Abstract
Official abstract text for this publication.
An energy storage apparatus includes an energy storage device and a spacer, in which the spacer has a first member that abuts on a side surface of the energy storage device that faces a first direction, and a second member that is disposed on the first member in a second direction, the second direction intersecting the first direction, the second member supporting an end portion of the first member in the second direction, and the first member has higher heat resistance than the second member.
First claim
Opening claim text (preview).
1 . An energy storage apparatus comprising an energy storage device and a spacer, wherein the spacer includes: a first member that abuts on a side surface of the energy storage device that faces a first direction; and a second member that is disposed on the first member in a second direction, the second direction intersecting the first direction, the second member supporting an end portion of the first member in the second direction, and the first member has higher heat resistance than the second member. 2 . The energy storage apparatus according to claim 1 , wherein the first member has higher hardness than the second member. 3 . The energy storage apparatus according to claim 1 , wherein the second member has an opening at a central position, and the first member is disposed within the opening. 4 . The energy storage apparatus according to claim 1 , wherein the first member has a first concave portion at an end portion, and the second member has an engaging part that engages with the first concave portion in the first direction. 5 . The energy storage apparatus according to claim 1 , wherein the second member has a first concave portion at an end portion, and the first member has an engaging part that engages with the first concave portion in the first direction. 6 . The energy storage apparatus according to claim 1 , wherein the second member has a sandwiching part that sandwiches the first member. 7 . The energy storage apparatus according to claim 1 , wherein the second member has a second concave portion disposed lateral to the first member, or a through hole disposed lateral to the first member. 8 . The energy storage apparatus according to claim 1 , further comprising a joining member disposed between the energy storage device and the spacer, the joining member joining the energy storage device and the spacer, wherein the second member has a first surface on which the joining member is disposed, and the first member has a first protruding portion that protrudes from the first surface toward the energy storage device. 9 . The energy storage apparatus according to claim 8 , wherein the first protruding portion has a central protruding portion that is disposed so as to face a central portion of the energy storage device. 10 . The energy storage apparatus according to claim 8 , wherein the second member further has a second surface opposite to the first surface, and the first member further has a second protruding portion that is disposed on the opposite side of the first protruding portion and protrudes from the second surface.
