Publication number: 20100035150Abstract: An electrode laminate unit of an electric storage device includes positive electrodes, negative electrodes and a lithium electrode connected to the negative electrode. When an electrolyte solution is injected into the electric storage device, lithium ions are emitted from the lithium electrode to the negative electrode. A positive and a negative electrode current collector have through-holes that guide the lithium ions in the laminating direction. The aperture ratio of the through-holes at the edge parts where the electrolyte solution is easy to be permeated is set to be smaller than the aperture ratio at central parts in order to suppress the permeation. Thus, the distribution of the electrolyte solution is made uniform, whereby the doping amount is made uniform.Type: ApplicationFiled: July 21, 2009Publication date: February 11, 2010Applicant: Fuji Jukogyo Kabushiki KaishaInventors: Nobuo Ando, Mitsuru Nagai, Takashi Utsunomiya, Ken Baba
