Insights into the role of the covalent Ni–O bonds in LiNiO<sub>2</sub> positive electrodes: a correlative hard X-ray spectroscopy study
Representative NiO 2 layers composed of edge-sharing NiO 6 octahedra and a Li interlayer from the LiNiO 2 crystal structure, highlighting a local NiO 6 unit. A simplified band diagram illustrates the negative charge transfer from O 2p to Ni 3d states.
