Electrochemical capacitors have demonstrated tremendous potential for high-energy, high-reliability use in HEVs and PHEVs, as well as in many other transportation and materials handling applications where regenerative capture of otherwise lost energy is required. However, this potential has been… More

Navy aircraft programs and upgrades will require advanced electrical energy storage devices that provide extraordinary power, for example one that can deliver 1500 W average power for 5 seconds at 1.5 V, be recharged at several hundred amps, then discharged and recharged repeatedly up to 10,000… More

We propose to develop processes and process flows to create optimized vertically-oriented graphene nanosheet electrodes, use these electrodes to fabricate prototype electric double layer capacitors (EDLCs), and demonstrate their superior electrical performance as compared with similar devices… More
