Abstract

LiCoO₂ single-crystal particles were obtained by supercritical water synthesis (SCWS) under optimized preparation conditions. The reaction time was less than 1 min. The LiCoO₂ particle size was <1 μm, which was much smaller than that of LiCoO₂ prepared by a solid-state reaction, and the LiCoO₂ crystal shape was rhombohedral. An electron diffraction image showed a highly crystalline LiCoO₂ phase. Intercalation and deintercalation of lithium into and from LiCoO₂ particles were carried out with good reversibility.
