`
`AMENDMENTS TO THE CLAIMS
`
`This listing of claims replacesall prior versions of claims in the application.
`
`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;
`
`a pair of end plates provided on both sides in a first direction of the battery laminate, the
`
`first direction being a direction in which the secondary batteries and the spacers are arranged; and
`
`a pressurizing unit for pressurizing the battery laminate,
`
`the pressurizing unit being
`
`provided between oneof the pair of end plates and the battery laminate, wherein
`
`each of the secondary batteries comprises:
`
`an electrode assembly; and
`
`an exterior body that houses the electrode assembly, and has a protrusion whtehswels
`
`imwardte-—press applying pressure to the electrode assembly in the first direction, and whieh
`
`deferms configured to deform with expansion of the electrode assembly in_a second direction
`
`opposite to the first direction,
`
`the protrusion being inward of upper _and lower portions of the exterior body and
`
`configured to expand outward of the upper and lower portions of the exterior body with said
`
`expansion.
`
`2.
`
`(Original) The power storage device according to claim 1, wherein
`
`the pressurizing unit pressurizes the battery laminate at constant pressure, when thickness
`
`change in thefirst direction of the secondary batteries is less than 5%.
`
`
`
`Application No.: 16/718,910
`
`Docket No.: P191327US00
`
`3.
`
`(Original) The power storage device according to claim 1, wherein
`
`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
`
`a conductive memberfor a power source for connecting a powersourceto at least one of a
`
`plurality of the secondary batteries, wherein
`
`the conductive member for a power source has a movable part with respect to the first
`
`direction.
`
`6.
`
`(Previously Presented) The powerstorage device according to claim 1, further comprising
`
`a pressure sensorthat detects pressure acting on the secondary batteries in thefirst direction,
`
`wherein
`
`at least one of a first control of adjusting pressure applied by the pressurizing unit and a
`
`second control of outputting information for changing a charging and discharging condition of the
`
`secondary batteries is performed on the basis of detection information of the pressure sensor.
`
`7.
`
`(Previously Presented) The powerstorage device according to claim 1, further comprising
`
`
`
`Application No.: 16/718,910
`
`Docket No.: P191327US00
`
`a displacement sensor that detects thickness changein the first direction of the secondary
`
`batteries, wherein
`
`at least one of a first control of adjusting pressure applied by the pressurizing unit and a
`
`second control of outputting information for changing a charging and discharging condition of the
`
`secondary batteries is performed on the basis of detection information of the displacement sensor.
`
`8. (Previously Presented) The powerstorage device according to claim 1, further comprising
`
`a gap located between the electrode assembly and a bottom portion of the exterior body.
`
`9. (New) A powerstorage device comprising:
`
`a battery laminate formed by alternately arraying a plurality of secondary batteries and a
`
`plurality of spacers;
`
`a pair of end plates provided on both sides in a first direction of the battery laminate, the
`
`first direction being a direction in which the secondary batteries and the spacers are arranged; and
`
`a pressurizing unit for pressurizing the battery laminate,
`
`the pressurizing unit being
`
`provided between oneof the pair of end plates and the battery laminate, wherein
`
`each of the secondary batteries comprises:
`
`an electrode assembly; and
`
`an exterior body that houses the electrode assembly, and has a protrusion which swells
`
`inward to press the electrode assembly in the first direction, and which deforms with expansion of
`
`the electrode assembly,
`
`wherein the pressurizing unit is at least one selected from a spring and a linear motion
`
`device.
