![]() ![]() ![]() Moreover, the energy storage mechanism of NCMO is investigated to elucidate the reversible insertion/extraction of H+ and Zn2+ in δ-MnO2 during charge/discharge processes. NCMO exhibits enhanced energy storage capacity and ultrafast ion diffusion kinetics. The experimental results further demonstrate the success of the strategy. ![]() The ordered nanostructure endows NCMO with uniform and lower stress distributions at various current densities, as evidenced via finite-element simulations. This paper combines atomic modification and structure engineering strategy for fabricating nickel and cobalt-modified δ-MnO2 (NCMO) as the cathode material for ZIBs. The electrochemical performance of manganese dioxides in aqueous zinc-ion batteries (ZIBs) is still impeded by inferior conductivity and sluggish chemical kinetics. ![]()
