Sila Nanotechnologies has produced commercial-format 4680 cells using its silicon-dominant anode that deliver 450 Wh/kg gravimetric energy density—a 50% improvement over conventional graphite-anode cells in the same form factor. The cells completed 500 cycles retaining 92% capacity, addressing durability concerns that previously limited silicon anode adoption.
Scaling Production
Sila’s Moses Lake, Washington facility has begun mass production of its silicon anode material, with annual capacity sufficient for 100 GWh of battery production. Mercedes-Benz has confirmed the technology will debut in its 2027 EQS flagship, delivering over 800 km of real-world range.
“Silicon anodes have been the industry’s white whale for a decade. Achieving 450 Wh/kg in a standard automotive cell format at production scale is a genuine breakthrough.”—Gene Berdichevsky, CEO, Sila Nanotechnologies
