Graphene-Based Electric Double Layer Capacitor

Our long-term objective is to create a new class of electric double layer capacitors (EDLCs) having electrical performance like aluminum electrolytic capacitors but with smaller size and higher reliability. Restated, we intend to create a smaller and more reliability replacement component that can be broadly used in existing electrolytic capacitor applications. Further, this replacement capacitor will be thin and potentially flexible, characteristics that should help promote its exploitation in totally new applications. Development is based on electric double layer charge storage using electrodes comprised of graphene nanosheet materials and a solid-state electrolyte. This new class of EDLC products is expected to offer exceptional electrical performance, the possibility of novel form factors, and unexcelled reliability, making it well suited for many demanding Army applications.
