Figure 7

Calculation results of the activation barriers in Li-Ni exchange environments. (a) Calculated activation barrier for Li migration with different Li-Ni exchanges under Li or Ni ion, (b) charge distribution for Li diffusion in LiNi0.8Co0.2O2 without Li-Ni exchange, (c) charge distribution for Li diffusion in LiNi0.8Co0.2O2 with 4.17% Li-Ni exchange and diffusion path under Ni ion, and (d) charge distribution for Li diffusion in LiNi0.8Co0.2O2 with 4.17% Li-Ni exchange and diffusion path under Li ion.
