The magnetic properties and structure of Li x Co O 2 for 0.5< x< 1.0 are reported. Co 4+ is
found to be high spin in Li x Co O 2 for 0.94⩽ x⩽ 1.00 and low spin for 0.50⩽ x⩽ 0.78. Weak …

Angular-dependent core hole screening effects have been found in the cobalt K-edge x-ray
absorption spectrum of LiCoO 2, using high-resolution data and parameter-free general …

We report a novel delithiation process for epitaxial thin films of LiCoO2 (001) cathodes using
only physical methods, based on ion sputtering and annealing cycles. Preferential Li …

The electronic properties of LiCoO 2 have been studied by theoretical band-structure
calculations (using density functional theory) and experimental methods (photoemission) …

Increasing the charging voltage to 4.6 V directly enhances battery capacity and energy
density of LiCoO2 cathodes for lithium-ion batteries. However, issues of the activated …

Lithium-ion deintercalation/intercalation during charge/discharge processes is one of the
essential reactions that occur in the layered cathodes of lithium-ion batteries, and the …
