capacitors

While speaking at the Cleantech Forum in San Francisco, CA last week, Elon Musk, chief executive officer of Tesla, said he's willing to bet against batteries to be the technology that finally delivers the breakthrough that electric-drive vehicles need to become mainstream. Earth2Tech quotes Musk ...

Want a battery that recharges insanely fast and can hold more than ten times the energy of a lithium-ion battery? Then get in line for one of the digital quantum batteries that are being developed discussed at the University of Illinois at Urbana-Champaign. And don't forget to pack a lunch, ...

While batteries make most of the headlines when it comes to the energy storage requirements of electric cars, the capacitor could be an exciting and viable alternative. Unlike batteries, which store chemical energy and make it available for use as electrical energy, capacitors store energy in the ...

In a recent article in Popular Mechanics, editor Mike Allen declared himself a fan of ultracapacitors for hybrid cars. He explains how he visited Honda's development facilities 15 years ago and found himself testing a mild hybrid that used an ultracapacitor to store energy. However, we all know ...

One of the means that electrically powered vehicles used to maximize their range is regenerative braking where the kinetic energy of the vehicle is recaptured during deceleration and than released during acceleration. The problem is that most batteries can't absorb energy quickly enough to capture ...
