BASF and Group14 Technologies have developed a market-ready, highly durable silicon battery solution using commercially available materials: BASF’s Licity 2698 X F binder and Group14’s advanced silicon battery material, SCC55. The solution has four times higher capacity to replace graphite in lithium-ion batteries, according to Group 14.
The drop-in-ready solution aims to enhance the performance of batteries with silicon-dominant anodes, delivering faster charging and higher energy density, with extreme durability, even in the most challenging conditions. Under standard conditions at room temperature, test cells typically exceed 1,000 cycles with 80% of capacity remaining. However, at a temperature of 113°F (45°C), the BASF and Group14 cells achieved over 500 cycles while providing nearly four times the capacity of a traditional graphite anode.
“The future of energy storage powered by silicon batteries is here, and our collaboration with BASF is driving mainstream adoption at unprecedented speed,” said Rick Luebbe, CEO and co-founder of Group14. “By combining technologies, we are giving battery manufacturers the power to deliver high-performance, scalable silicon batteries faster than ever to help meet today’s soaring energy needs.”
BASF’s Licity 2698 X F binder was developed specifically for silicon-rich anodes and can stabilize the electrode in the most demanding conditions. The collaboration optimizes BASF’s latest binder with the capabilities of SCC55, ensuring robust cycle life and transformational performance.
“Silicon is now an attractive technology without the limitations of the past,” commented Dr Dirk Wulff, global technical battery binder manager at BASF. “By combining our expertise, we achieved an anode cell chemistry that not only meets but exceeds industry requirements.”
“Strong and capable lithium batteries are crucial for electric mobility’s mass adoption. Our BASF dispersions business provides Licity binders that push this technology further,” added Prof. Dr Thomas Schiele, vice president in charge of BASF’s battery binder business in EMEA.
