Lithium cobalt oxide (LCO) is widely used in Li-ion batteries due to its high volumetric energy density, which is generally charged to 4.3 V. Lifting the cut-off voltage of LCO from 4.3 V to 4.7 V will increase the specific capacity from 150 to 230 mAh g -1 with a significant improvement of 53%.
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.
While lithium cobalt oxide (LCO), discovered and applied in rechargeable LIBs first by Goodenough in the 1980s, is the most widely used cathode materials in the 3C industry owing to its easy synthesis, attractive volumetric energy density, and high operating potential [, , ].
A rational compositional design of high-nickel, cobalt-free layered oxide materials for high-energy and low-cost lithium-ion batteries would be expected to further propel the widespread adoption of elec. vehicles (EVs), yet a compn. with satisfactory electrochem. properties has yet to emerge.
To replace the nickel and cobalt, which are limited resources and are assocd. with safety problems, in current lithium-ion batteries, high-capacity cathodes based on manganese would be particularly desirable owing to the low cost and high abundance of the metal, and the intrinsic stability of the Mn4+ oxidn. state.
