BATTERY ENCLOSURES WITH STRUCTURAL ENHANCEMENTS

Abstract:

Batteries according to embodiments of the present technology may include an electrode stack including a separator positioned between an anode and a cathode. The batteries may include an electrolyte. The batteries may include an enclosure extending about the electrode stack and containing the electrolyte. The enclosure may include a rigid housing defining a volume in which the electrode stack and the electrolyte are contained. The rigid housing may define a flange extending about the rigid housing. The enclosure may include a lid extending across the rigid housing. The lid may be characterized by a length and a width, and the lid may define a protrusion extending beyond the length or width on a side of the lid at a location corresponding to a predetermined strain location.
