IBM’s Lithium Air battery

The batteries currently used in electric cars have the same limitation as the magnetic tapes. If you want more mileage on a single charge, you will have to pack more batteries into the vehicle.

That is where IBM’s next generation Lithium- Air battery technology will play. It can power a car for 500 miles on a single charge.

The battery generates electricity from a reaction between Lithium and Oxygen ions and it will be much denser and can store more than the existing Lithium-ion batteries.

IBM plans to produce a working prototype next year and is collaborating with several labs on the project.
