Abstract
The present invention relates to a unique polymeric battery system of electrochemical cells that are connected in series, and can be of nanometer size. The polymers possess conjugated bonds along their backbones and high levels of metals. The invention also concerns methods for the fabrication of the polymers and battery system as well as methods for the use of the polymers as a nanoscale solid-state battery.
