Grat-Power™ SiGP anode
Grat-Power™ SiGP anode products
BGT is addressing the consumer demands for smaller electronics and sustainable power solutions by revolutionizing electrical energy storage technologies through our graphene-enhanced energy storage product line known as Grat-Power™. Grat-PowerTM SiGP, our first energy storage product to market, offers drastic performance improvements – 5x the capacity of existing graphitic anodes.
Our newest product, SiGP, is a composite anode active material combining the high capacity of silicon-based intermetallic alloys with the excellent conductivity and flexibility of layered graphene sheets.
Silicon demonstrates theoretical gravimetric and volumetric capacities beyond that of any know material making it a revolutionary anode additive. The flexible and robust graphene matrix eliminates the performance degradation associated with silicon monolithic anodes and offers the most competitive power characteristics.
- 30% increase in cycle efficiency
- Fully configurable and thin as a piece of paper
- High-uniformity in particle size and distribution
- Eco-conscious proprietary manufacturing processes
