摘要：
The waste lithium cobalt acid batteries were utilized as raw materials to separate out LiCoO cathode material. Citric 2 acid was used to leach cathode material, and LiCoO leaching solution was electrodeposited to obtain cobalt 2 plating, in the meantime the Li 2+ ions were enriched. The optimized conditions of leaching process are 1,2 mol/L citric concentration and 0,35 mol/L sodium thiosulfate concertation, the leaching efficiency of cobalt and lithium is 97,5 % and 97,0 % respectively. At pH 4, the smooth cobalt coating with fine grains can be obtained on the surface of the stainless-steel cathode.
