Patent number: 9457512Abstract: 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: GrantFiled: July 1, 2013Date of Patent: October 4, 2016Assignee: NAMICS CORPORATIONInventors: Mamoru Baba, Shoichi Iwaya, Hitoshi Masumura, Noriyuki Sakai, Takayuki Fujita, Hiroshi Sasagawa, Hiroshi Sato

Patent number: 9236594Abstract: 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: GrantFiled: February 16, 2007Date of Patent: January 12, 2016Assignee: NAMICS CORPORATIONInventors: Shoichi Iwaya, Hitoshi Masumura, Noriyuki Sakai, Takayuki Fujita, Hiroshi Sasagawa, Hiroshi Sato
