Method of producing lithium ion cathode materials

 

A method of producing Liy[NixCo1−2xMnx]O2 wherein 0.025��x��0.5 and 0.9��y��1.3. The method includes mixing [NixCo1−2xMnx]OH2 with LiOH or Li2CO3 and one or both of alkali metal fluorides and boron compounds, preferably one or both of LiF and B2O3. The mixture is heated sufficiently to obtain a composition of Liy[NixCo1−2xMnx]O2 sufficiently dense for use in a lithium-ion battery cathode. Compositions so densified exhibit a minimum reversible volumetric energy characterized by the formula [1833−333x] measured in Wh/L.

Class: 423594400 (USPTO), H01M004/52 (Intl Class)"
