A manufacturing method includes the steps of: preparing a battery case having an opening; fabricating an assembly by inserting a wound electrode body and a lid which includes a terminal connected to the wound electrode body and which closes the opening into the battery case; sandwiching the battery case by a pressing jig in a state where the opening faces downward to close a gap between the battery case and the lid; disposing the assembly so that the terminal faces upward by inverting the assembly in a state where the battery case is sandwiched by the pressing jig; and welding the lid and the battery case to each other in a state where the terminal faces upward and the battery case is sandwiched by the pressing jig.

Manufacturing method of battery and battery manufacturing system

A battery includes an electrode body and an internal terminal attached to the electrode body. The electrode body includes positive electrode sheets, negative electrode sheets, and separators. The positive electrode sheets and the negative electrode sheets are alternately stacked in a stacking direction, with each separator interposed between associated adjacent ones of the positive electrode sheets and the negative electrode sheets. The positive electrode sheets and the negative electrode sheets each include a collector foil. At least either portions of the collector foils of the positive electrode sheets or the negative electrode sheets are protruded beyond the separators in one direction. The protruded portions of the collector foils are piled in a stack in the stacking direction. The internal terminal includes a connector connected to the stack of the protruded portions of the collector foils. The stack of the protruded portions is bent around a base end of the protruded portions of the collector foils.

Battery and battery manufacturing method

A battery includes a case, an internal terminal, an external terminal, and an insulator. The internal terminal includes an internal terminal base and a shaft. The internal terminal base is disposed inside the case, with the insulator interposed between the case and the internal terminal base. The external terminal includes an external terminal base and a boss. The external terminal base is disposed outside the case, with the insulator interposed between the external terminal base and the case. The boss extends from the external terminal base. The boss receives the shaft of the internal terminal therethrough. The boss is pressure-welded to the shaft of the internal terminal.

Provided is a method of welding laminated metal foils that can prevent blowholes and spatter from being formed. It is a method of welding laminated metal foils sandwiched between a pair of metal plates to the pair of metal plates. The method of welding laminated metal foils sandwiched between a pair of metal plates to the pair of metal plates includes locally pressing and crimping the laminated metal foils sandwiched between the pair of metal plates at a welding point in a laminating direction, and welding the crimped pair of metal plates and laminated metal foils at the welding point.

A positive-electrode belt-shaped sheet is cut while the positive-electrode belt-shaped sheet and a negative-electrode belt-shaped sheet are continuously sent, a cut positive-electrode sheet laminated on the uncut negative-electrode belt-shaped sheet via a separator layer is sent and clamped, the uncut negative-electrode belt-shaped sheet is cut at a cutting gap between the positive-electrode sheets laminated thereon, so as to form a sheet unit including the positive-electrode sheet and the negative-electrode sheet, a lamination shape of the sheet unit is measured so as to determine good or bad of the lamination shape, the sheet unit is classified based on a good/bad determination result, and the sheet units determined as good products is collectively laminated and pressed so as to obtain a laminated electrode body. Here, the positive-electrode belt-shaped sheet is cut while the positive-electrode belt-shaped sheet is clamped.

Manufacturing method of laminated electrode body

The invention provides a manufacturing method of a sealed battery that includes a power generating element, a housing member, a lid member, a collector terminal member, and a first insulating member. This manufacturing method includes compressing the first insulating member with a protruding portion of the lid member. The method includes measuring a position of the lid member and a compression load applied by the lid member, and stopping compressing when a slope of the change in the compression load with respect to the position of the lid member reaches a predetermined value.
