ELECTRICITY STORAGE MODULE
First Claim
1. An electricity storage module comprising:
- a layered object in which a plurality of power storage elements each having positive and negative foil-shaped lead terminals that project in an outward direction from an end portion are layered such that the lead terminals are arranged in pairs of equal polarity, the pairs of lead terminals being arranged with alternating polarities;
connection members that each connect the lead terminals of adjacent power storage elements to each other, and each have a shape in which a first connection portion and a second connection portion that are provided parallel with each other are coupled by coupling portions at respective end portions; and
an insulating holding member that is arranged between the layered object and the connection members, has connection member holding portions that hold the connection members on a surface on a side opposite to a surface that opposes the layered object, and has slits provided so as to extend along edge portions of the connection members held by the connection member holding portions,wherein the lead terminals are connected to the connection members by being inserted through the slits and folded over onto the connection members, andadjacent lead terminals having the same polarity are connected in parallel by the first connection portions and the second connection portions, and lead terminals that have different polarities and are connected in parallel in a first connection portion and a second connection portion are connected in series by the coupling portions.

Abstract
An electricity storage module includes a layered object obtained by layering power storage elements each having positive and negative foil-shaped lead terminals that project in an outward direction from an end portion, and connection members that connect the lead terminals of adjacent power storage elements to each other. An insulating holding member is arranged between the layered object and the connection members. Connection member holding portions that hold the connection members on the surface on the side opposite to the surface that opposes the layered object are provided on the insulating holding member, and slits are provided on the insulating holding member so as to extend along edge portions of the connection members held by the connection member holding portions. The lead terminals are connected to the connection members by being inserted through the slits and folded over onto the connection members.
