However, OER catalysts derived from LiCoO₂ have faced obstacles such as high overpotential and a complicated preparation process. In this study, the preparation method is adjusted to optimize the synthesis of Li_1-xCoO₂ with a defective structure, resulting in an impressive overpotential of only 290 mV at a current density of 100 mA cm⁻² and a remarkable Tafel slope of 15.2 mV dec⁻¹.

Density functional theory (DFT) calculations reveal that Li defects can influence the d-band center of active Co sites, enhancing the adsorption capabilities of Co sites towards *OOH intermediates and increasing the conductivity of the electrocatalyst during the OER process.
