Soteria Battery Innovation Group Signs Exclusive License and Option for a Battery Safety Technology by Oak Ridge National Laboratory

The licensed technology is for electrodes and foils for lithium ion batteries that are designed to break in a pre-defined geometry when the battery is physically damaged, effectively isolating the damaged part.  This can minimize the associated generated heat and avoid thermal runaway, or uncontrolled increasing temperature, thus rendering the battery safe.

“This technology can dramatically improve battery safety upon mechanical, thermal and electrical damage,” said ORNL’s Jianlin Li, a principle investigator of the technology. “This can simplify battery design and lead to higher energy density and lower cost.”

Combining the technology with Soteria’s own current collector technology was selected in 2019 for a $750,000 DOE Technology Commercialization Fund project, “Li-on batteries with Safer Current Collectors,” with support from the DOE Office of Energy Efficiency and Renewable Energy, Vehicle Technologies Office.

The technology will be especially effective in vehicles, where physical damage can occur in automobile accidents and other
