Synthesis and high rate properties of nanoparticled lithium cobalt oxides as the cathode material for lithium-ion battery
2002
Nanoparticled lithium cobalt oxides were synthesized by coprecipitation in ethanol. Mechanical stirring was used to control the particle growth. The controlled grain size was below 100 nm with a narrow distribution. The structure has been examined using X-ray diffraction. On hand of an experimental cell it appears that the novel material has an exciting high charge and discharge rate: the capacity is 100 mA h/g for a 50C rate and 130 mA h/g for a 10C rate.
