Patent ID: 7022432

Claim:
A prismatic sealed battery module comprising: electrode plate groups each constituted by alternately layering positive and negative electrode plates with a separator interposed therebetween; an electrolyte; a prismatic battery case for accommodating the electrode plate groups and the electrolyte; the positive or negative electrode plates protruding from an end face of at least one of the electrode plate groups being bonded to a first collector member, an external terminal connected to a central part of the first collector member facing an inner surface of a side end wall of the battery case, said electrode plate groups having side edges; a second collector member directly contacting and connecting the side edges of adjacent ones of the electrode plate groups, said second collector member being located between said side edges to serve as both a collector member and a partition wall between said adjacent electrode plate groups and provide a current path limited to a space between said side edges of said adjacent electrode plate groups.
