Lithium-ion battery (LIB) is one of rechargeable battery types in which lithium ions move from the negative electrode (anode) to the positive electrode (cathode) during discharge, and back when charging.

Developing active materials for the positive electrode is important for enhancing the energy density. Generally, Co-based active materials, including LiCoO 2 and Li (Ni 1–x–y Mn x Co y)O 2, are widely used in positive electrodes. However, recent cost trends of these samples require Co-free materials.
For positive electrode materials, in the past decades a series of new cathode materials (such as LiNi 0.6 Co 0.2 Mn 0.2 O 2 and Li-/Mn-rich layered oxide) have been developed, which can provide a capacity of up to 200 mAh g −1 to replace the commercial LiCoO 2 (∼140 mAh g −1).
Clearly, the electrochemical properties of these electrode materials (e.g., voltage, capacity, rate performance, cycling stability, etc.) are strongly dependent on the correlation between the host chemistry and structure, the ion diffusion mechanisms, and phase transformations. 23
