Efficacy of atomic layer deposition of Al₂O₃ on composite LiNi_0.8Mn_0.1Co_0.1O₂ electrode for Li-ion batteries.

ABSTRACT: LiNi_0.8Mn_0.1Co_0.1O₂ (NMC811) is a popular cathode material for Li-ion batteries, yet degradation and side reactions at the cathode-electrolyte interface pose significant challenges to their long-term cycling stability. Coating LiNi_xMn_yCo_1-x-yO₂ (NMC) with refractory materials has been widely used to improve the stability of the cathode-electrolyte interface, but mixed results have been reported for Al₂O₃ coatings of the Ni-rich NMC811 materials. To elucidate the role and effect of the Al₂O₃ coating, we have coated commercial-grade NMC811 electrodes with Al₂O₃ by the atomic layer deposition (ALD) technique. Through a systematic investigati
