An Oxygen-Scavenger Sulfide Coating Enabling Long-Term Stable Nickel-Rich Cathodes.

ABSTRACT: Oxygen release is a major issue associated with layer-structured metal oxide cathodes in lithium batteries, which can further cause a series of problems, such as irreversible phase transition, microcracking, and electrolyte decomposition. Eventually, these issues jointly result in cell performance degradation and safety hazards. Thus, it is very significant to tackle oxygen release for achieving long-term stable cyclability, but very challenging. Although intensive efforts have been invested to date, there still lacks a feasible solution. In this study, nanoscale ZrS₂ coatings are applied on prefabricated LiNi_0.8Mn_0.1Co_0.1O₂ (NMC811) cathodes directly via atomic layer deposition (ALD). Very encouragingly, we reveal that this ALD-deposi
