Solvent, Concentration and Temperature Effects in LiNi0.5Mn1.5O4‐Li3PO4 Coating Processes
Batteries &Supercaps, EarlyView.In this study, the utilization of hydrogen peroxide (H2O2) as an activating agent is employed to enhance the electrochemical properties of spinel LiNi0.5Mn1.5O4 by coating it with Li3PO4. The coating process is straightforward and can be accomplished in either organic or aqueous media.
