ABSTRACT:
A sealed prismatic battery includes an electrode plate group having positive and negative electrode plates stacked upon one another with a separator interposed therebetween, collectors each connected to a lead portion on either side of the electrode plate group and having one or more connection bosses formed in a middle part thereof, and a battery case, generally rectangular in shape, for accommodating the electrode plate group connected with the collectors. The battery case has a through-hole for the connection boss of the collector to penetrate therethrough via a rubber seal. A battery module includes a plurality of the sealed prismatic batteries, the connection bosses of which are connected to each other.
