Title: Formation of lithium-cobalt spinel oxide (Li{sub x}Co{sub 3{minus}x}O{sub 4}) by solid-state reaction of a Li{sub 2}CO{sub 3}-Co{sub 3}O{sub 4} powder mixture

The formation of mixed lithium-cobalt spinel oxide Li{sub x}Co{sub 3{minus}x}O{sub 4} by solid-state reaction in air at low temperature between Li{sub 2}CO{sub 3} and Co{sub 3}O{sub 4} in the atomic ratio Li/Co 1.0 has been investigated by DTG, DTA, and X-ray diffraction measurements. Lithiated Co{sub 3}O{sub 4} was formed around 220 C. As at this temperature the diffusion rate of lithium ions into Co{sub 3}O{sub 4} lattice is very low, it can be assumed that only the surface of Co{sub 3}O{sub 4} particles was lithiated. By increasing the temperature above 380 C, LiCoO{sub 2} formation occurred.
