Abstract
The connection structure between unit cells connects a plurality of batteries B1 and B2 in series with bottomed cylindrical battery cases 2 and 5 which function as electrode terminals on one side, sealing plates 3 which close the opening portions of the battery cases 2 and 5 which function as electrode terminals on another side, and the first ring 1a with a flange is conductively connected at a bottom portion of a battery case 2 of one battery B1, the second ring 1b with a flange is conductively connected at an upper portion of the sealing plate 3 of another battery B2, and the first ring 1a and the second ring 1b are fitted.
Claims16
A connection structure between unit cells connecting a plurality of batteries in series, the batteries having bottomed cylindrical battery cases, which function as electrode terminals on one side, and sealing plates, which close the opening portions of the battery cases and which function as electrode terminals on another side,
- wherein a first ring having a flange is jointed at a bottom portion of the battery case of one battery in a conductive manner and a second ring having a flange is jointed at an upper portion of the sealing plate of an adjacent battery in a conductive manner,
- wherein said first ring and said second ring are fitted together, and
- wherein a ventilating groove or a ventilating pore, which ventilates to atmospheric air, is provided on a jointed surface of at least one flange of said first ring and said second ring.
