IBM's lithium-air battery uses oxygen from the air to react with lithium ions and generate electricity
One of the main challenges faced by the Electric Vehicle (EV) industry is so-called “range anxiety.” Current lithium-ion batteries will provide a range of about 100 miles (161 km), limiting the commercial adoption of EVs in a market accustomed to the range and supporting infrastructure of gasoline-powered vehicles. If existing lithium-ion batteries were scaled up to match the range capacity of gas-powered vehicles, they would be unfeasibly large and heavy. Lithium-air batteries, which have the potential to provide energy densities that rivals traditional gasoline-powered engines, are seen as a possible solution. IBM has been researching such batteries and recently announced that it's bringing two companies with experience in electric vehicle materials onboard to aid in their development.
