WIPO Patent Application WO/2016/113798

Kind Code:

A1

Abstract:

This electrical storage module is provided with a battery block group comprising a plurality of battery cells, a connection terminal part joined to a terminal surface of each of the plurality of battery cells, and a heat conduction material disposed against each of the connection terminal parts. The heat conduction material comprises either of at least a member among a plurality of dotting members and a member having openings. In a planar view looking from a normal direction to the surface whereon the heat conduction material is disposed, the disposition of the heat conduction material at the central portion of a region surrounded by the outermost peripheral edge of the battery block group is such that the density of the heat conduction material is greater than that in the peripheral portion surrounding the central portion.
