CARBONATE PRECURSORS FOR HIGH LITHIUM AND MANGANESE CONTAINING CATHODE MATERIALS |
摘要 |
A carbonate precursor compound of a lithium manganese based oxide powder for a positive electrode of a rechargeable battery, the oxide having the general formula Li1+vM1−vO2, wherein −0.03≦v≦0.25, wherein M is a composition comprising at least 50 mol % of manganese, and wherein the carbonate precursor compound has a secondary particle size D50 expressed in μm, and a tap density TD expressed in g/cm3, with either ≦TD≦(2.78*D50)/(D50+7.23) and the compound having a particle size distribution having a span S≦1.8 with S=(D90−D10)/D50; or 1≦TD≦(2.78*D50)/(D50+7.50). |
