The technology is based on a new material for the positive electrode that is comprised of a unique nano-crystalline, layered-composite structure.
Argonne scientists said they used an active component that provides for charge storage, which is embedded in an inactive component that stabilizes the structure.
In testing, the new materials yielded exceptionally high charge-storage capacities more than twice that of conventional rechargeable lithium batteries. In addition, by focusing on manganese-rich systems instead of the more expensive cobalt and nickel versions of lithium batteries, overall battery cost is reduced, the researchers said.
Potential applications range from consumer electronics, such as cell phones and laptop computers, to hybrid electric vehicles.
The new technology was presented Tuesday in Chicago during the 211th meeting of The Electrochemical Society.
