Abstract :
The solubility of LiCoO2 was proportional to Pco2 3/2 and Po2-1/4 in (Li0.52 Na0.48)2CO3. It obeys the acidic dissolution mechanism. This result was the same dependence as that in (Li0.62K0.38)2CO3. The solubility of LiCoO2 in (Li0.52Na0.48) 2CO3 was about a half of that in (Li0.62K0.38)2CO3. The solubility of LiCoO2 decreased with Li content in Li-K carbonate system. The solubility of LiCoO2 was lower than that of NiO even under the pressurized cathode condition of MCFC
