Since launching and developing the Battery 500 Project, IBM believes it can produce a car battery than can travel 500 miles
IBM designed a battery that produces power by taking in oxygen and then recharges by expelling oxygen.
Because it is driven by the outside air, such a battery can be significantly smaller and lighter than traditional lithium ion batteries, providing a much longer life per square inch.
Researchers have long explored this sort of “lithium-air” battery, but IBM’s demonstration shows it can actually be built.
