High Energy and Power Density ALD-Enabled Devices

Envisioned Navy applications ranging from shore-based microgrids to directed energy weapons pose energy storage performance, cost, and scalability requirements that far exceed the capabilities of today"s technologies. Electric double-layer capacitors (EDLC) can meet most power demands ($/kW and kW/L) but cannot be used where high energy density is also required. As such, there is a need for a new electrochemical technology that can meet both high-energy and high-power demands using cost-effective materials. To address this need, ADA Technologies, Inc. (ADA) proposes to partner with PneumatiCoat Technologies, a leader in scalable atomic layer deposition (ALD) coatings, to develop an EDLC with high surface area nanocomposite electrodes modified with high dielectric constant metal oxide coatings. The resulting device will be readily scalable, consist of low-cost components, and be effective for tens of thousands of cycles across a wide operational temperature range.
