Current obstacles
- Demand timingSlower EV sales and trade uncertainty delayed customer orders, so the Moses Lake plant ramps more slowly.
Physics limits
- Silicon swells about 300% when fullEach silicon atom can bind up to 3.75 lithium atoms, about 10× graphite's capacity per gram (3,579 vs 372 mAh/g), but the crystal swells ~300%, stressing particles every cycle.
- Every crack eats lithiumFresh silicon surface reacts with electrolyte, forming a film that traps lithium. Swelling cracks that film each cycle, so lithium is lost faster than with graphite.
How it works
A porous carbon sponge
Group14 first makes a carbon scaffold full of nanometre-scale pores, like a hard sponge with empty space inside.
Silicon grown inside the pores
Silane gas breaks down inside the pores, filling them with tiny amorphous silicon particles, which hold far more lithium than graphite.
Room to swell
Because the silicon sits in pores, its swelling on charge is absorbed inside each particle instead of cracking the electrode.
A powder for existing lines
SCC55 is a powder cell makers mix into anodes on their current equipment, replacing some or all of the graphite.

About Group14 Technologies
Group14 Technologies
SCC55 silicon-carbon anode material
Group14 (founded 2015, near Seattle) makes SCC55, a silicon-carbon powder that replaces some or all graphite in battery anodes so cells hold more energy. It owns a factory in South Korea and is building a bigger one in Moses Lake, Washington.
- Closed a $463M Series D in August 2025 led by SK Inc., and took full ownership of its Korean factory.
- SCC55 ships to 100+ battery and device makers, mostly for electronics and EV development.
- Its Moses Lake plant (BAM-2) hit delays, a July 2025 staff cut and January 2026 furloughs; full production expected in 2026.
