Abstract

Ni-rich layered oxide cathodes are facing a fundamental challenge of loss in performance as a result of air storage, hampering their practical application in lithium-ion batteries. We present here an investigation of extended air storage and a solution to overcome the chemical instability by coating the Ni-rich layered oxide with a Mn-based spinel oxide.
