Kind Code:
A1
Abstract:
An electrical storage module comprising a plurality of electrical storage devices and a first current collector holding the plurality of electrical storage devices. The electrical storage devices each include: a case having an opening; an electrode assembly housed in the case and comprising a first electrode and a second electrode; and a seal assembly sealing the opening. The case includes a tube portion having an opening in one end thereof, and a bottom portion closing the other end of the tube portion. The case is electrically connected to the first electrode. The first current collector has a plurality of first through-holes respectively housing and positioning the plurality of electrical storage devices, the first through-holes having peripheral portions being electrically connected to the case. In this way, it is possible to increase the energy density of the electrical storage module.
