A cell is provided. The cell includes a cell element including a positive electrode, a negative electrode, an electrolyte and a laminate film including an exterior layer, a metal layer, an interior layer, and a welded layer formed of the interior layer; wherein a thickness of the welded layer is larger than 5 m in a flat portion of the interior layer, wherein the welded layer increases in thickness from the flat portion to an end portion of the welded layer, and wherein when a thickness of the laminate film is t, a thickness of the interior layer is p and a thickness of the laminate film in the welded layer is t1, a following equation is satisfied: t2p2+5<t1<t25 (m).

Provided is a joint treatment method that enables smooth joint treatment without damaging the ultraviolet radiation curable resin formed on the interior sheet surface. The joint treatment method is for joining a butt joint portion of interior sheets, the protective layer being formed as a surface layer of each of the interior sheets. The method includes: (1) a step of injecting a joint treatment agent, which has no dissolving ability with respect to at least the protective layer, into the butt joint portion; and (2) a step of attaching, before the injected joint treatment agent is cured, an adhesive tape so as to straddle the butt joint portion such that the tape is in contact with the protective layer and the joint treatment agent present in the butt joint portion.

A method for forming a hybrid structure is provided. The method includes applying a sealant to a first component fabricated from a first material, coupling an isolation sheet to the sealant, and coupling a second component to the isolation sheet. The isolation sheet and the second component are fabricated from a second material that is different than the first material to facilitate preventing formation of a galvanic cell within the hybrid structure.

A method of forming an injection-bonded joint includes providing a first part and a second part having a second part upper edge and a second part lower edge, and forming a chamber wall within a bondline region between mating surfaces of the first part and the second part. The chamber wall divides a bondline length of the bondline region and defines at least one adhesive chamber. The method further includes forming a bondline dam along each of the second part upper edge and the second part lower edge in a manner such that the chamber wall, the bondline dams, and the mating surfaces collectively enclose the adhesive chamber having a chamber upper edge and a chamber lower edge. The method also includes injecting a structural adhesive into the adhesive chamber through an injection port and discharging excess adhesive from the adhesive chamber through a bleed hole.

A cell is provided. The cell includes a cell element including a positive electrode, a negative electrode, an electrolyte and a laminate film including an exterior layer, a metal layer, an interior layer, and a welded layer formed of the interior layer; wherein a thickness of the welded layer is larger than 5 m in a flat portion of the interior layer, wherein the welded layer increases in thickness from the flat portion to an end portion of the welded layer, and wherein when a thickness of the laminate film is t, a thickness of the interior layer is p and a thickness of the laminate film in the welded layer is t1, a following equation is satisfied: t2p2+5<t1<t25 (m).

The invention relates to a device for setting a setting element having a first plastic material in a component having a second plastic material, comprising a rotational advancing unit, by means of which the setting element can be rotated about an axis of rotation and simultaneously an axial force acting in the direction of the axis of rotation can be applied to the setting element in order to drive the setting element into the component, a friction welding joint thereby being produced between the setting element and the component, a differential-distance measuring apparatus for measuring the differential distance between a surface of the component and a surface of the driven setting element, and a control unit for controlling the rotational advancing unit in dependence on the measured differential distance.

A method of forming an injection-bonded joint may include forming a chamber wall within a bondline region between mating surfaces of a first part and a second part. The chamber wall may divide a bondline length and define at least one adhesive chamber. The method may include injecting a structural adhesive into the adhesive chamber through an injection port, and discharging excess adhesive from the adhesive chamber through a bleed hole.
