Prismatic sealed battery module

摘要

A prismatic sealed battery module includes a prismatic battery case (3), an electrode plate group (8) constituted by alternately layering positive and negative electrode plates with a separator arranged therebetween, and an electrolyte. The positive or negative electrode plates protruding from respective end faces of the electrode plate group are bonded to a collector member (16). A metal connector (18) is fixed to the central part of the collector member facing the inner surface of the side end wall (3a) of the battery case. The collector member is connected, at the metal connector (18), to an external terminal (25) using an external connecting bolt (23).
