REPORT: IBM working to develop 500-mile lithium-air battery pack
To reach this lofty goal, IBM's group is focusing on lithium-air technology, which uses lithium anodes electrochemically coupled to atmospheric oxygen through an air cathode. These batteries are thought to be ideal for EV applications due to their superior energy density – IBM's scientists say up to 10 times that of today's lithium ion batteries – and high specific energy.
Exciting technology to be sure, but IBM doesn't expect to know if these batteries will be commercially viable for another two years. By then, maybe some sort of fast charger will exist with a pipe big enough to transfer all that power into the battery in a reasonable amount of time.
