Abstract
A battery assembly includes: a plurality of battery cells arranged in a first direction; a separator disposed between the plurality of battery cells; a restraint member that restrains the plurality of battery cells and the separator along the first direction, wherein the separator includes a first member including a base portion and a plurality of protrusions each protruding from the base portion in the first direction, and a second member disposed between the plurality of protrusions, the second member having a higher heat insulation property than a heat insulation property of the first member, the second member being more likely to be deformed than the first member.
Claims15
A battery assembly comprising:
- a plurality of battery cells arranged in a first direction;
- a separator disposed between the plurality of battery cells;
- and
- a restraint member that restrains the plurality of battery cells and the separator along the first direction, wherein
- the separator includes
- a first member including a base portion and a plurality of protrusions each protruding from the base portion in the first direction, and
- a second member disposed between the plurality of protrusions, the second member having a higher heat insulation property than a heat insulation property of the first member, the second member being more likely to be deformed than the first member.
A method of manufacturing a battery assembly, the method comprising:
- preparing a plurality of battery cells and a separator;
- arranging the plurality of battery cells and the separator alternately in a first direction;
- and
- restraining the plurality of battery cells and the separator along the first direction, wherein
- the preparing of the separator includes
- preparing a first member including a base portion and a plurality of protrusions protruding from the base portion in the first direction, and
- providing a second member disposed between the plurality of protrusions, the second member having a higher heat insulation property than a heat insulation property of the first member, the second member being more likely to be deformed than the first member, and
- the preparing of the first member includes causing a protruding height of each of the plurality of protrusions to be larger than a thickness of the second member.
