Unique Material May Allow Capacitors to Store More Energy

Imagine an electric car with the same acceleration capability as a gas-powered sports car, or ultrafast rechargeable “batteries” that can be recharged a thousand times more than existing conventional batteries. According to physicists at North Carolina State University, all of these things are possible, thanks to their research on a polymer – or plastic material – that when used as a dielectric in capacitors may allow the capacitors to store up to seven times more energy than those currently in use.
