ABSTRACT:
The invention concerns a process for producing a spinel compound of formula Li4Ti5O12, comprising a step of preparing a mixture of an organo-lithium compound selected from lithium alcoholates with an organo-titanium compound selected from titanic acid esters, in a liquid medium, and a step of hydrolyzing the mixture of said compounds. The invention also concerns a Li4Ti5O12particulate material which may be produced according to the previous cited process and which has a BET surface area of at least 10 m2/g. The material is particularly useful in the manufacture of Lithium Ion batteries.
