Abstract
Apparatus and methods are provided for energy storage devices capable of mitigating the pressure differentials between adjacent bi-polar units using a pressure equalization valve at a projection from a substrate of a bi-polar unit, which prevents the pressure equalization valve from being submerged by free liquid in the unit.
Claims21
A system for mitigating pressure differentials between cells in an energy storage device, the system comprising:
- a substrate;
- a projection extending from the substrate;
- and
- a pressure equalization valve, located at the projection, a threshold distance from the substrate.
1 more element
A method for mitigating pressure differentials between cells in an energy storage device, the method comprising:
- allowing gas to transfer between adjacent cells through a pressure equalization valve located at a projection located at a substrate;
- and
- preventing a liquid level from submerging the pressure equalization valve located a threshold distance from the substrate.
