Abstract
A battery cell design is disclosed that provides a predictable pathway through a portion of the cell (e.g., the cell cap assembly) for the efficient release of the thermal energy that occurs during thermal runaway, thereby reducing the chances of a rupture in an undesirable location. Furthermore the disclosed design maintains the functionality of the cell cap as the positive terminal of the cell, thereby having minimal impact on the manufacturability of the cell as well as its use in a variety of applications.
