LI4TI5O12, LI(4-.ALPHA.)Z.ALPHA.TI5O12, OR LI4Z.BETA.TI(5-.BETA.)O12 PARTICLES, METHODS FOR OBTAINING SAME AND USE AS ELECTROCHEMICAL GENERATORS

摘要

Process for the synthesis of Li4Ti5O12, Li4Z .beta particles T i (5-.beta.) O12 or Li (4-.alpha.) Z.alpha. Ti5O12, preferably of spinel structure, in which .beta. is greater than 0 and less than or equal to 0.5 (preferably of spinel structure), .alpha. representing a number greater than 0 and less than or equal to 0.33, Z representing a source of at least one metal selected from the group consisting of Mg, Nb, Al, Zr, Ni and Co. These carbon-coated particles exhibit especially electrochemical properties of particular interest as a component of the anode and / or the cathode of electrochemical generators.
