Abstract
The disclosure herein pertains to a pressure regulation system for use in a silicon dominate anode lithium-ion cell. The pressure regulation system regulates a lifetime pressure on the lithium-ion cell in order to correct for capacity loss and mechanical failure due the expansion of silicon during operation. The pressure regulation system along with a housing maintains a certain pressure range on the lithium-ion cells during the cycling and the operational life of the energy storage device.
