Argonne materials scientist Swati V. Pol loads an in-situ lithium-ion battery into the low-energy resolution inelastic X-ray (LERIX) system at the Advanced Photon Source. This multi-element X-ray scattering instrument is helping Argonne researchers to understand the fundamental mechanisms that limit the performance of batteries.
These unique glass chambers allow Argonne researchers to conduct controlled environment testing of lithium-oxygen batteries. Created by Argonne glassblower Joe Gregar, the chambers are modeled after cells being used by Professor Peter Bruce's research group at University of St. Andrews, Scotland.

Testing ensures that the super-conducting undulator for the Advanced Photon Source upgrade will meet the high-precision requirements needed to generate the world's brightest X-rays above energies of 25 keV.
Argonne battery researchers (from left) Khalil Amine, Chris Johnson, Sun-Ho Kang and Mike Thackeray flank a continuously-stirred tank reactor used to produce scaled-up quantities of cathode materials for lithium-ion batteries. Thackeray, Johnson, Amine and Jaekook Kim (not pictured) are co-inventors of a revolutionary cathode material used in the battery that powers GM's Chevrolet Volt.

Jennifer Salazar is a Coordinating Writer and Editor in Argonne’s Computing, Environment and Life Sciences directorate. "I've found that our researchers want to share what excites them and communicate it to others in the wider research community or to the public, and this offers a great environment for a writer," she said.
Nuclear engineer Laural Briggs reviews pressure distribution results from a 217-pin fuel assembly simulation. The simulation was computed by Argonne's Nek5000 large eddy simulation tool on the IBM Blue Gene/P Intrepid supercomputer.
Argonne scientist Ira Bloom examines a metallographic sample using an optical microscope to determine its microstructure in the laboratory's Battery Post-Test Facility. This information helps researchers learn what chemical and physical changes have occurred during the aging of battery materials.
