Abstract
A process for producing electrode materials, which comprises treating a mixed oxide which comprises lithium and at least one transition metal as cations with at least one oxygen-containing organic compound of sulfur or phosphorus or a corresponding alkali metal or ammonium salt of an oxygen-containing organic compound of sulfur or phosphorus, or a fully alkylated derivative of an oxygen-containing compound of sulfur or phosphorus.

A process for producing electrode materials, which comprises treating a mixed oxide which comprises lithium and at least one transition metal as cations with at least one oxygen-containing organic compound of sulfur or phosphorus or a corresponding alkali metal or ammonium salt of an oxygen-containing organic compound of sulfur or phosphorus, or a fully alkylated derivative of an oxygen-containing compound of sulfur or phosphorus.
An electrode material comprising at least one mixed oxide of the general formula (I)
- LizMxOy (I)
- in which the variables are each selected as follows:
- M is one or more metals of groups 3 to 12 of the Periodic Table of the Elements,
- x is in the range from 1 to 2,
- y is in the range from 2 to 4,
- z is in the range from 0.5 to 1.5,
- modified within the range from 0.02 to 1% by weight, based on the mixed oxide, of P in the +3 or +5 oxidation state.
