Abstract
Lithium cobaltate (LiCoO2) of stoichiometric composition was synthesized by an improved sol-gel method combined with a solid-state method. Originality of this paper is that, cobalt oxidation is used not by long-term high temperature treatment, but by bubbling with air oxygen (Co2+→Co3+) during sol-gel synthesis. A fundamental schematic diagram of the synthesis has been developed based on experimental results. The electrophysical properties of lithium cobaltate were determined (electronic ionic conductivity) and physical properties (particle size, specific surface area). The optimal synthesis parameters were established.
