Abstract
Certain embodiments of the invention relate to the design of three-dimensional battery cells and their incorporation into battery modules and battery packs. The present invention may be particularly advantageous when incorporated into large battery packs, for example, those used in electric vehicles. The unique architecture of the battery cells of certain embodiments of the invention provides improved thermal performance with significant impact on cycle and calendar life when incorporated into a battery pack. Substantially higher pack energy density for a given cell energy density is provided when compared to a conventional cell. Battery cells can be strung together to form modules and packs with whatever series/parallel arrangement required for a particular application. Cooling, if needed, can be incorporated at the module level rather than the individual die level, as is the case with conventional architectures, dramatically reducing the cost of the system.
