SCC55™ Sets a New Standard of Excellence

Rick Costantino, CTO

Rick has spent 20+ years developing products across the biopharmaceutical and chemical industries at companies such as Genentech, Alkermes, and Nastech. Prior to founding Group14, he served as the VP of Research and Development at EnerG2. With more than 60 U.S. patents and 50 publications, Rick earned his Ph.D. in Chemical Engineering from MIT.

SCC55™ solves a decades-old challenge for the battery industry.

Group14 is tirelessly working to help the world transition away from fossil fuel-based energy sources and inefficient batteries, developing new, sustainable energy technologies that dramatically increase energy density and radically improve charge times.

Our flagship product, SCC55™, is a stable silicon-carbon composite material, which holds up to five times the capacity of graphite and affords up to 50% more energy density than conventional graphite for lithium-ion battery anodes. Its unique hard carbon-based scaffolding keeps silicon in the most ideal form: amorphous and nano-sized.

We optimized SCC55™ to be a drop-in-ready solution that can blend with or fully replace graphite in the anode, powering silicon batteries across a spectrum of applications and products. This advanced battery technology will not only help usher in the electric vehicle era — but also an array of improved technologies in consumer electronics, grid storage, aerospace, and other forms of mobility.

SCC55™ is an elegant and stable combination of silicon and carbon that enables the next generation of lithium-silicon and solid-state batteries. Our material was designed to be easy to use, high performing, and manufactured at commercial scale.

SCC55™ is manufactured by a two-step process that we call Scaffold Prime™. And with this process, we’re able to produce our material, SCC55™, and scale it rapidly, which we do right here at our Battery Active Materials, or BAM factory, in Woodinville, Washington. Our material enables batteries — and the devices powered by those batteries — to last longer and charge faster.

If you look at the lithium-ion battery industry, there have been incremental improvements on the order of maybe a few percent per year, and that’s fantastic. But to get big improvements, you need many, many years. So with SCC55™, we can increase the energy density of the lithium-ion battery up to 50% and transform it into a lithium-silicon battery. So now, an improvement that would have taken decades, we can have that improvement today with SCC55™.
