20140106223 | METHODS FOR SURFACE COATING OF CATHODE MATERIAL LiNi0.5-XMn1.5MXO4 FOR LITHIUM-ION BATTERIES - A high-voltage lithium-ion battery cathode material includes LiNi | 04-17-2014 |
20140105811 | SUPERCRITICAL CONTINUOUS HYDROTHERMAL SYNTHESIS OF LITHIUM TITANATE ANODE MATERIALS FOR LITHIUM-ION BATTERIES - A method for synthesizing lithium titanate includes preparing a supercritical fluid from water; reacting a solution containing lithium and titanium with the supercritical fluid under a condition that maintains the supercritical fluid in its supercritical state to produce a reaction mixture comprising the lithium titanate; and collecting the lithium titanate. The supercritical fluid is prepared at a temperature of 375-500° C. and a pressure of 22-35 MPa. The solution containing lithium and titanium is prepared by mixing a solution containing lithium, prepared by dissolving a lithium source in a selected solvent, and a solution containing titanium, prepared by dissolving a titanium source in the selected solvent, wherein a molar ratio of lithium:titanium is between 4.0:5.0 and 4.5:5.0. The lithium source is lithium hydroxide, lithium carbonate, lithium acetate, lithium oxalate, lithium nitrate, or lithium oxide, and the titanium source is tetrabutyl titanate. | 04-17-2014 |
