Abstract
A system includes a battery cell having an internal heat fin and a first electrically insulating layer disposed over at least a portion of a single side of the internal heat fin. The battery cell includes an electrochemical stack disposed above the first insulating layer and the internal heat fin in a stack. The battery cell also includes a pouch material film configured to hermetically seal with one side of the internal heat fin or the first insulating layer about the electrochemical stack such that the internal heat fin forms an outer boundary of the battery cell. The pouch material film includes a metallic foil layer disposed between a second electrically insulating layer and a third electrically insulating layer.
Claims19
A system, comprising:
- a battery cell, comprising:
- an internal heat fin;
- a first electrically insulating layer disposed over at least a portion of a single side of the internal heat fin;
- an electrochemical stack disposed above the first insulating layer and the internal heat fin in a stack;
- and
- a pouch material film configured to hermetically seal with one side of the internal heat fin or the first insulating layer about the electrochemical stack such that the internal heat fin forms an outer boundary of the battery cell, and wherein the pouch material film comprises a metallic foil layer disposed between a second electrically insulating layer and a third electrically insulating layer.
A battery cell, comprising:
- an internal heat fin;
- a first electrically insulating layer stacked on top of the internal heat fin;
- a lithium ion electrochemical cell stacked on top of the first electrically insulating layer;
- a second electrically insulating layer disposed over the lithium ion electrochemical cell;
- a metallic foil layer disposed over the second electrically insulating layer;
- and
- a third electrically insulating layer disposed over the metallic foil layer, wherein one or more of the first electrically insulating layer, the second electrically insulating layer, the metallic foil layer, and the third insulating layer are configured to hermetically seal the lithium ion electrochemical cell to the internal heat fin such that the internal heat fin is an outermost layer of the battery cell.
