Nested heatsink housing for lithium ion cells

A method of manufacturing a cell comprising the steps of:

• a) disposing an electrical cell between a first half section of a cell housing and a second half section of the cell housing, the second half section being identical to the first half section, the first half section comprising:
• a longitudinal side having a first end and a second end;
• a first lateral side extending perpendicularly to the longitudinal side from the first end, the first lateral side having a first tongue, the first tongue having a first tongue lip extending toward the longitudinal side;
• and
• a second lateral side extending perpendicularly to the longitudinal side from the second end, the second lateral side having a first groove, the first groove having a first groove lip extending toward the longitudinal side;
• b) engaging the first tongue of the first half section with the first groove of the second half section and the first tongue of the second half section with the first groove of the first half section;
• c) applying an even pressure along the longitudinal side of the first and second half sections;
• and
• d) securing the first and second half sections to each other.

A cell housing comprising:

• a first half section comprising:
• a longitudinal wall having a first end and a second end;
• a first lateral wall extending perpendicular to the first longitudinal wall from the first end, the first lateral wall having a tongue at a free end thereof;
• and
• a second lateral wall extending parallel to the first lateral wall from the second end, the second lateral wall having a groove at a free end thereof;
• a second half section, identical to the first half section, wherein a tongue of the second half section is inserted into the groove of the first half section and the tongue of the first half section is inserted into a groove of the second half section;
• a first clip securing the first half section to the second half section at the free end of the first lateral wall;
• and
• a second clip securing the first half section to the second half section at the free end of the second lateral wall.
