Patent number: 9666858Abstract: A negative electrode for a secondary battery according to the present invention has a collector and a negative electrode active material layer formed on a surface of the collector and containing negative electrode active material particles. In the negative electrode active material layer, an insulating material is arranged between the negative electrode active material particles so as not to develop conductivity by a percolation path throughout the negative electrode active material layer. It is possible in this configuration to effectively prevent the occurrence of a short-circuit current due to an internal short circuit and the generation of heat due to such short-circuit current flow in the secondary battery while securing the battery performance of the secondary battery.Type: GrantFiled: May 25, 2011Date of Patent: May 30, 2017Assignee: NISSAN MOTOR CO., LTD.Inventors: Kenji Ohara, Sohei Suga, Yasuo Ohta, Tomoya Kubota, Kazuyuki Sakamoto, Takaaki Abe, Satoru Ichikawa, Kenji Hosaka, Kosuke Hagiyama, Hiroshi Miyakubo

Patent number: 9077040Abstract: To provide a method that is capable of suppressing absorption of lithium ions into the inner portion of a resin collector that is used in a bipolar lithium ion secondary battery. The collector for a bipolar lithium ion secondary battery of the invention has at least two conductive layers. One of the conductive layers that constitute the collector (a first conductive layer) is configured by adding a conductive filler into a base material that contains an imide group-containing resin. The other of the conductive layers that constitute the collector (a second conductive layer) is configured by adding a conductive filler into a base material that contains a polar resin containing no imide group. The collector for a bipolar lithium ion secondary battery is further characterized in that when a bipolar electrode is formed, the first conductive layer is arranged on the positive electrode side.Type: GrantFiled: December 6, 2010Date of Patent: July 7, 2015Assignee: NISSAN MOTOR CO., LTD.Inventors: Takashi Honda, Yasuyuki Tanaka, Shigeo Ibuka, Satoru Ichikawa
