UK scientists have created a battery that may greatly increase electric cars’s range, but it is a decade away from production.
The electric cars have always been viewed with some reluctance regarding their limited range. But this perception might change in the near future as UK scientists have found a new battery technology that could replace the lithium oxygen ones. Researchers at the University of Cambridge reported the design of a lithium oxygen battery prototype that may overcome the current limitations in terms of power, size, price and, most importantly a much longer range between charges. The scientists believe the energy density in such lithium oxygen batteries could be ten times higher than a regular lithium ion battery. It is thought that this new battery, also called lithium air battery, will be able to extend the EV’s range in such manner that will eventually reach that of gasoline engines.
Other major benefits, researchers say, are the low weight and production costs. New batteries may also be a fifth of the cost and a fifth of the weight of current lithium ion batteries. But we’ll have to wait at least ten years, as researchers said, before a practical lithium oxygen battery is ready for mass production. And this is caused by the current battery’s low ability to charge and discharge. This is not the only research in this direction, but in contrast to others the Cambridge prototype uses lithium hydroxide rather than lithium peroxide in its construction. The result is a more stable and efficient battery that can be recharged more than 2,000 times and currently achieves an efficiency rate of about 93 percent.
