Abstract
A prismatic battery according to one embodiment of the present invention includes a flat electrode groupstacked or rolled by mutually positive and negative electrodes with a separator therebetween, a pressing plateA, a current collecting bodyA orB and a plurality of exposed sections, at least one end of the positive and negative electrodes substrates in a width direction being uncoated with a positive or negative electrode mixture. The pressing plateA is welded to the exposed sections. The pressing plateA includes opposing surfaces with a space therebetween provided by folding back a metal plate, and includes a slitalong a folded back section at least to one of the opposing surface's side. The exposed sectionsare inserted into a gap of the pressing plateA, and the exposed sectionsand the pressing plateA are welded by a high energy beam from a transverse direction through the slit. This provides a prismatic battery for large current application in electric vehicles and hybrid electric vehicles.
