In this study, we synthesize V5+-doped LiNi0.5Mn1.5O4 (LNMO) and subject it to SiO2 surface modification using a coprecipitation method. The synergistic effect of ion doping and interfacial engineering improves the electrochemical properties of LNMO by accelerating its redox kinetics and prolonging...
