Organic material for high-performance and rapidly-charging pseudocapacitors

This technology is an organic composite material that can be used for high-capacitance, high-current-density and rapidly-charging energy storage devices.

Unmet Need: Material for high-power and efficient energy storage

Conventional methods for energy storage rely on metal interfaces to connect energy sources to energy sinks and are limited in power density, heavy and expensive. Emerging solutions suffer from unreliability and low power output. High-energy density, lightweight, low cost and explosive-safe materials are needed for realizing efficient energy storage for many potential applications, including electrically-powered transportation and implementation of renewable energy.

The Technology: Organic capacitor material made from industrial dye

This technology is a material for pseudocapacitors composed of two organic materials, perylene diamide (PDI), an industrial available dye, and hexaazatrinaphthylene (HATN). The material is synthesized using relatively simple reactions, and is robust and lightweight. The material demonstrates superior capacitor properties capable of reaching 650 F/g at rates of 5 A/g. As such, this technology can potentially be used to fabricate stable and high-power-density energy storage devices.

This technology has been validated with a prototype two-electrode electrochemical cell capacitor.
