Lithium cobalt oxide (LiCoO 2) is an irreplaceable cathode material for lithium-ion batteries with high volumetric energy density. The prevailing O 3 phase LiCoO 2 adopts the ABCABC (A, B, and C stand for lattice sites in the close-packed plane) stacking modes of close-packed oxygen atoms.
The manipulation of cobalt-ion sites through partial replacement by atoms (e.g., zirconium (Zr), aluminium (Al), and vanadium (V)) is considered to be a feasible strategy that has been widely demonstrated to enhance the electrochemical performance of LCO, especially under high-voltage or high-rate conditions , , , .
It is generally accepted that—except for related issues caused by residual lithium compounds on the electrode surface—other factors such as the oxidization and dilution of cobalt ions stem from the unstable/irreversible evolution of the lattice oxygen.
Hence, all the materials are not applicable for practical usage. Among the above-mentioned materials, layered lithium nickel cobalt manganese oxide (LiNi x Mn y Co 1−x−y O 2: NCM), specifically LiNi 1/3 Co 1/3 Mn 1/3 O 2 (NCM111), is widely exploited for commercial LIB applications.
In O 2 –LCO, Li + diffusion is faster, and the elasticity change is continuous, all of which slows down the internal stress rise and benefits high-voltage cycling stability.
The electronic conductivity of Li x CoO 2 was initially found to vary from semiconductive (x = 1) to metallic (x = 0.9–1.0) with the extraction of Li +, which is further enhanced as the process continues, favoring the Li + transferal process (Fig. 3 (b)) , .
