IBM looking to put lithium-air batteries on the road

By - April 26, 2012 1 Picture
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. Read More

Last year MIT researchers reported improving the efficiency of lithium-air batteries through the use of electrodes with gold or platinum catalysts. MIT News is now reporting that in a continuation of that work, researchers have been able to further increase the energy storage capacity of lithium-air batteries for a given weight by creating carbon-fiber-based electrodes.

Lithium-air batteries offer three times the energy density

By - April 5, 2010 2 Pictures
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
