High Performance Supercapacitors Utilizing Electroactive

and Conductive Polymers (ECPs)

Supercapacitors: Also known as Electric double-layer capacitors, (EDLCs), or

ultracapacitors, supercapacitors are electrochemical capacitors

that have high energy density in comparison to standard capacitors.

For example, a typical D-cell sized electrolytic capacitor will have a

capacitance in the range millifarads while supercapacitors are in the

farads. Supercapacitors aim to fill the gap between capacitors and

batteries.

Advantages over existing

technology:

• higher energy and power

• long cycle life

• lightweight

• cheaper to manufacture

• safer/easier to dispose Schematic of a supercapacitor

using Crosslinks ECPs

Supercapacitors from Crosslink

contain a ECP film which is,

• Metallically Conductive

(1000 S/cm)

• Solution Processable

• Mechanically and thermally

stable

Applications:

• Pulsed power: flash for cameras, cell phones and wireless

transmitters such as radio frequency ID tags)

• Energy Storage Systems: solar panels, wind turbines and

hybrid vehicles

Self-Detoxifying System

for Toxic Chemicals and Bacteria

Scope of Project:To develop a printed fabric system that slowly releases hydrogenperoxide (H2O2), a strong oxidant. This system will provide acontinuously regenerated supply of H2O2, in-situ, which can reactwith and destroy both toxic chemicals and bacteria.
