Abstract
An electrode and an electrode material for lithium electrochemical cells are disclosed. The electrode material is in powder form and has a particle size distribution wherein the measured particle size distribution of the electrode material has a median size D50 ranging from 1.5 μm and 3 μm, a D10≧0.5 μm, a D90≦10.0 μm, and a calculated ratio (D90/D10)/D50≧3.0 which is indicative of a peak of the measured particle size distribution on the left of the median D50 which improves the loading and energy density of the electrode produced with this electrode material powder.
