Soteria Battery Innovation Group is a technology company focused on improving the safety of lithium-ion batteries. Founded in 2017, the company’s mission is to make inherently safe batteries accessible to all by addressing the root causes of battery thermal runaway and fires. Soteria develops and licenses patented safety technologies designed to mitigate the risks associated with battery failures.
Operating through a global consortium and a Battery Safety IP Exchange, Soteria works with a broad network of industry participants. Their approach emphasizes system-level safety solutions, incorporating advanced materials and detection strategies to enhance battery reliability across various applications, from electric vehicles to portable electronics. This collaborative model aims to accelerate the adoption of safer battery technologies throughout the supply chain.
Battery Technology
Soteria Battery Innovation Group provides several proprietary technologies designed to increase the safety and performance of lithium-ion batteries. A key innovation is the Dreamweaver Separator, which utilizes aramid reinforcement to resist melting and shrinking at high temperatures, improving cell durability and cycle life.
Another significant technology is their Metallized Polymer Current Collectors (MPCCs). These current collectors are lighter than traditional metal foils and function as internal fuses. In the event of an internal short circuit, the MPCC burns out at the point of failure, localizing the issue and preventing uncontrolled current flow that can lead to thermal runaway. This technology enables improved safety while also contributing to higher energy density by reducing passive material weight.
Soteria also offers thermal insulation solutions, a venting detection system called Soteria Sense™, and develops enhanced cells with improved thermal stability and cycle life, such as Voltaplex Life™ cells.
Recent Projects
In recent activities, Soteria Battery Innovation Group has focused on addressing specific market needs. They recently filed a patent for a thermal insulation blanket designed for use in e-bike battery packs. This innovation aims to prevent the rapid spread of fire between cells in the event of failure.
In November 2024, Soteria launched the Soteria Sense™ Battery Vent Detection System, providing early warning of battery venting events. The company continues to develop industry guidelines, including an e-bike battery safety specification, to promote safer design and use of lithium-ion batteries. These projects highlight Soteria’s focus on practical safety solutions for diverse applications.
Investors
Soteria Battery Innovation Group has secured funding from various sources to support its technology development and expansion. The company has raised funding through venture capital and grants, including support from institutional investors like Keiretsu Capital. Additionally, Soteria has utilized crowdfunding platforms, such as StartEngine, to raise capital. This blend of institutional and public funding sources has supported the company’s growth and its efforts to bring advanced battery safety technologies to market.
