`
`Listing of Claims:
`
`1.
`
`(Currently Amended) A powerstorage device comprising:
`
`a battery laminate formed by alternately arraying a plurality of secondary batteries and a
`
`plurality of spacers;
`

`provided between oneof the pair of end plates and the battery laminate, wherein
`
`each of the secondary batteries comprises:
`
`an electrode assembly including at least_one positive electrode, at least_one negative
`
`electrode, and at least one separator interposed therebetween, wherein the at least_one positive
`
`electrode, the at least one negative electrode, and the at least one separator are stacked in thefirst
`
`direction; and
`
`
`
`an exterior body that housesthe electrode assembly,-and-has-a-pretrusten-apphyinepressure
`
`
`
`the exterior body including:
`
`a case main body including a tubular side wall portion extending in a vertical
`
`direction perpendicular to the first direction, and having a first opening and a second
`
`openingat a first end and a second end, respectively, in the vertical direction of the tubular
`
`side wall portion:

`
`Docket No.: P191327US00
`
`a bottom portion sealing the first opening of the tubular side wall; and
`
`a sealing plate sealing the second opening of the tubular side wall,
`
`wherein the tubular side wall portion includes a first side wall and a second side
`
`wall opposite each other in the first direction,
`
`the first side wall has a first protrusion that protrudes inward in one direction along
`
`the first direction, the second side wall has a second protrusion that protrudes inward in an
`
`other direction opposite the one direction along thefirst direction,
`
`the first and second protrusions together hold the electrode assembly therebetween

`
`wherein a gap is located between the electrode assembly and the bottom portion of the
`
`exterior body in the vertical direction.
`
`2.
`
`(Original) The power storage device according to claim 1, wherein
`
`the pressurizing unit pressurizes the battery laminate at constant pressure, when thickness
`
`changein thefirst direction of the secondary batteries is less than 5%.
`
`3.
`
`(Original) The power storage device according to claim 1, wherein
`
`
`
`Application No.: 16/718,910
`
`Docket No.: P191327US00
`
`the pressurizing unit is at least one selected from a spring, a linear motion device, and a
`
`rubber member.
`
`4.
`
`(Original) The power storage device according to claim 1, further comprising
`
`a conductive memberthat connects electrode terminals of the secondary batteries adjacent
`
`to each other, wherein
`
`the conductive memberhasan extension part that extends and contracts in the first direction.
`
`5.
`
`(Previously Presented) The powerstorage device according to claim 1, further comprising
`
