Abstract
Various arrangements of pressurized battery modules are detailed herein. Such a pressurized battery module may include a sealed battery module housing. The pressurized battery module may include multiple pouch cells. Each pouch cell may be located within the sealed battery module housing. The pressurized battery module may further include an insulative oil that is pressurized within the sealed housing. This insulative oil may exert pressure on an external surface of each pouch cell within the pressurized battery module.
