  • Publication number: 20100035150
    Abstract: 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.

  • Publication number: 20090246633
    Abstract: When a layered crystal material of vanadium pentoxide that can be used as a positive electrode active material is manufactured, a sulfur-containing organic material is not used as a raw material in the present invention. Therefore, uncertain adhesion of the sulfur-containing organic material to the layered crystal material is eliminated. The property of the suspension containing a vanadium compound and plural lithium compounds such as lithium sulfide and lithium hydroxide is adjusted by using these lithium compounds. By this adjustment, the pentavalence of the vanadium ions is controlled to be a desired ratio. Consequently, an active material having reproducibility can be manufactured. First discharge energy of a lithium ion secondary battery using the active material can be enhanced.

  • Publication number: 20090246629
    Abstract: In a current collector laminating step, a current-collector laminate unit 30 composed of current-collector materials 31 and 32 and a film material 33 is formed. Resist layers 34 having a predetermined pattern are formed on both surfaces of the current-collector laminate unit 30. An etching process is performed with the resist layers 34 used as a mask, whereby through-holes 20a and 23a are formed on the respective current-collector materials 31 and 32. The resist layers 34 are removed from the current-collector laminate unit 30. Since the etching process is performed on the plural current-collector materials 31 and 32, productivity of an electrode can be enhanced. During the application of the slurry, the film material 33 prevents the leakage of the electrode slurry. Therefore, the current-collector laminate unit 30 can be conveyed in the horizontal direction, whereby the productivity of the electrode can be enhanced.
