculations and electrochemical measurements to evaluate the performance of Fe-doped a-MnO2 as a cathode material in zinc-ion batteries. The results showed that Fe doping improved the electronic conductivity of a-MnO2 and enhanced its electrochemical performance. The material shows promise for practical applications in ZIBs.
