The cathode material LiCoO2 of lithium-ion batteries can be obtained from the reaction of LiOH·H2O and Co(OH)2-2xRx(R is the inorganic or organic acid radicals), which is the midst product of the electrolysis of the metal cobalt in a given electrolyte. The achieved cathode material LiCoO2 for lithium-ion batteries has a single phase and its granularity distribution relatively concentrates through the experiments of XRD, SEM and Laser Granularity Testing. The discharge capacity is relatively high which reaches 146mAh/g at the first time of discharging and still maintains 142mAh/g after 10 cycles of charge/discharge experiments. The cost for the preparation of the cathode material LiCoO2 can greatly be decreased through this technique, which has a well-promising application future.
