Figure 6

Calculation results of the activation barriers in lithium vacancy environments. (a) Energy profiles for Li diffusion and diffusion path in LiNi0.8Co0.2O2, (b) energy profiles for Li diffusion in LiNi0.8Co0.2O2 with 4.17% Li-Ni exchange and diffusion path under Ni ion, (c) energy profiles for Li diffusion in LiNi0.8Co0.2O2 with 4.17% Li-Ni exchange and diffusion path under Li ion. Squares are lithium vacancies, black arrows represent diffusion path, and the blue double-sided arrows represent Li-Ni exchange.
