Technology

Advanced hard carbon anodes for sodium-ion batteries.

Sodium-ion batteries are emerging as an important complement to lithium-ion technology, particularly for stationary energy storage, backup power and cost-sensitive mobility applications.

NexIB is developing a novel UK-based route to produce battery-grade hard carbon using engineered asphaltene-derived precursors. This approach has the potential to improve material sustainability, supply chain security and industrial manufacturability.
