Lithium-Air Batteries


Lithium-oxygen breakthrough clears the air for boosted batteries

Boasting an energy density similar to that of gasoline, lithium-air (or lithium-oxygen) batteries may one day prove the panacea for the range-anxiety associated with electric vehicles. But first there are a number of challenges that need to be overcome, one of which is the unwanted buildup of lithium peroxide on the electrode which hampers this type of battery's performance. Scientists have now figured out a way that this mess might be avoided – an advance they say could lead to batteries with five times the energy density of those currently available.Read More


More hurdles jumped on path to a practical lithium-air battery

With theoretical energy densities as much as 10 times that of current lithium-ion batteries, lithium-air (or lithium-oxygen) batteries hold tremendous potential for storage of renewable energy and use in mobile devices and electric cars. Although a practical lithium-air battery is still some years from becoming a commercial reality, researchers at the University of Cambridge have developed a working laboratory demonstrator that shows how many of the problems holding back the development of lithium-air batteries could be overcome.

IBM looking to put lithium-air batteries on the road

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

IBM's annual list of five innovations set to change our lives in the next five years

IBM has announced its fifth annual Next Five in Five – a list of five technologies that the company believes “have the potential to change the way people work, live and play over the next five years.” While there are no flying cars or robot servants on the list, there are holographic friends, air-powered batteries, personal environmental sensors, customized commutes and building-heating computers.Read More

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
