An energy storage system includes: multiple cells, each cell having a first end with anode and cathode terminals, and a second end opposite the first end, the cells arranged so that the second ends are aligned; for each of the cells, electrical connections coupled to the anode and cathode terminals at the first end; and a heat pipe having a flat evaporation surface facing the second ends.

Energy storage system with heat pipe thermal management

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.
