Abstract: A battery capable of obtaining a high capacity and reducing its expansion is provided. A spirally wound electrode body formed through laminating a cathode and an anode with a separator and an electrolyte in between to form a laminate and spirally winding the laminate is included in a package member made of an aluminum laminate film. An anode active material layer includes an agglomerated graphite material in which a plurality of primary particles made of graphite having fine pores are agglomerated so that the orientation planes thereof are not parallel to each other, at least in part, to form secondary particles. In the agglomerated graphite material, the total volume of fine pores with a diameter from 10 nm to 1×105 nm inclusive estimated by mercury porosimetry ranges from 0.5 cm3/g to 1.5 cm3/g inclusive per unit weight.

Abstract: The invention provides a composition for electolyte and a high molecular weight electrolyte capable of inhibiting lowering a capacity when a battery is stored in a state of charge, and a battery. The high molecular weight electrolyte contains an electrolytic solution and a high molecular weight compound. The electrolytic solution includes a compound having P—O—Si bond or B—O—Si bond. Thereby, an unreacted polymerizable compound can be inhibited from reacting in the electrode, increase in resistance can be inhibited, and lowering a capacity can be inhibited.

Abstract: A cold cathode electronic device capable of removing pollution of emitter electrodes occurring during manufacturing of the device, to thereby enhance emission characteristics of the emitter electrodes and luminous efficiency of a phosphor layer. The cold cathode electronic device includes hydrogen occlusion metal incorporated in a gate electrode and/or an anode electrode. A field emission luminous device and a cold cathode luminous device each including such a cold cathode electronic device are disclosed.

Abstract: A method for manufacturing a display device is available that is capable of remarkably improving life characteristics of a display device. A display device placed in a chamber is evacuated to about 10.sup.-7 Torr. Then, reducing gas is introduced into the display device and held therein for several minutes, followed by evacuation of the display device to about 10.sup.-5 Torr. The reducing gas introducing and discharge steps are repeated several times. Thereafter, evacuation of the display device is carried out while keeping the chamber at about 300.degree. C., followed by sealing of the display device.

Abstract: An elastomer is molded by a reaction injection molding of polyurethane resins, polyurea resins, polyurethane/urea resins and polyurea/amide resins in the presence of an internal release agent which is a polyester condensate of a saturated or unsaturated fatty acid having a hydroxy group produced by transesterification or a molecular end-aminated or iminated polyester condensate. The elastomer has a good releasing property and a good coating property.
