摘要:
A packaged battery, an assembled battery, and a film-covered battery, which can prevent a dangerous state involving a high-pressure gas filled in the film-covered battery while ensuring a sealing reliability, are provided. The Packaged battery includes film-covered battery 1 including a battery element and exterior films forming a sealed space housing the battery element, and holding member 10 holding film-covered battery 1. The sealed space includes a housing section housing the battery element, and a pocket communicating with the housing section to expand when the pressure in the sealed space increases. The pocket includes a safety valve which activates when the pocket expands. Holding member 10 includes an opening and a cavity fitting the housing section therein. When the housing section is fitted into the cavity, at least part of the pocket and the safety valve protrude to the outside of the holding member from the opening.

A folding electric has an upper unit and lower unit. A hinge connects the upper unit to the lower unit. The hinge includes at least a perpendicular opening and closing shaft to open and close the upper unit with respect to the lower unit and a horizontal rotation shaft, fixed vertically to the surface of the lower unit, to rotate the upper unit with respect to the lower unit coming in contact with each other.

A fold-type cellular phone has a top unit, a bottom unit and a hinge coupling together the top unit and the bottom unit while allowing the top unit to turn and swivel with respect to the bottom unit. The top unit is first unfolded from a first folded position to an attitude angle of 160 to 170 degrees, and swiveled by 180 degrees to be folded onto the bottom unit in a second folded position at an attitude angle of 180 degrees. The swivel movement of the top unit causes a cam assembly to turn the top unit from the attitude angle of 160-170 degrees to an attitude angle of 180 degrees in the second folded position, thereby allowing the top unit to assume a suitable attitude with respect to the bottom unit.

A laminated battery has a battery element in which a plurality of positive electrode sheets, which are each composed of a positive electrode collector in which positive electrode material has been applied and in which a portion to which the positive electrode material has not been applied extends from one side, and a plurality of negative electrode sheets, which are each composed of a negative electrode collector in which a negative electrode material has been applied over an area that is greater than that of the positive electrode material and in which a portion to which the negative electrode material has not been applied extends from one side, are alternately stacked with interposed separators. On the side of the connection unit with a negative electrode lead, a portion of the negative electrode sheets that protrudes from the portions that have been applied with positive electrode material curves toward the connection unit. The spacing from the edges of the positive electrode sheets to the connection unit with the negative electrode lead on the side of the connection unit with the negative electrode lead is less than the spacing from the edges of the portions to which the positive electrode material has been applied to the connection unit with a positive electrode lead on the side of the connection unit with the positive electrode lead.

A film covered battery has a battery element equipped with a plurality of electrode plates laminated via separators, and an exterior film for hermetically sealing the battery element. A cover film is attached to a hollow present in predetermined regions set on a surface of the exterior film. The predetermined regions are regions obtained by removing overlap regions from projected regions obtained by projecting the electrode plates to the surface of the exterior film, the overlap regions being regions where the projected regions overlap with members interposed between the electrode plates at the outermost layers and the exterior film. It is possible to cover the hollow on the surface, without increasing the thickness of the film covered battery.

A battery element (2) includes a positive electrode and a negative electrode stacked via a separator. A collector portion (3) is formed by collectively bonding each of positive electrode plates and negative electrode plates which extend outward from this stacked region. Laminated films (5, 6) are obtained by laminating a thermally-fusible resin layer and a metal layer, and by sealing the battery element (2) and electrolyte by thermally fusing sealing portion (8) at a peripheral edge. A tab (4) is connected to collector portion (3) and extends outward from the laminated films (5, 6). An overlaying member (7) includes a protective region (7d) which protects the laminated films (5, 6) from corners (2c) of the battery element (2), corners (3c) of the collector portion (3) and corners (4c) of the tab (4), and a communication portion (7c) through which electrolyte can pass.

摘要:
Battery element 2 is sandwiched between and surrounded by casing films 4, 5 each having a thermo-fusing resin layer, and is sealed by thermally fused region 6 formed by thermally fusing around the overall periphery. Cross-link structure portion 13 is formed in part of thermally fused region 6 by cross-linking casing film 5, and gas release chamber 12 is formed with its leading end positioned in cross-link structure portion 13. Gas release chamber 12 is a portion which is surrounded by thermally fused region 6 along its periphery, and in which casing films 4, 5 are not thermally fused. Tube 14 which is open at both ends is connected to gas release chamber 12, while sandwiched between casing films 4, 5, with its leading end positioned in gas release chamber 12.
