The case main body includes a bottomed case main body which has a flat accommodation space and of which one surface is opened, and a sealing plate attached to that one surface of the case main body which is opened. The electrode body is a flat electrode body, is accommodated in the flat accommodation space of the case main body, and has a part to which the terminal is joined. The terminal includes a base end attached to the sealing plate, an intermediate part extending from the base end toward the part to which the terminal is joined, along a surface on one side of the battery outer case, and a tip end joined to the part to which the terminal is joined. The tip end of the terminal is joined to a surface on one side of the part to which the terminal is joined, and pushes the part to which the terminal is joined.

Battery and battery manufacturing method

A secondary battery includes: a wound electrode body in a flat form impregnated with an electrolytic solution; an outer case in a flat form including a lid and a main body, the outer case including a curved portion, the curved portion formed into a curved surface into which the bottom surface and a wall surface of the outer case are connected; and an electric insulating film including a gap through which the electrolytic solution passes, the gap formed at a corner at the bottom surface side of the electric insulating film, the corner with the gap in the electric insulating film being clamped between the curved portion of the inner surface of the outer case and a corner at the bottom surface side of the wound electrode body.

Secondary battery

Provided is a conductive foam roll having a high surface opening ratio that achieves both cleaning performance and low resistance. A conductive foam rollincludes a shaft bodyand a conductive foam layeraround the shaft body, wherein the conductive foam layerhas a surface opening ratio of 50% to 90%, and wherein the conductive foam layercontains an ionic conductive agent that contains salt of diallyl-type ammonium cations, and at least one selected from the group consisting of N,N-bis(trifluoromethanesulfonyl)imide anions, and N,N-bis(fluorosulfonyl)imide anions.

Conductive foam roll

In a manufacturing method of a sealed battery, a positive terminal is provided on one end portion of a lid and a negative terminal is provided on another end portion of the lid. An end surface on the positive terminal side of the lid is inserted into an opening, and made to contact an inside wall of the opening. Then, an end surface on the negative terminal side of the lid is inserted into the opening, and the battery can and the lid are welded together. Therefore, even if metal foreign bodies get into the battery can at the time of manufacture, they will get in on the negative terminal side, so a decrease in voltage of the sealed battery is able to be suppressed.
