Synthesis of LiCoO2 starting from carbonate precursors II. Influence of calcination conditions and leaching

Abstract The effect of initial Li:Co ratio, calcination atmosphere, temperature, leaching in H 2 O or acetic acid solution on reaction completeness, final Li:Co ratio, primary particle size, conductivity and its sensitivity to different atmospheres has been investigated. The calcination gas composition was found to be very important. A powder with a primary particle size of 100–300 nm and with less than 3 wt.% of unreacted Li 2 CO 3 was obtained.
