A laminated cell () of the present invention includes a laminated body () formed by sequential stacking a negative electrode (), a separator (), a positive electrode (), and a separator (). At least one of surfaces of the positive electrode () or the negative electrode () in a stacking direction (S) has a portion to which a resin member () is bonded. The separators each have a portion bonded to the resin member () on a side facing the at least one of surfaces. In the present invention, since the separators and at least one of the positive electrode and the negative electrode are integrated together, misalignment in a stacking work can be easily suppressed and the laminated cell has excellent productivity.

Laminated cell and method for manufacturing same

A part has separator layers of resin laminated on each other with heat-resistant layers interposed among them and a sheath (laminated sheet) laid on each side of the laminated separator layers. The part is held, pressurized, and vibrated by a pressure vibrator and a jig receiver. The pressure vibrator and jig receiver are provided with projections that pressurize, vibrate, and break the heat-resistant layers, thereby melting and welding together the resin of the separator layers at the broken part.

Secondary battery manufacturing method, secondary battery, welding apparatus thereof

A bumper absorber () has a squared U-shaped cross section formed of: a vertical face () extending in a top-bottom direction and a vehicle width direction, and a top face () and a bottom face () respectively extending rearward from a top end and a bottom end of the vertical face (). The bumper absorber () is configured such that the top face () and the bottom face () thereof are supported by the bumper reinforcement () via multiple attachment members (to), and an interval between the attachment members adjacent to each other in the vehicle width direction is set to decrease from end portions () in the vehicle width direction toward a central portion () in the vehicle width direction.
