Coupled Solid‐State Diffusion of Li+ and O2 − During Fabrication of Ni‐Rich NMC Thin‐Film Cathodes Resulting in the Formation of Inactive Ni2O3 and NiO Phases

Coupled Solid‐State Diffusion of Li+ and O2 − During Fabrication of Ni‐Rich NMC Thin‐Film Cathodes Resulting in the Formation of Inactive Ni2O3 and NiO Phases

Abstract Ni‐rich Li(Ni1−x−yMnxCoy)O2 (NMC) is an attractive cathode material for Li‐ion batteries due to its high practical capacity (>200 mAh g−1). However, it is plagued by stability issues that, over multiple cycles or prolonged storage in air, degrade the material and decreases its electroche...
