BASF and Group14 deliver silicon anode breakthrough for lithium-ion batteries

BASF and Group14 have unveiled a market-ready silicon anode solution capable of delivering nearly four times the capacity of graphite. Their drop-in technology is said to offer high durability and rapid scalability for next-gen EV batteries.

BASF and Group14 Technologies have unveiled a commercial-ready silicon anode solution designed to replace graphite in lithium-ion batteries, marking a key milestone for battery innovation in electric mobility. The drop-in approach combines BASF’s Licity 2698 X F binder with Group14’s advanced silicon-carbon material SCC55 – delivering a step-change in energy density, charge rates, and durability.

Targeted at the next generation of EV batteries, the solution is said to maintain 80 per cent capacity after over 1,000 cycles at room temperature. Under elevated thermal stress at 45°C, cells still exceed 500 cycles while offering nearly four times the capacity of standard graphite anodes.

BASF’s binder, specifically developed for silicon-dominant anodes, provides structural integrity and cycle stability under demanding conditions. Group14’s SCC55® offers a scalable, high-capacity silicon alternative engineered for drop-in integration into existing lithium-ion platforms.

“The future of energy storage powered by silicon batteries is here,” said Rick Luebbe, CEO of Group14. “Our partnership with BASF is helping bring high-performance, scalable batteries to market faster than ever.”

Dr. Dirk Wulff, Global Technical Battery Binder Manager at BASF, added: “Silicon is now an attractive technology without the limitations of the past.”
