Lithium-Silicon as the Next Generation Battery Material for Long-Term Energy Storage 

Rick Costantino, Co-Founder and CEO • Group14 Technologies 

Winter storms in Texas left millions of Americans without power for several days and exposed the need for long-term energy storage solutions. Moving forward, it is imperative that utilities are equipped with the advanced battery-powered energy storage systems to create a more nimble and reliable grid. While conventional lithium-ion battery technology is only capable of incremental improvements year-over-year, new lithium-silicon battery technology offers a high-performing energy storage solution for a variety of applications, including grid storage under strain during extreme weather conditions. By replacing graphite in the anode with a silicon-carbon composite anode material, lithium-silicon battery technology unlocks increased energy density and cycle life. Lithium-silicon is drop-in ready and can fully displace incumbent graphite, allowing battery manufacturers a 50 percent boost in energy density without any increase in capital expenditures for manufacturing.

During this presentation, we will discuss the benefits to lithium-silicon as the next generation of energy storage solutions that are achievable today. In addition, Rick can share the challenges of working with silicon and how a flexible carbon scaffold with intra-particle void space and low surface area keeps silicon in its ideal form: amorphous, nano-sized and carbon-encased. 

 

Rick Costantino is CTO and co-founder of Group14 Technologies, founded in 2015 to commercialize the company’s lithium-silicon battery technology to meet the world’s increasing demand for advanced energy storage. Rick has over 30 years of experience developing stable, high-performance products at the molecular level, spanning chemical and biopharmaceutical industries for companies such as Genentech, Alkermes, and Nastech. Rick’s efforts have culminated in numerous commercial products, from marketed therapeutics to electrode materials for advanced ultracapacitors and lead acid batteries. Rick holds more than 50 U.S. patents and has over 50 publications. Prior to founding Group14, he served as the VP of Research and Development at EnerG2. Previously, Rick served as the CSO of delivery at MDRNA Inc. and CSO at G2B Pharma. Rick holds a B.S. and M.S. in Chemical Engineering from Johns Hopkins University and a Ph.D. in Chemical Engineering from M.I.T.
