Claims13
An apparatus for pressing a battery cell, the apparatus comprising:
- a first pressing plate;
- and
- a second pressing plate spaced from the first pressing plate to receive a battery cell therebetween and to press the battery cell,
- wherein at least one of the first pressing plate or the second pressing plate is formed of a shape memory material to provide a pressing member,
- wherein the shape memory material comprises a shape memory polymer,
- wherein the pressing member is configured to store a shape in accordance with the battery cell at a temperature at which the battery cell is driven, and
- wherein deformation of the pressing member due to a volume expansion of the battery cell acts as a force for returning the shape of the pressing member to an original shape of the pressing member after the battery cell is driven, thereby pressing the battery cell.
