Ultracapacitors are passive electronic components that, unlike batteries, store energy by physically separating positive and negative charges. They offer high power densities and provide significant energy storage capacities. Capacitance, a measure of energy storage ability, is typically expressed as C = K A/D, where A is the area of the electrodes, D is their separation, and K is a function of the dielectric between the electrodes. The formula yields a result in farads (F), but a farad is so large that the most commonly used values are expressed in microfarads (µf = 10-6F) or picofarads (pf = 10-12F). Applications for ultracapacitors include fuel cells for hybrid vehicles and robotic motion control systems. |
