TITANIUM AND DENSE LITHIUM MIXED OXIDE POWDER COMPOUND, METHOD FOR PRODUCING SAID COMPOUND AND COMPOUND-CONTAINING ELECTRODE

摘要

The inventive titanium and lithium mixed oxide powder compound, preferably usable in the form of an electrode active material for a lithium battery consists of particles (1) whose diameter is equal to or less than 1µm and at least of 10 % by volume of grains (2) whose diameter is equal to or less than 100µm and which are formed by agglomerating said particles (1). The method for producing the inventive compound preferably consists in grinding a synthesised oxide for a time ranging from 24 to 48 hours in a planetary mill and in carrying out a heat treatment at a temperature ranging from 4500 to 6000 °C.
