Verfahren zur Herstellung eines kathodischen Materials für einen sekundären Generator mit Lithiumanode und Anwendung dieses Materials

摘要

Process for the manufacture of a cathodic material for a secondary generator with a lithium anode, a material satisfying one of the formulae LiyNi2-y O2 and LiNi1-x Cox O2, characterised in that, y being chosen between 0.84 and 1.22, and x being chosen between 0.09 and 0.5, starting from lithium hydroxide, nickel oxide, and possibly cobalt oxide, in pulverised form in the desired stoichiometric ratio, it is heated in air to a temperature lying between 600 DEG C and 800 DEG C approximately.
