4d orbital ruthenium doping enables high-capacity and stable α-MnO2 cathodes for aqueous zinc-ion batteries
{{output}}
The electrochemical performance of α-MnO2 cathodes in aqueous zinc-ion batteries is limited by their low electronic conductivity, structural instability due to Jahn-Teller distortion, and slow Zn2+ diffusion kinetics. Although ion doping can alleviate these i... ...
