Abstract
A process for preparing modified mixed transition metal oxides, which comprises treating a precursor of a mixed oxide which comprises lithium and at least two transition metals as cations with at least one substance which is selected from compounds of phosphorus, silicon, titanium, boron or aluminum having at least one phenoxy or alkoxy group or at least one halogen.

A process for preparing modified mixed transition metal oxides, which comprises treating a precursor of a mixed transition metal oxide which comprises lithium and at least two transition metals as cations with at least one substance which is selected from compounds of phosphorus, silicon, titanium, boron or aluminum having at least one phenoxy or alkoxy group or at least one halogen per mole.
A mixture of oxides, hydroxides, phosphates, carbonates and/or oxyhydroxides, in particulate form, of at least two elements of groups 3 to 12 of the Periodic Table of the Elements, which have been modified with 0.01 to 1% by weight of at least one element selected from Ti and Si in the +4 oxidation state, B and Al in the +3 oxidation state, and P in the +3 or +5 oxidation state.
