PROCESS FOR PREPARING CATHODE MATERIAL FOR LITHIUM BATTERIES

摘要

The present invention relates to a novel process based on solid state thermal reaction for the preparation of cathode materials for lithium secondary batteries such as rocking chair and intercalated batteries. The solid state reaction takes place between solid lithium oxide (Li20) and a metal compound selected from oxides and nitrates. The metal is selected from nickel and cobalt. Urea or ammonium nitrate may be added to the reaction mixture in order to generate heat. LiNiO2 and LiCoO2 are formed.
