In lithium-ion batteries, Ni-rich single crystal cathode material (Ni> 90%) is a promising
cathode material, but it has not yet been put into commercial application due to defects such …

From Li 2 NiO 3 to high-performance LiNiO 2 cathodes for application in Li-ion and all-solid-state batteries

L Karger, P Henkel, S Murugan, R Zhang… - Chemical …, 2024 - pubs.rsc.org
The synthesis of LiNiO2 (LNO) typically involves oxidizing Ni (II) to Ni (III), thus leading to
NiLi point-defect formation. Here, materials containing Ni (IV) in the form of overlithiated Li1+ …
