In order to be able to benchmark our new developed materials and processes, a shared battery test lab has been set up and equipped with state-of-the-art characterization instruments, such as a 32 channel Maccor battery cycler with temperature control chambers, an 8 channel Solartron frequency response analyzer, a portable Gamry potentiostat, and a large glove box with a video microscope. Each of these instruments can be expanded to accommodate a larger number of test stations as demand grows. The portable potentiostats will be used for off-site experiments at SNS, the electron microscopy labs, and synchrotron and X-ray diffraction labs. The video microscope will be used to assemble liquid flow cells for TEM and SEM characterization of critical battery materials and interfaces. Basic battery fabrication equipment and materials, such as a coin cell crimping machine, will also be available.

- Thermophysical Measurements and Thermal Runaway Characterization
Lithium-ion batteries are used widely in mobile applications due to their high-energy density, a feature that makes them attractive for plug-in hybrid and all-electric vehicles. However, high-energy density has important safety implications and Li-ion batteries are prone to thermal runaway. Therefore, studies on battery safety, especially under conditions leading to internal short and thermal runaway, are critical to enable the widespread deployment of Li-ion batteries in transportation applications. The goals of this project are to develop models to assess the propensity of cells and batteries to thermal runaway events; to establish experimental verification of mechanically induced internal short circuit; and ultimately to enable the design of robust, safe batteries. This project brings together ORNL’s unique capabilities in materials science and engineering and advanced computing that will position ORNL as a leader in the development of technologies that ensure the safety of energy storage devices for stationary and mobile applications, including hybrid electric and plug-in hybrid electric vehicles.
