ELECTRODES AND ELECTRODE MATERIAL FOR LITHIUM ELECTROCHEMICAL CELLS

摘要

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 D5o ranging from 1.5µm and 3µm, a D10 = 0.5µm, a D90 =10.0 µm, and a calculated ratio (D90 / D 10) / 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.
