ABSTRACT:
A battery module includes at least one electrochemical cell. The electrochemical cell includes a first terminal conductively coupled to a first electrode and a body portion configured to function as a second terminal and conductively coupled to a second electrode via a pressure relief portion. The battery module further includes an end cap comprising a conductive portion and an insulating portion, the conductive portion being conductively coupled to the body portion. The pressure relief portion is configured to separate from the body portion to a deployed position when a pressure within the body portion reaches a first predetermined level, thereby substantially breaking the conductive coupling between the body portion and the second electrode. The insulating portion substantially prevents formation of a conductive coupling between the body portion and the second electrode when the pressure relief portion is in the deployed position.
