摘要:
On the opposite end walls (8) of a flat, primatic battery case (2) of a battery module (1) where electrode terminals (12) are attached, protruding components (26) are formed such as to protrude further than the electrode terminals. Terminal holes (10) are formed in the end walls in which the electrode terminals are fitted, and the thickness of the end walls of the integral battery case in the vicinity of the terminal holes is not the same on both sides of each of the terminal holes. Also, each of the electrode terminals has a mounting structure comprising a disk-shaped seat (12a) from one surface of which the electrode terminal protrudes, a connecting protrusion (24) protruding from an opposite surface of the electrode terminal, an annular groove (40a) formed around and coaxial with said connecting protrusion, and an annular protrusion (40) around and coaxial with said annular groove. The engagement tabs (38) are formed extending radially and centred around the connecting protrusion. The engagement grooves (37) and the circular recess are connected and coplanar. The engagement tabs (38) and the annular protrusion (40) are connected and coplanar.

In a sealed rechargeable battery module wherein a safety vent device (13) is provided to release the internal pressure of the battery when the pressure has reached a predetermined value, the safety vent device comprises a valve case (25) formed with a vent (26) and a sealing protrusion (27) surrounding this vent, a valve body (31) inserted in the valve case including a sealing portion (28) that is brought in tight contact with the sealing protrusion, a rigid holder (29) for supporting the sealing portion, and a resilient portion (30) for pressing the rigid holder toward the vent, and a valve cover (32) formed with apertures (33) for closing the upper open end of the valve case in a state wherein the resilient portion of the valve body is compressed.
摘要:
A rectangular electrode plate (1) including a core metal sheet and a mixture paste coated thereon has a lead (2) on one long side edge thereof where no mixture is coated, and a mixture non-coated part (4) on the other side edge thereof. Positioning holes (5a, 5b) are punched only in the lead so that the stress exerted when punching the holes will not cause the mixture paste to fall off. Stacked electrode plates are accommodated within a magazine (22A) with a certain clearance (28) between the three side edges of the electrodes other than the lead and the inner surface of the magazine, and fed one by one to be assembled into an electrode plate group to form a battery.
