Scientists at the University of Cambridge are working intensively on a lithium oxygen (Li-O2) battery which will dramatically increase the range of an electric vehicle.

The main concern with today’s EV has to do with range anxiety and even though progress is being made regularly, not a lot of people are willing to sell their combustion engine-powered vehicles and go for a silent, emissions-free car. That could change eventually as University of Cambridge scientists have created a lithium oxygen battery that could have a ten times higher energy density compared to the current crop of lithium ion batteries.

Also known as lithium air batteries, these will enable a significantly higher range for electric vehicles that could actually get close to a conventional car. The good news doesn’t end here as scientists say the new battery pack will have a fifth of the weight and a fifth of the cost of current lithium ion batteries.

That being said, it’s still a work in progress as the researchers estimate it could take more than ten years before the lithium air batteries will be ready for mass production. The main issue right now is with the battery’s low ability to charge and discharge, but if they can fix this in the years to come, the battery will be more efficient and stable compared to a lithium-ion pack. The experts went on to specify it will have an efficiency rate of approximately 93% and will last for more than 2,000 recharges.
