Abstract

The study on the influences of ZrO₂ addition in LiMn₂ O₄ thin films as cathodes was driven by the need to improve the physical and electrochemical performances of thin-film lithium batteries. The films of x ZrO₂ - LiMn₂ O₄ at x=0.025 possessed a high capacity retention of > 82% at 4C after 130 cycles, compared to 68% at x=0, due to the formation of amorphous ZrO₂ on the grain boundary and surface out of the LiMn₂ O₄ matrix via the pulsed laser deposition. The ZrO₂ modification decreased the charge-transfer resistance (Rct) and unwanted phase transition of the LiMn₂ O ₄ cathode film.
