Publication number: 20140015173Abstract: Conventional ion rechargeable batteries having an electrode layer on an electrolyte layer suffer from an impurity layer formed at the interface, degrading performance. Conventional batteries with no such impurity layer have a problem of weak interface bonding. In the present invention, in a baking process step after an electrode layer is laminated on an electrolyte layer, materials for an electrode layer and an electrolyte layer are selected such that an intermediate layer formed of a reaction product contributing to charging and discharging reactions is formed at the interface of the electrode layer and the electrolyte layer. In addition, a paste that an active material is mixed with a conductive material at a predetermined mixing ratio is used to form a positive electrode layer and a negative electrode layer. Reductions in electrode resistance and interface resistance and improvement of charging and discharging cycle characteristics are made possible.Type: ApplicationFiled: July 1, 2013Publication date: January 16, 2014Inventors: Mamoru BABA, Shoichi IWAYA, Hitoshi MASUMURA, Noriyuki SAKAI, Takayuki FUJITA, Hiroshi SASAGAWA, Hiroshi SATO

Publication number: 20100075219Abstract: In multilayer wholly solid lithium ion secondary batteries, a laminate having a collector layer of material with high conductivity superimposed on an active material layer has been disposed so as to attain a lowering of battery impedance. Consequently, in the fabrication of each of positive electrode layer and negative electrode layer, stacking of three layers consisting of an active material layer, a collector layer and an active material layer has been needed, thereby posing the problem of complex processing and high production cost. In the invention, a positive electrode layer and a negative electrode layer are fabricated from paste consisting of active material mixed with conductive substance in a given mixing ratio, and no collector layer is disposed. This realizes process simplification and manufacturing cost reduction without deterioration of battery performance and has also been effective in enhancing of battery performance, such as improvement to cycle characteristics.Type: ApplicationFiled: February 16, 2007Publication date: March 25, 2010Applicant: NAMICS CORPORATIONInventors: Shoichi Iwaya, Hitoshi Masumura, Noriyuki Sakai, Takayuki Fujita, Hiroshi Sasagawa, Hiroshi Sato, Hisao Fukumori

Patent number: 7306296Abstract: A failure check apparatus for a control apparatus of a vehicle such as ABS. When the failure check apparatus performs initial check for the ABS, it successively activates each of solenoid valves and a motor provided in the ABS, one at a time, for a predetermined time so as to determine whether a failure has occurred in the ABS. At that time, activation of the motor is started when a certain delay time elapses after the end of activation of the last solenoid valve. The delay time is a time which the vibration generated in the control apparatus upon activation of the last solenoid valve converges. Thus, interference between a vibration wave (sound wave) generated upon actuation of the solenoid valves and a vibration wave (sound wave) generated upon actuation of the motor, which differ in nature of vibration, is prevented.Type: GrantFiled: December 16, 2004Date of Patent: December 11, 2007Assignees: Advics Co., Ltd., Mitsubishi Jidosya Engineering Kabushiki Kaisya, Mitsubishi Jidosya Kogyo Kabushiki KaisyaInventors: Takashi Watanabe, Kenji Fujiwara, Mitsuharu Yokoyama, Kotaro Kajiwara, Hiroyuki Masuda, Noriyuki Sakai
