Hard Carbon (HC)

You are here:

Hard Carbon (HC) is recognized as a promising anode material with outstanding electrochemical performance for Sodium-ion batteries (SIBs). Hard Carbon (HC) is the state-of-art anode material for Sodium-ion batteries due to its excellent overall performance, wide availability, and relatively low cost. Tremendous effort has been invested by Indi Energy to elucidate the Sodium storage mechanism in HC, and to explore synthetic approaches that can enhance the performance and lower the cost.

Indi Energy has achieved world’s highest performance in Hard Carbon (HC) for Sodium-ion batteries, made from bio-waste / agricultural waste.
