1. A system for a high-performance prismatic lithium-ion battery cell, the system comprising:
a battery cell stack including:
an electrode sub-assembly including a plurality of pairs of anode electrodes and cathode electrodes and including a planar side;
a polymeric shell disposed around the electrode sub-assembly and configured for providing mechanical protection and electrical insulation to the electrode sub-assembly; and
a metal foil sheet attached to the polymeric shell and disposed next to and in contact with the planar side of the electrode sub-assembly, wherein the metal foil sheet is configured for exchanging heat with the electrode sub-assembly.
