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
