Lithium-air batteries offer three times the energy density

Lithium-air battery technology looks to have a big future. With the potential of providing energy densities up to three times that of the conventional lithium-ion batteries found in just about every portable consumer electronics device going around (not to mention the incoming wave of electric vehicles), many companies, including IBM and General Motors are pursuing work on lithium-air batteries. Now researchers at MIT have made a breakthrough that could help make the commercial development of lightweight rechargeable batteries a reality. Read More

If you haven’t previously heard of TuneBug, that’s because it is a new company and although its portable speaker solutions were shown at CES 2009, they are only just now making their way to market.
