Capacitor
A capacitor is an electronic device that stores charge and energy. Capacitors can give off energy much faster than batteries can, resulting in much higher power density than batteries with the same amount of energy. Research into capacitors is ongoing to see if they can be used for storage of electrical energy for the electrical grid.
