Key Points

This research aims to address the issue of storage degradation in nickel-rich cathodes that occurs under humid air conditions.
Utilized solid-state electrolyte coating to improve nickel-rich cathodes affected by storage degradation.
Evaluated the formation of surface lithium impurities and NiO rock-salt phase during storage.
Assessed the performance of treated and untreated cathodes in battery applications.
Coated nickel-rich cathodes showed significantly reduced levels of surface lithium impurities compared to untreated ones.
The solid-state electrolyte coating effectively mitigated the formation of the NiO rock-salt phase, enhancing performance.
Battery tests indicated improved efficiency and longevity for coated cathodes versus uncoated ones.

Implication

Investigates the effect of solid-state electrolyte coating on storage-degraded nickel-rich cathodes, suggesting a viable solution for battery use.

Abstract

Large-scale production of nickel-rich cathodes inevitably results in severe storage degradation (forming surface lithium impurities and NiO rock-salt phase) under humid air conditions that precludes their direct use in battery...
