Abstract

The present invention concerns specific new compounds of formula Li (2−x) Na (x) MO (2−y/2) F (1+y) (where 0≤x≤0.2 and −0.6≤y≤0,8 and M is a transition metal), cathode material comprising the new compounds, batteries and lithium-cells comprising said new compound or cathode material, a process for the production of the new compound and their use.

Claims (20)

1. A compound of formula Li (2−x) Na x MO (2−y/2) F (1+y) , wherein M represents one or more of V, Mo, Cr, and W and 0≤x≤0.2 and −0.6<y<0.8.

2. The compound of claim 1 , wherein x =0 and/or y =0.

3. The compound of claim 1 , wherein x =0.1 and/or y =0.

4. The compound of claim 1 , wherein M is in a trivalent oxidation state.

5. The compound of claim 1 , wherein M represents V.

6. The compound of claim 1 , wherein M represents Cr.
