Patent number: 8697025Abstract: In the raw coke composition of the invention, as the starting material for a negative electrode material of a lithium ion secondary battery, the ratio of the crystallite size Lc(002) and lattice constant co(002) (Lc(002)/co(002)) on the 002 plane is no greater than 180, and the ratio of the crystallite size La(110) and the lattice constant ao(110) (La(110)/ao(110)) on the 110 plane is no greater than 1500, as determined by X-ray diffraction upon graphitizing in an inert gas atmosphere at a temperature of 2800° C.Type: GrantFiled: November 6, 2008Date of Patent: April 15, 2014Assignee: JX Nippon Oil & Energy CorporationInventors: Tamotsu Tano, Takashi Oyama, Hiromitsu Hashisaka, Akio Sakamoto

Patent number: 8226921Abstract: The present invention provides a raw coke having such a structure that the graphitized product resulting from graphitization of the raw coke at a temperature of 2800° C. under an inactive gas atmosphere will have ratios of the crystallite size to the lattice constant of 360 or less in the (002) plane and 1500 or less in the (110) plane, as a raw coke providing active carbon produced by alkali-activating the raw coke, which is reduced in remaining alkali content and can simplify washing operation because washing liquid can easily pass through the activated carbon, or as a raw coke for the production of needle coke.Type: GrantFiled: June 10, 2011Date of Patent: July 24, 2012Assignees: Nippon Oil Corporation, Nippon Petroleum Refining Company, LimitedInventors: Takashi Oyama, Kazuhisa Nakanishi, Tamotsu Tano, Keiji Higashi, Ippei Fujinaga, Hiromitsu Hashisaka, Toshitaka Fujii, Takashi Noro, Akio Sakamoto, Kiwamu Takeshita, Keizou Ikai, Masaki Fujii, Hideki Ono
