| Abstract: | Nanosize LiCoO 2 was synthesized by sol gel method, characterized and tested by XRD, TG DTA, BET and ICP measurements. The sample sized in ca. 30 nm with low impurity was obtained. Their electrochemical behavior have been studied by constant current charge/discharge, cyclic voltammetry and AC impedance techniques. The results show that the nanosize LiCoO 2 has a larger initial discharge capacity, better cyclic stability and higher discharge voltage than common LiCoO 2. The mixture of nano LiCoO 2 with common LiCoO 2 in optimum weight ratio showed an improved cyclic stability. |
