Mechanical method using an attrition-type mill is a useful method to synthesize LiCoO2 granules consisting of primary nanoparticles without external heating. On the other hand, the heat treatment after synthesis of LiCoO2 granules is needed to improve its electrochemical performances. Here we report the effect of heating temperature on the battery performances of the LiCoO2 granule cathode. By heating the LiCoO2 granules synthesized by mechanical method, the size of primary particles increased with increasing heating temperature from 600℃ to 800℃, whereas the granule structure was maintained. The cathode of LiCoO2 granules heated at 800℃ exhibited the highest discharge capacity at 0.1 C rate. However, in the case of the charge-discharge tests at high rate, the cathode of LiCoO2 granules heated at 700℃ showed a high discharge capacity over 70 mA・h/g. The relationship between the microstructure of LiCoO2 granule and the battery performance was discussed.
