In situ inorganic conductive network formation in high-voltage single-crystal Ni-rich cathodes
Abstract
Single-crystal Ni-rich cathodes suffer from side reactions with the electrolyte and slow Li-ion transport during high-voltage cycling. Herein, a Li1.4Y0.4Ti1.6(PO4)3 coating is applied to facilitate the Li-ion transport and improve the cycling life of the cell.
