Abstract:<\/h4>\n
LiNi0.8<\/sub>Mn0.1<\/sub>Co0.1<\/sub>O2<\/sub> (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 LiNix<\/sub>Mny<\/sub>Co1-x-y<\/sub>O2<\/sub> (NMC) with refractory materials has been widely used to improve the stability of the cathode-electrolyte interface, but mixed results have been reported for Al2<\/sub>O3<\/sub> coatings of the Ni-rich NMC811 materials. To elucidate the role and effect of the Al2<\/sub>O3<\/sub> coating, we have coated commercial-grade NMC811 electrodes with Al2<\/sub>O3<\/sub> by the atomic layer deposition (ALD) technique. Through a systematic investigation of the long-term cycling stability at different upper cutoff voltages, the stability against ambient storage, the rate capability, and the charger transfer kinetics, our results show no significant differences between the Al2<\/sub>O3<\/sub>-coated and the bare (uncoated) electrodes. This highlights the contentious role of Al2<\/sub>O3<\/sub> coating on Ni-rich NMC cathodes and calls into question the benefits of coating on commercial-grade electrodes.<\/p>\n","protected":false},"excerpt":{"rendered":"DOI: 10.1038\/s41598-024-69330-6 Authors: Heran Huang, Linna Qiao, Hui Zhou, Yalun Tang, Matthew J.
