A New Technique for Preparation of the Cathode Material of Lithium-ion Battery

Abstract

Abstract:

The cathode material LiCoO₂ of lithium-ion batteries can be obtained from the reaction of LiOH·H₂O and Co(OH)_2-2xR_x(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.

Key words: Lithium-ion battery, Cathode material, LiCoO₂
