Graphite insertion compounds having improved properties and electrochemical applications of these compounds

摘要

The invention relates to insertion compounds having improved properties for electrochemical applications. They are characterised in that they are obtained from a graphite which has a specific surface of at least 100 m2/g and a particle size of not more than 4 mu m. First stage NiCl2/graphite or graphitic oxide obtained from such a graphite and used as constituent of the cathode of a lithium battery gives excellent characteristics to the latter. Application: constituent of electrodes for electrochemical generators, especially for lithium batteries.
