1. An energy storage module comprising:
at least two energy storage devices,
wherein the at least two energy storage devices are connected in series,
wherein each of the at least two energy storage devices includes:
an electrode assembly including electrodes and separators, wherein the electrodes and the separators are alternately stacked in a vertical direction of the electrode assembly;
an external member accommodating the electrode assembly therein;
electrode leads joined to the electrodes provided in the electrode assembly;
a first terminal portion provided to be in contact with an upper surface or a lower surface of one of the at least two energy storage devices; and
a second terminal portion provided to be in contact with an upper surface or a lower surface of the other of the at least two energy storage devices,
wherein each of the first and second terminal portions includes:
a conductive region having an electrically conductive surface and provided to face the electrode leads provided in the one and the other of the at least two energy storage devices; and
an insulating region provided at one side of the conductive region and having an electrically insulating surface, and
wherein the at least two energy storage devices are stacked in the vertical direction so that the electrode leads of the at least two energy storage devices are electrically connected to each other,
wherein an area of an upper surface of the insulating region is smaller than an area of the upper surface of each energy storage device,
wherein the conductive region and the insulating region overlaps with the electrode assembly in the vertical direction,
wherein the insulating region includes:
a connection section extending from the conductive region; and
a bent section extending from the connection section, bent from the connection section in the vertical direction, and provided to surround each of the one and the other of the at least two energy storage devices, and
wherein the energy storage module further comprising a cooling member disposed at one side of each of the at least two energy storage devices and provided to be in contact with the bent section.
