Polymer-Nanocarbon Composites for Energy Storage Applications

Market Overview:

Stationary energy storage is currently a major limitation to the utilization of renewable energy generation, from wind and solar, and for consumer or residential systems.  Current materials are not suitable for large format energy storage due to either cost or safety concerns. This technology provides low-cost materials for stationary electrical energy storage by integrating polymers with carbon nanomaterials in a manner that exploits the high-energy capacity of non-conductive  redox active polymers. High charge capacity electrodes are made by incorporating redox polymers, such as lignin, either during electrode synthesis or through adsorption. The carbon nanomaterial provides the conductivity and surface area and the polymer enhances the energy storage capability.  Importantly, the polymeric materials are abundant, and even renewable, and the fabrication processes are extremely cost effective.  The composite material and its synthesis process allow for the use of low-cost, non-conductive, but high charge-capacity redox polymers in large format supercapacitors and batteries at a reduced cost compared to traditional lead-acid batteries.

· Stationary energy storage
