1. A stacked battery comprising:
a first battery cell having:
a first cathode current collector comprising a first polymer and a first metal at least partially coating the first polymer, wherein the first cathode current collector is characterized by a first surface and a second surface opposite the first surface, and a first anode current collector comprising a second polymer and a second metal at least partially coating the second polymer, wherein the first anode current collector is characterized by a first surface and a second surface opposite the first surface; and
a second battery cell having:
a second cathode current collector comprising the first polymer and the first metal at least partially coating the first polymer, wherein the second cathode current collector is characterized by a first surface and a second surface opposite the first surface, and
a second anode current collector comprising the second polymer and the second metal at least partially coating the second polymer, wherein the second anode current collector is characterized by a first surface and a second surface opposite the first surface, and wherein the first anode current collector is coupled with the second cathode current collector along the first surface of the first anode current collector and the first surface of the second cathode current collector.
