Abstract
A separator for use in a unit cell of an energy device includes a perimeter wall and a step portion extending from the perimeter wall along an inner surface of the perimeter wall. A midpoint of a height of the perimeter wall is aligned with a midpoint of a height of the step portion. A planar membrane extends across an area defined by an innermost surface of the step portion. The planar membrane is aligned with the midpoint of the height of the step portion. The planar membrane includes perforations.
Claims20
A separator for use in a unit cell of an energy device, the separator comprising:
- a perimeter wall;
- a step portion extending from the perimeter wall along an inner surface of the perimeter wall, wherein a midpoint of a height of the perimeter wall is aligned with a midpoint of a height of the step portion;
- a planar membrane extending across an area defined by an innermost surface of the step portion, the planar membrane aligned with the midpoint of the height of the step portion;
- and
- perforations in the planar membrane.
A separator for use in a unit cell of an energy device, the separator comprising:
- a perimeter wall configured to form a seal around edges of layers forming the unit cell;
- a step portion extending from an inner surface of the perimeter wall, wherein a height of the perimeter wall is greater than a height of the step portion;
- a planar membrane extending across an area defined by the step portion, the planar membrane aligned with a midpoint of the height of the step portion, the planar membrane having a thickness less than the height of the step portion;
- and
- perforations in the planar membrane,
- wherein the separator is a unitary piece of electrically insulating but ionically conducting material.
