Insights into the role of the covalent Ni–O bonds in LiNiO 2 positive electrodes: a correlative hard X-ray spectroscopy study
Year: 2025
Type: article
Abstract: 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.
