Supercapacitors are electrochemical energy storage devices that promise fast charge-discharge rate, high power density, and long cycle life. However, low energy density, high cost, and safety risk of supercapacitors are yet to be addressed in order to deploy the technology into wholesale grid storage. This research project will design low-cost and high-performance electrode and electrolyte for supercapacitors.
Batteries are main storage systems in many applications such as electric vehicles, shipping, transportation, and utility backup power. With the recent breakthrough in the supercapacitor technology, it is predicted that supercapacitors will challenge the batteries in many of these applications since their power delivery is much faster than the batteries. The current chargers are designed based on the requirements of the batteries.
Storing electrical charge has been one of the top demands for human being during his lifespan. Nowadays, energy storage systems are among the most concern around the globe. The ability to provide a special class of electric energy storage devices that can complement or replace batteries and harvesting applications when high power delivery or uptake is required has drawn much more attention. With introducing double layer supercapacitors (DLEC) the demand for more rapid charge/discharge rates as compared with batteries has been increased.
