Publication number: 20090183650Abstract: Several synthetic additives have been used to improve the carbon coatings on LiFePO4 electrode materials. Pyromellitic acid (PA) added prior to calcination decreases the D/G ratios of the carbon produced in situ, while the use of both iron nitrate and PA results in increased sp2 character. Thus, the carbon coatings are structured with a greater fraction of graphitic character. The production of structured carbon coatings results in higher pressed pellet conductivities of LiFePO4/C composites and improved electrochemical performance of cells containing these cathode materials, although the carbon content is not necessarily increased. The combination of both ferrocene and PA used during LiFePO4 synthesis causes more carbon to be retained, although the structural characteristics are similar to that produced from the same amount of PA alone.Type: ApplicationFiled: June 12, 2007Publication date: July 23, 2009Applicant: The Regents of the University of CaliforniaInventors: Marca M.

Patent number: 7198666Abstract: A coating film is formed on a substrate of sapphire by coating the substrate with a jointing material prepared by dissolving Al(OC2H5)3 and B(OCH3)3 into xylene. Subsequently, the substrate is heated to about 450 ° C. and the coating film is irradiated with, e.g., ultraviolet radiation having a wavelength of 172 nm. Thus, xylene in the coating film is vaporized, and Al(OC2H5)3 and B(OCH3)3 are thermally decomposed to form a jointing material composed of amorphous or ?-layer alumina (Al2O3) and amorphous boron oxide (B2O3).Type: GrantFiled: October 25, 2001Date of Patent: April 3, 2007Assignee: Yamatake CorporationInventor: Takashi Masuda
