Lithium compounds LiCoO

The high cost and toxicity of cobalt compounds has prompted a search for alternative materials that intercalate lithium ions. Examples of these are LiMn204 [iv], LiCoo.2Nio.8O2. LiNio.5Mni.504 [v], LiNio.5Mno.5O2 [vi], LiFeP04 [vii], Lix VO [viii], and LixMrVOz (M = Ca, Cu) [ix], etc. 

Toda Kogyo Corporation is promoting the development for each cathode material for lithium-ion batteries depending on their use for example, LiCoO for notebook personal computers and cellular phones LiMn O for hybrid electric vehicles (HEV) and LiNiO for high-capacity batteries. Special efforts are being made in the improvement of the above problems, i.e., cycle characteristics and thermal stability, for LiNiOj, so that this compound can be included in the market trend of lithium ion batteries. This chapter presents the results of the process development to improve the above-mentioned problem.
