Claims20
A battery containment structure comprising:
- a first pliable pouch surrounding a battery active region;
- a second pliable pouch surrounding the first pliable pouch, and configured to contain the first pliable pouch and battery active region therein during operation;
- and
- a vent carried by the first pliable pouch configured to vent gas from the battery active region responsive to a pressure or temperature of the gas within the first pliable pouch surpassing a predetermined threshold.
A method of operating a battery system comprising:
- venting a gas created by a battery active region disposed within a first pliable pouch through a vent carried by the first pliable pouch into a second pliable pouch, configured to contain the first pliable pouch during operation, responsive to a pressure or temperature of the gas surpassing a first predetermined threshold.
A battery system comprising:
- a battery active region connected to a battery terminal;
- a first pliable pouch containing the battery active region;
- a second pliable pouch containing the first pliable pouch;
- and
- a vent carried by the first pliable pouch configured to vent gas from the battery active region responsive to a pressure or temperature of the gas surpassing a predetermined threshold.
