Patent number: 7993621Abstract: The present invention relates to the physical or chemical specific purification of natural mineral graphite. This purification is preferably applied to the surface of natural graphite in order to allow the formation of a passivation film during the first electrical discharge or the insertion of lithium in the graphite when the latter is used in a lithium-ion cell. The grinding to a small size before purification allows the optimization of the distribution of the particles, resulting in a more uniform electrode. This grinding is carried out in the presence of the natural impurities of the graphite that play the role of a micro-abrasive and result in a hardness of the graphite that increases its mechanical properties.Type: GrantFiled: April 23, 2007Date of Patent: August 9, 2011Assignee: Hydro-QuebecInventors: Karim Zaghib, Michel Gauthier, Gabrielle Nadeau, Abdelbast Guerfi, Monique Massé, Fernand Brochu, Michel Armand

Publication number: 20110108771Abstract: A composition for applying a coating on a support at low temperature from a dispersion of at least a component of the coating to be deposited in the composition. The composition includes at least a strong and heavy solvent with a boiling point higher than 150° C. approximately, and a weak solvent with a boiling point less than 100° C. approximately. The solvents forming the composition must constitute a mixture that evaporates at a temperature less than 100° C. The composition is particularly useful for forming electrodes or electrolyte in lithium-ion batteries. The method and the device used for forming the coating use a dispersion spreader and an infrared lamp.Type: ApplicationFiled: November 12, 2010Publication date: May 12, 2011Applicant: HYDRO-QUEBECInventors: Abdelbast GUERFI, Fernand Brochu, Monique Masse, Karim Zaghib
