Patent number: 6432579Abstract: The present invention relates to a process for producing an anode for a secondary battery, which is capable to reduce a contact resistance between a sintered material which contains silicon as an anode active material and a current collector. A binder and a solvent are mixed with a silicon-containing anode material to prepare a slurry. A base material made of a foil or mesh of conductive metal is coated with the slurry, and the solvent is removed to form a coated film. The coated film is sintered in a non-oxidizing atmosphere, thereby integrating a sintered material of the coated film with the base material.Type: GrantFiled: January 27, 2000Date of Patent: August 13, 2002Assignee: Kao CorporationInventors: Ryuichi Tsuji, Kuniyuki Nakanishi, Toru Nishimura, Tadashi Hirabayashi, Atsushi Suzuki

Patent number: 6413672Abstract: The present invention relates to a lithium secondary battery with a cathode and an anode, each electrode containing an active material capable of incorporating and releasing lithium ions. The anode includes a sintered material which contains 50 to 99 % by weight of silicon and 1 to 50% by weight of carbon material, and has an electrical conductivity not less than 1 S/cm. By employing the anode including the sintered material containing silicon as the anode active material and carbon material, an increased packing density of the active material and an increased capacity per volume can be obtained. Furthermore, the anode conductivity of not less than 1S/cm can provide a high capacity and improved cycle property.Type: GrantFiled: September 25, 2000Date of Patent: July 2, 2002Assignee: Kao CorporationInventors: Atsushi Suzuki, Kuniyuki Nakanishi, Ryuichi Tsuji, Toru Nishimura, Tetsuya Kusakabe, Fumihide Shiga, Nobuyuki Isshiki
