BASF and Group14 Technologies have introduced a commercial-ready silicon anode solution designed to significantly boost the performance of lithium-ion batteries.
The technology, which combines BASF’s Licity 2698 X F binder with Group14’s silicon-carbon material SCC55, is aimed at next-generation electric vehicles and is said to offer nearly four times the capacity of traditional graphite anodes.

The drop-in solution is engineered for seamless integration into existing lithium-ion battery manufacturing processes. It is designed to maintain 80% capacity after over 1,000 charge cycles at room temperature and over 500 cycles at 45°C, a benchmark indicating enhanced thermal durability. According to the companies, this advancement promises increased energy density, faster charging capabilities, and greater longevity.
BASF’s specially developed binder enhances structural integrity and supports cycle stability under the mechanical stress typical of silicon-dominant electrodes. Group14’s SCC55 material offers a scalable pathway for battery makers to transition from graphite to silicon-based technologies without the need for fundamental changes in production lines.
