摘要：

This study investigated the effects of the concentrations of LiNO3 aqueous electrolytes on the initial electrochemical properties of LiNiO2 (LNO) electrodes. Electrochemical measurements revealed that the properties of LNO were improved in terms of charge/discharge capacities, Coulombic efficiency, and reversibility in a saturated LiNO3 solution during the initial cycles. In addition, in situ X-ray diffraction indicated that the electrochemical improvement was directly related to the recovery rate of the volume of LNO during the first charge/discharge.
