ABSTRACT:
Storage of electrical energy in an oxidation-reduction polymer material is optimized when the material is lignin and/or hydrazine is added to the material so as to facilitate bonding of the material to graphite. A preferred embodiment of the invention includes a storage device having an electron acceptor component separated from an electron donor component by a barrier which is impregnated with an electrolyte so as to electrically separate the two components while serving as an ion conduit. At least one of the layers includes an oxidation-reduction polymer material which either is lignin or is mixed with hydrazine, or both. The preferred energy storage material is a mixture of lignin, hydrazine and graphite, the latter being either added to the mixture or formed by graphitization upon heating of the lignin.
