Claims20
Carbon-containing composite material containing particles of an oxygen-containing lithium transition metal compound which are covered in areas with two carbon-containing layers.
Composite material according to 1, wherein the carbon in each carbon-containing layer has a different structure in the solid.
Method for producing a composite material according to one of the previous claims, comprising the steps of:
- a) providing an oxygen-containing lithium transition metal compound in particle form;
- b) adding a precursor compound of pyrolytic carbon and producing a mixture of the two components;
- c) reacting the mixture by heating;
- d) adding a new precursor compound of pyrolytic carbon to the reacted mixture and producing a second mixture;
- and
- e) reacting the second mixture by heating.
