BASF and Group14 Technologies have introduced a groundbreaking commercial silicon battery solution that merges BASF’s Licity 2698 X F binder with Group14’s SCC55 silicon battery material. This collaboration aims to provide battery manufacturers with enhanced performance compared to conventional graphite anodes.
In testing, cells constructed with these combined materials demonstrated an impressive **1,000 charge cycles** while maintaining **80% capacity** under standard room temperature conditions. Furthermore, at elevated temperatures of **45°C**, these cells exceeded **500 cycles**, delivering nearly **four times the capacity** of traditional graphite anodes. This innovation addresses longstanding issues associated with silicon-based battery anodes, which tend to expand significantly during charging, leading to degradation over time.
BASF’s binder has been specifically engineered for silicon-rich anodes, ensuring the stability of electrodes under demanding conditions. Rick Luebbe, CEO and Co-Founder of Group14 Technologies, emphasized the significance of this partnership, stating, “The future of energy storage powered by silicon batteries is here, and our collaboration with BASF is driving mainstream adoption at an unprecedented speed. By combining technologies, we are empowering battery manufacturers to deliver high-performance, scalable silicon batteries more rapidly to meet today’s soaring energy demands.”
This collaboration effectively optimizes BASF’s binder technology alongside Group14’s SCC55 material, resulting in what both companies describe as a robust cycle life with improved performance characteristics. Group14 Technologies specializes in advanced silicon battery materials, while BASF focuses on producing chemical solutions, including battery binders. Dr. Dirk Wulff, Global Technical Battery Binder Manager at BASF, noted, “Silicon is now an attractive technology without the limitations of the past. By combining our expertise, we achieved an anode cell chemistry that not only meets but exceeds industry requirements.”
The solution is designed to be drop-in ready for current battery manufacturing processes, which could significantly lower the implementation barriers for producers interested in integrating silicon-based materials. Silicon anodes have the potential to store more lithium ions than graphite, resulting in higher energy density and faster charging capabilities in lithium-ion batteries. Both companies are targeting the expanding electric vehicle market, where enhancements in battery performance—specifically in charging speed, energy density, and durability—are crucial competitive factors for manufacturers.
