Abstract
Improving the stability of Ni-rich cathode materials for lithium-ion batteries is crucial for improving their overall performance. Herein, the electrochemical performance of F-doped Li(Ni0.8Co0.1Mn0.1)O2 was investigated. Analysis of the calculations shows that F-doping contributes to electron transport, intercalation potential, and cycling stability, but it is detrimental to the diffusion of lithium ions. This theoretical research provides insight into the microscopic mechanism of F-doping to enhance the cycling stability of Ni-rich cathode materials and is a necessary supplement to experimental study.
