Abstract: Provided herein are electrochemical cells having improved heat collection and transfer systems. For example, one electrochemical cell includes a drawn can having a blind side and a second side opposite the blind side. The cell also includes a positive terminal disposed in the blind side of the can and electrically coupled to at least one positive electrode disposed within the can and a negative terminal disposed in the blind side of the can and electrically coupled to at least one negative electrode disposed within the can. The cell further includes a base coupled to a substantially flat edge disposed on the second side of the can. A bottom surface of the base is adapted to maintain a substantially flat configuration when coupled to a heat sink.
