Role of Mo and N doping ratios in regulating the zinc storage performance of δ-MnO 2 : a systematic study from single to co-doping

Key Points

• To investigate how different ratios of Mo and N doping affect the zinc storage performance of δ-MnO2.
• Systematic study of Mo and N doping ratios in δ-MnO2
• Analysis of structural changes and manganese dissolution during electrochemical tests
• Evaluation of H+/Zn2+ intercalation and overall electrochemical performance.
• Mo/N co-doping suppresses manganese dissolution and structural degradation
• Enhanced H+/Zn2+ intercalation observed
• Overall electrochemical performance improved.
