Researchers Making Progress on Lithium-Air Batteries
Researchers from the University of Rome Sapienza (Italy), Argonne National Laboratory (United States), and Hanyang University (South Korea) have shown that the construction of lithium-air batteries without lithium metal is possible. A lithiated silicon-carbon anode can be used instead. As is the case with many new technologies, there are drawbacks to this one.
Two drawbacks are that such batteries have a lower capacity and a lower voltage than normal lithium-air batteries. However, the new battery is safer and has a greater energy density than lithium-ion batteries.
Lithium-air batteries are being sought by multiple organizations, including IBM, due to the fact that they have the potential to store a stunning 11,140 Wh/kg.
