The race to decarbonise the global economy runs on batteries. From electric vehicles to the storage systems that make the distribution of renewable energy possible, the demand for better, cheaper and faster energy storage has never been more urgent.
For years, the paradigm in the battery sector has been a combination of lithium and graphite – the former to hold the electrical charge, the latter to act as the anode, facilitating the reaction.
You can find graphite in nearly 95 % of lithium-ion batteries today, but another material is increasingly challenging its dominance: silicon.
As an anode material, silicon can hold 10 times more lithium than graphite, meaning silicon batteries have the potential to perform at levels previously unseen.
One of the foremost innovators in the silicon battery sector today is Group14, a fast-growing company based in Washington, US.
With a busy year ahead for the company, Energy Digital spoke with Group14’ s CEO and Co-Founder Rick Luebbe to understand how this technology works, what it costs and whether it truly has the potential to redefine energy storage as we know it.

Rick is CEO and Co-Founder of Group14 Technologies, a battery materials company based in Woodinville, WA, bringing unmatched performance capabilities to the era of the lithium-silicon battery to power the electrification-of-everything era.
the graphite traditionally used in the anode with a silicon-carbon composite, dramatically increasing energy storage capacity and charging speeds while maintaining compatibility with existing battery manufacturing.
Group14 manufactures a silicon battery material, SCC55, that houses the silicon inside a porous, nano-carbon scaffold. This solves silicon’ s tendency to swell, because the microscopic pores accommodate expansion and contraction during charging and discharging.
