Company Description
Soteria Battery Innovation Group (BIG) is dedicated to enabling inherently safe lithium-ion batteries through two licensable technologies and an open-innovation platform. Advanced global companies are implementing heavy and expensive techniques (flame retardants, cooling systems, steel boxes) to contain the potential for thermal runaway, and the damage that occurs when an event happens. Even with these advanced techniques, dangerous and costly thermal runaway events can still happen. The Soteria architecture addresses the root cause of thermal runaway inside lithium-ion cells with thermally stable separators made from advanced fibers and metallized film current collectors that are engineered to stop the flow of current under the giant current densities that lead to lithium battery fires. The architecture provides the same electrical protection as a fuse on the inside of the battery. Soteria formed an open-innovation consortium of industry experts working together towards a common goal. Soteria members at each level of the supply chain (from raw material providers to end-users) are applying their expertise towards commercial success.
Product Highlight
The Dreamweaver separator, produced on specialty papermaking equipment, blends cellulose nanofibers and aramid fibers (think Kevlar or Twaron) that are stable to 500°C. The separator brings more stability while also wetting out much faster than conventional separators. It also acts as a getter for water in the battery, resulting in increased cycle life. With three global licensees, the Dreamweaver separator is commercially ready for your application today.
Produced through physical vapor deposition, the aluminum and copper metallized films burn out like a fuse around an internal short, isolating it and allowing a cell to continue functioning after damage. Plus, the current collectors remove roughly 80% of the metal of a traditional foil, increasing gravimetric and volumetric energy density. Having now been produced in production quantities, the current collector is ready for your development projects.
