Method and apparatus for cooling and positioning prismatic battery cells

A method for cooling and positioning prismatic battery cells, comprising:

• sealing active material of a primastic battery cell in a pouch;
• attaching a cooling fin made of thermally conductive material to said cell;
• and
• attaching a pair of terminal tabs that reach into said pouch to draw heat away from said cell, wherein said attaching a cooling fin further comprises:
• folding railings along length of said cell;
• creating bent tabs in said cooling fin to attach said cooling fin to an area of said cell bounded by said railings;
• and
• sliding said cooling fin between said railings to fit around said area.

An apparatus for cooling and positioning prismatic battery cells, comprising:

• a prismatic battery cell with active material in a sealed pouch with a flat surface area;
• a cooling fin made of thermally conductive material comprising:
• a flat area in direct contact with said cell, wherein said flat area covers said flat surface area of said cell;
• and
• a corrugated area, extending from said flat area, wherein said corrugated area is not in direct contact with said cell but in direct contact with a coolant agent.

A method for positioning and cooling prismatic battery cells, comprising:

• attaching a cooling fin, made of thermally conductive material, comprising of a flat area and a corrugated area, to a prismatic battery cell with active material sealed in a pouch with a flat surface area, wherein said attaching comprises:
• attaching said flat area of said cooling fin to said flat surface area of said cell, whereby said flat area of cooling fin comes in direct contact with said cell;
• and
• positioning said corrugated area not in direct contact with said cell but in direct contact with a cooling agent.
