Abstract

Lithium cobalt oxide (LiCoO₂) was synthesized by carbon combustion synthesis (CCS) using carbon as fuel. X-ray diffraction (XRD) and scanning electron microscope (SEM) measurements showed that carbon combustion led to the formation of layered structure of LiCoO₂ and the particle size could be controlled by carbon content. For the LiCoO₂ sample prepared at 800 °C for 2 h, at molar ratio of C/Co = 0.5, the particle-size distribution fell in the narrow range of 3–5 μm. Electrochemical tests indicated this LiCoO₂ sample delivered an initial discharge capacity of 148 mAh/g with capacity retention rate higher than 97% after 10 cycles.
