Abstract
The invention relates to a process for the preparation of ternary lithium spinels, and to ternary lithium spinels of the general formula Li.sub.a Me.sub.b Mn.sub.2-b O.sub.c. The invention is achieved in accordance with the invention by a process which comprises dissolving a manganese salt in water, adding an oxidant, adding the mixture to an aqueous lithium hydroxide solution containing from 0.1 to 1 % by weight, based on the content of LiOH employed, of seed crystals selected from the group consisting of activated carbon, Aerosil and spine, and separating off, washing and heating the precipitate.
