摘要：

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 Xray 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.
