This research aims to improve the electrochemical performance of manganese-based oxide cathodes in aqueous zinc-ion batteries through doping.
Synthesize pristine and doped Mn2O3 materials using a Mn-organic framework template method.
Investigate the structural, morphological, and electrochemical effects of different doping elements at varying concentrations.
Analyze the performance of different doped materials under controlled cycling conditions.
Nickel (Ni) doping at a 5% level yields a discharge specific capacity of 201.7 mA h g–1 at 0.1 A g–1 after 100 cycles.
The material retains a reversible capacity of 61.3 mA h g–1 after 500 cycles at 0.5 A g–1, demonstrating superior cycling stability.
Ni2+ doping enhances oxidation of Mn3+ to Mn4+, reduces charge transfer resistance, and improves bulk diffusion coefficient of Zn2+.
