Electrochemical Analysis and Diagnostics Laboratory Facility

The EADL provides reliable, independent, and unbiased evaluations of battery performance and life, which serve as progress measures for DOE and U.S. Advanced Battery Consortium projects.

Argonne has a long history of conducting independent battery performance and life studies for the U.S. Department of Energy (DOE), dating back to the early 1970s. The EADL can test everything from small cells for consumer electronics to full-size electrical vehicle batteries. The EADL can test cells and batteries to any profile using custom design hardware and software. Also, it possesses the ability to test over a wide range of temperatures, from well below ambient to well above ambient temperature, using environmental chambers to house the test items (from cells to full-size batteries). We routinely evaluate contract and benchmarking deliverables for the U.S. Advanced Battery Consortium (USABC), USDrive, and DOE.

The methods used accelerate the performance degradation process, enabling the collection of data in a relatively short amount of time. These data are then used for modeling and life estimation.
