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.
Lithium-ion battery cells are prepped for testing at Argonne’s Electrochemical Analysis and Diagnostics Laboratory. With the lab’s state-of-the-art, custom-built equipment, simulations are performed to provide information on battery characteristics such as life cycle and calendar life.

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.
