Abstract
Official abstract text for this publication.
In a prismatic secondary battery, an internal negative electrode terminal is electrically connected to a collector through through-holes formed in a sealing plate, a gasket, and an insulating member in a manner electrically insulated from the sealing plate. The sealing plate has one face on which a protrusion is formed, an insulating plate has a face that is on the sealing plate and on which a concave portion fitted to the protrusion is formed, each of the protrusion and the concave portion of the insulating plate is provided at one position on respective sides of the through-hole, and at least one of the protrusions has a top face on which a concave portion is formed. The battery having such a structure is unlikely to cause rotary displacement between the insulating plate and the sealing plate even when a rotary torque is applied to the internal terminal.
First claim
Opening claim text (preview).
What is claimed is: 1. A prismatic secondary battery comprising: a prismatic hollow outer body having a mouth portion and a bottom; a sealing plate sealing up the mouth portion; an electrode assembly being stored in the prismatic hollow outer body; and an internal terminal being electrically connected to the electrode assembly, a first insulating member being disposed on a first face of the sealing plate, a second insulating member being disposed on a second face of the…
