Steel prismatic battery with anisotropic thermal conductivity materials

A cell for a prismatic battery assembly, the cell comprising:

• an enclosure including:
• a first end,
• a second end, wherein a heat dissipating element extends along the second end,
• a side wall extending between the first end and the second end, wherein a layer of anisotropic material extends in a direction parallel to the side wall, the anisotropic material having 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 greater than the second level of thermal conductivity, and
• a terminal disposed at the first end;
• and
• wherein, during operation of the prismatic battery assembly, 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.
