STEEL PRISMATIC BATTERY WITH ANISOTROPIC THERMAL CONDUCTIVITY MATERIALS

A prismatic battery assembly includes a cell, a heat dissipating element, and a layer of anisotropic material. The cell includes an enclosure having a first end, a second end, a side wall extending between the first end and the second end, and a terminal disposed at the first end. The heat dissipating element extends along the second end. The layer of anisotropic material extends in a direction parallel to the side wall and has a first level of thermal conductivity in the direction parallel to the side wall and a second level of thermal conductivity in a direction transverse to the side wall. The first level of thermal conductivity is greater than the second level of thermal conductivity. Heat generated within the enclosure of the cell is dissipated along the layer of anisotropic material in the direction parallel to the side wall and into the heat dissipating element.
