General name
Hard carbon (nongraphitizable carbon)
Sales format

KURANODE™ is a hard carbon anode material used for lithium-ion batteries. As a natural plant-based material, it helps to reduce environmental impact.


Especially suitable for applications requiring power, such as hybrid vehicles. Suitable as anode material not only for lithium-ion batteries, but also for lithium-ion capacitors and sodium-ion batteries.


Input/output and low-temperature performance

Wider interlayer spacing (d002) than graphite brings excellent lithium-ion diffusibility.

Cycle performance

Volume change associated with charge and discharge process is smaller than graphite. It contributes to a longer battery life.

High moisture resistance

Usable with water based binders such as SBR/CMC

Cost competitiveness

Cost competitiveness compared with traditional hard carbon
