Lithium-air batteries

Lithium-air batteries may be the short-term solution to lightweight and relatively efficient battery power. Major implications in terms of electric vehicles and handheld electronics.

From the link:

Yang Shao-Horn, an MIT associate professor of mechanical engineering and materials science and engineering, says that many groups have been pursuing work on lithium-air batteries, a technology that has great potential for achieving great gains in . But there has been a lack of understanding of what kinds of electrode materials could promote the electrochemical reactions that take place in these batteries.

Lithium-oxygen (also known as lithium-air) batteries are similar in principle to the lithium-ion batteries that now dominate the field of  and are a leading contender for . But because lithium-air batteries replace the heavy conventional compounds in such batteries with a carbon-based air electrode and flow of air, the batteries themselves can be much lighter. That’s why leading companies, including IBM and General Motors, have committed to major research initiatives on lithium-air technology.

For further reading here’s the MIT release that spawned this PhysOrg story.
