Abstract

Ultrathin crystalline ZrO₂ nanofilms have been facilely deposited on LiMn₂O₄ particles at 120 °C using atomic layer deposition. The ZrO₂ coating shows high crystallinity, conformality and homogeneity, which contribute to considerably improved electrochemical performance of LiMn₂O₄ at elevated temperature in lithium-ion batteries.
