摘要： An electric double layer capacitor, including at least one basic cell, an electrode plate, and an outer package which covers the basic cell and the electrode plate in a decompression state. The basic cell may be laminated in its thickness direction to form a layered cell and includes a separator, a pair of polarized electrodes disposed so as to sandwich the separator, a pair of collectors disposed so as to sandwich the polarized electrodes, and a gasket disposed between the pair of collectors so as to surround the pair of polarized electrodes. The electrode plate body is attached to each of the collectors located at the outermost side in a laminated direction of the layered cell. A sealing material having a higher gas barrier property than the collectors is disposed so as to seal an interface between the collectors and the electrode plate in the outer package.

摘要： The invention provides a multilayer secondary battery in which a positive electrode having a positive electrode active substance layer formed on a flat sheet-form collector and a negative electrode having a negative electrode active substance layer formed on a flat sheet-form collector are stacked together in opposite relation via a separator. The positive electrode active substance layer differs in area from the negative electrode active substance layer. Active substance-free portions with no active substance layer coated on them are formed on at least adjoining two sides of the outer periphery of a collector of a smaller area electrode having a smaller active substance layer area. The surface of the collectors at the active substance-free portions is covered with an insulating substance layer. The end face of the insulating substance layer that faces away from a side contiguous to an active substance layer and the end face of a larger area electrode having a larger active substance layer area are located and stacked together on the same plane that intersects vertically an electrode plane.

摘要： Tantalum powder and solid electrolytic capacitor using the same are disclosed. Cohered powder or Low CV powder is added to High CV powder in order to noticeably enhance an anchor effect during molding and therefore to increase the mechanical strength of a molding. Further, the addition of powder cohered beforehand prevents a contraction ratio from increasing at the time of sintering and thereby prevents the cavity distribution of an anode body from increasing, so that the electrical characteristic is improved.
