Supercomputing time awarded to design transformational lithium air battery
Oak Ridge 26 January 2010 24 million hours of supercomputing time out of a total of 1.6 billion available hours at Argonne and Oak Ridge National Laboratories have been awarded to investigate materials for developing lithium air batteries, capable of powering a car for 500 miles on a single charge. Through the Innovative and Novel Computational Impact on Theory and Experiment (INCITE) programme, a research team including scientists from Oak Ridge National Laboratory, Argonne National Laboratory and IBM will use two of the world's most powerful supercomputers to design new materials required for a lithium air battery. Lithium-ion batteries, used in today's emerging plug-in hybrid electric vehicles, currently have a range of approximately 40 to 100 miles.

The calculations will be performed at both Oak Ridge and Argonne, which house two of the world's top ten fastest computers.

Oak Ridge National Laboratory Director Thom Mason said the battery project was the result of two visits to Oak Ridge in 2009 by IBM's vice president of research. "From those discussions, it became apparent that our partnership had many of the unique capabilities needed to tackle a scientific problem as important and challenging as increasing by more than a factor of 10 the energy stored in batteries for transportation."

"Argonne is committed to developing lithium air technologies", stated Argonne Director Eric Isaacs. "The obstacles to Li-air batteries becoming a viable technology are formidable, but the modelling and simulation capabilities of DOE's supercomputers will help us accelerate the innovations required in materials science, chemistry and engineering."
