Abstract
The electrochemical characteristics of high-temperature (HT) LiCoO2 (9 00 degrees C) and low-temperature (LT) LiCoO2 (450 degrees C) were stu died. From cyclic voltammetry results, lithium intercalating into LT-L iCoO2 generates two current peaks at 3.8 and 3.3 V, respectively, whic h is contrast to the intercalation of lithium into HT-LiCoO2. The resi stance of lithium extraction is smaller than that of lithium insertion . The diffusion coefficients of Li+ ions in LiCoO2 have an order of 10 (-9) cm(2)/s.
