PROCESS FOR THE PREPARATION OF FINELY DISPERSED LITHIUM TITANIUM SPINELS AND THEIR USE

摘要

The present invention relates to a method for producing a mixture for generating lithium titanium spinel Li4Ti5O12, comprising the step of mixing Li2CO3 and TiO2 in a container (1), in which at least one elongate element (2) having a first end (2a) and a second end (2b) is arranged such that the first end (2a) is directed toward an inside wall (1a) of the container (1), and is spaced apart therefrom by a distance d. The step of mixing is carried out by means of allowing the container (1) to rotate and maintaining the elongate element (2) in position, such that a relative movement takes place between the inside wall (1a) of the container (1) and the first end (2a) of the elongate element (2), wherein the distance d is kept constant during the mixing process. The invention further relates to a method for producing lithium titanium spinel Li4Ti5O12 from a mixture produced in this way, and to the use thereof as anode material in rechargeable lithium ion batteries.
