BCG Digital Ventures Collaborates with Unifrax and Clearlake to Advance Silicon Anode Technology for Lithium Ion Batteries


SiFAB™, Unifrax’s Patented Silicon Fiber Anode Battery Technology, Holds Breakthrough Potential in the Broader Transition to Clean, Renewable Energy.

LOS ANGELES and BUFFALO, NY—BCG Digital Ventures (BCGDV), the leading corporate innovation and business building arm of Boston Consulting Group (BCG), and Unifrax, a leading provider of high-performance specialty materials backed by Clearlake Capital Group, L.P., today announced that the two companies are collaborating on SiFAB™, Unifrax’s patented silicon fiber anode battery technology for improving energy density, accelerating charges, and lengthening battery life.

SiFAB, which can be added to existing battery production processes, addresses a critical barrier to mass adoption of electric vehicles and the broader transition to clean renewable energy. The technology also has wide-ranging implications for the future of electric vehicles, power tools, portable electronics, and grid storage — all of which can benefit from the superior performance, longer battery life, and reduced size and weight that SiFAB delivers.

After several years of R&D, Unifrax sought collaboration with BCGDV to validate SiFAB’s market opportunity and performance characteristics, establish competitive benchmarks, and confirm the company’s scale-up plans. The team is now focusing on commercialization, as Unifrax works toward production of SiFAB in early 2022. In a move to advance the building of thousands of tons of long-term manufacturing capacity, Unifrax recently announced plans to establish its first large-scale SiFAB manufacturing line, at its north-central Indiana facility.
