Abstract: A device and method of generating an electrical potential including an electrochemical cell, and at least one heat source, cooling source or both. The electrochemical cell includes an anode and a cathode connected by a polymer electrolyte layer, preferably a dry polymer electrolyte layer. The heat source, if present, is placed in direct thermal contact with one of the anode or cathode, while the cooling source, if present, is placed in direct thermal contact with one of the anode or cathode not in contact with the heat source. The resulting temperature differential between the anode and cathode induces a concentration gradient between the anode and the cathode generating the electrical potential.

Abstract: Redox reactions that occur at the electrodes of batteries require transport of both ions and electrons to the active centers. Reported is the synthesis of a block copolymer that exhibits simultaneous electronic and ionic conduction. A combination of Grignard metathesis polymerization and click reaction was used successively to synthesize the block copolymer containing regioregular poly(3-hexylthiophene) (P3HT) and poly(ethylene oxide) (PEO) segments. The P3HT-PEO/LiTFSI mixture was then used to make a lithium battery cathode with LiFePO4 as the only other component. All-solid lithium batteries of the cathode described above, a solid electrolyte and a lithium foil as the anode showed capacities within experimental error of the theoretical capacity of the battery. The ability of P3HT-PEO to serve all of the transport and binding functions required in a lithium battery electrode is thus demonstrated.
