New capacitor research could increase capacities by seven times
This is good news for the electric and hybrid car industry, as capacitors are a possible alternative to batteries. Unlike batteries, which use a chemical reaction to release their stored energy, capacitors use no chemicals and are capable of storing and releasing a given amount of energy quickly. The problem is that capacitors generally store less energy than batteries. This potential, but untested breakthrough could alleviate some of that deficiency, allowing the capacitor to store more energy while still enabling that energy to be charged and discharged rapidly. EEStor is a name that has been thrown around on our blogs, as they claim to have a capacitor based system which rivals expensive batteries in power output, and possibly at less cost. We'll keep our ears and eyes open for more capacitor news, and we'll be sure to pass it along.
