Company Overview
About Soteria Battery Innovation Group
Soteria Battery Innovation Group (Soteria BIG) is a Greenville, South Carolina-based battery safety technology company operating at the intersection of materials science, manufacturing, and intellectual property licensing. Founded by Bob Galyen and other battery industry veterans, Soteria BIG has developed patented battery component technologies — specifically thermally stable separators and metallized film current collectors — designed to eliminate the risk of thermal runaway in lithium-ion batteries without compromising energy density or performance. Thermal runaway, the uncontrolled exothermic chain reaction that causes lithium-ion batteries to catch fire or explode, is the primary safety hazard in EV battery packs, grid energy storage systems, consumer electronics, and aerospace battery applications.
Business Model & Competitive Advantage
Soteria BIG operates an industry consortium model rather than a direct manufacturing model — licensing its patented technology to battery manufacturers, separator producers, and OEMs globally, and convening a consortium of member companies (including battery cell manufacturers, electric vehicle OEMs, and component suppliers) to accelerate the adoption of inherently safe battery materials across the supply chain. The consortium structure is designed to drive industry-wide standardization around safer battery component materials, creating a coalition that can influence regulatory and OEM specification requirements for battery safety globally. Members gain access to Soteria BIG's IP portfolio, technical development support, and a collaborative R&D framework for advancing safe battery manufacturing.
Competitive Landscape 2025–2026
The company's thermally stable separator technology uses a polypropylene-based material that maintains structural integrity at temperatures where conventional polyethylene or polypropylene separators melt — preventing the internal short circuit that triggers thermal runaway. Its metallized film current collector replaces the thick copper and aluminum foil current collectors in conventional cells with thin vacuum-metallized films that interrupt current flow in the event of a puncture or crush — providing a passive safety response built into the cell structure rather than relying solely on battery management systems. These component-level safety features are complementary to existing BMS and pack-level safety engineering.
