Researchers at the Department of Energy's Argonne National Laboratory have developed a new approach to increasing the capacity and stability of rechargeable lithium-ion batteries.

The technology is based on a new material for the positive electrode that is comprised of a unique nano-crystalline, layered-composite structure.
The new materials yielded exceptionally high charge-storage capacities, greater than 250 mAh/g, or more than twice the capacity of materials in conventional rechargeable lithium batteries. In larger batteries, the technology could be used in the next generation of hybrid electric vehicles and plug-in hybrid electric vehicles. Details of the new developments will be presented on Tuesday, May 8 at the 211th Meeting of The Electrochemical Society, being held in Chicago, May 6-10.
The presentation on "Anomalous Capacity and Cycling Stability of Layered-Layered Electrodes in Lithium Batteries" by Argonne researchers Chris Johnson, Naichao Li, Christina Lefief, Jeom-Soo Kim, Jeremy Kropf, John Vaughey, and Michael Thackeray, will be given by Chris Johnson.
