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


GREENVILLE, S.C., Sept. 30, 2020 /PRNewswire/ — Soteria Battery Innovation Group (BIG) has exclusively licensed and optioned a technology developed by the Department of Energy’s Oak Ridge National Laboratory designed to eliminate thermal runaway in lithium ion batteries due to mechanical damage. The technology complements Soteria’s existing battery safety technology.

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 mechanical events. The market for batteries for electric vehicles is expected to grow to over 2,000 gigawatt hours by 2030 according to Bloomberg New Energy Finance, resulting in over $200 billion in battery consumption.

Soteria BIG is dedicated to eliminating lithium ion battery fires. “While our initial innovations to eliminate battery fires came from our own labs, our vision is bigger than we could accomplish on our own. This technology enables us to deliver safety in physical damage situations in large, high power batteries that our original technology might not have addressed,” said Carl Hu, Soteria BIG’s chief technology officer.
