Tesla patents battery cell with top-mounted pressure vent

Tesla describes a design for an individual battery cell where the electrical connections and a safety vent are located on the top surface. The vent is built to release pressure in the opposite direction of the cell's bottom, while the electrical contacts are flat surfaces.

Why it mattersThis filing details a specific structural arrangement for battery safety and connection, which is a routine engineering improvement for managing heat and pressure in energy storage systems.

In the filing’s own words

A system for incorporating one or more individual energy cells is provided. Individual energy cells include a top surface having a center terminal and an outer terminal. The top surface may include a pressure venting element configured for venting in an opposite direction of a bottom surface. The first terminal and the second terminal may be substantially planar electrical contacts.

What exactly they claim (claim 1)

1. An energy storage device, comprising: a first terminal; a second terminal; a pressure venting element; a housing comprising a housing surface, wherein the housing surface comprises the first terminal, the second terminal and the pressure venting element; and an energy storage material disposed within the housing.
