Electrochemical properties of Li2O-2B2O3 glass-modified LiMn2O4 powders prepared by spray pyrolysis process

► Li2O-2B2O3 glass-modified LiMn2O4 cathode powders with fine size and spherical shape are prepared by spray pyrolysis process. ► The LBO glass material covering the LiMn2O4 powders improves the electrochemical properties of the powders. ► The discharge capacity of the LiMn2O4 powders with glass material decreases from 131.0 to 113.2 mAh g−1 after 100 cycles.
