Facilitating Lithium-Ion Diffusion in Layered Cathode Materials by Introducing Li+/Ni2+ Antisite Defects for High-Rate Li-Ion Batteries

Figure 5

Structure and diffusion path of Li+ ions of the Ni-rich cathode materials. (a) Layered structure of the Ni-rich cathode materials; the diffusion of Li+ ions under different conditions: (b) without Li/Ni antisite defects, (c) Li ion occupies TM ion sites, (d) Ni2+ occupies Li+ sites; (e) simultaneously with two defects near the diffusion pathway.
