Abstract
A battery including a battery case, an electrode assembly in the battery case, the electrode assembly including a plurality of windings that are wound about a winding axis, the winding axis being oriented parallel to a bottom surface of the battery case, and a deformable member between the electrode assembly and the bottom surface of the battery case, the deformable member being pressed between the electrode assembly and the bottom surface of the battery case.
Claims18
A battery, comprising:
- a battery case, the battery case including a bottom surface inside the battery case;
- an electrode assembly in the battery case, the electrode assembly including a first plurality of windings that are wound about a first winding axis, the winding axis being oriented parallel to the bottom surface of the battery case;
- and
- a deformable member inside the battery case between the electrode assembly and the bottom surface of the battery case, the deformable member extending along the bottom of the case in a direction parallel to the first winding axis, and the deformable member directly contacting the electrode assembly and being pressed between the electrode assembly and the bottom surface of the battery case.
