Researchers have developed a new technique to produce large-scale graphene current collectors for lithium-ion batteries using a scalable method.
The graphene foils produced through this method have extraordinary thermal conductivity over 10 times higher than copper and aluminum collectors currently used.
This high thermal conductivity improves battery safety by efficiently managing heat and prevents overheating which can cause thermal runaway failures.
The graphene foils are also flexible and can bend over 100,000 times while maintaining high electrical conductivity.
The researchers demonstrated producing foils from meters to kilometers in length with customizable thicknesses.
Safer, more efficient batteries using these graphene foils can accelerate electric vehicle adoption and utilization of renewable energy by addressing safety and efficiency needs.
This innovation represents a major advancement in energy storage technology that can contribute to a more sustainable energy future.
