Elon Musk, CEO of Tesla MotorsElon Musk, CEO of famed motor company Tesla, admits he believes that the long term war of energy in vehicles would be won by capacitors, not batteries. An ironic statement, coming from the man whose business currently utilizes numerous lithium-ion batteries for electric vehicles. It's also a statement with a lot of weight behind it, considering the other accomplishments Musk has in his belt (including having a hand in the creation of PayPal).

"If I were to make a prediction, I'd think there's a good chance that it is not batteries. but capacitors," stated Musk recently while at the Cleanteach Forum in San Francisco.

Currently, batteries continue to be a leading resource for energy throughout the world. Musk's statement, however, is backed by the knowledge behind capacitors and ultracapacitors. For example, unlike batteries, they can withstand more charge / discharge cycles.

More research is needed behind capacitors and ultracapacitors, and before that happens, batteries will continue to provide the energy needed for many electronic devices. But perhaps one day, Musk's prediction that capacitors "will supercede" batteries will come true.
