Anode Material for Lithium-ion Battery BIOHARDCARBON KURANODE™

Main Features of KURANODE™

KURANODE™ is anode material classified in hard carbon, used for lithium-ion battery. It is made from ecofriendly natural plant as raw material. Hard carbon including KURANODE™ has better input and output performances, cycle performance and low temperature performance than graphite which is broadly used as anode material. Moreover, KURANODE™ has cost competitiveness and good handling property (less moisture absorption) incomparison with traditional hard carbon.

Features of Hard Carbon: Charge–discharge performance, Recyclability, Low‑temperature performance

Additional Features: Excellent cost performance, Low moisture absorption (compatible with water‑based binders)

①

Especially suitable for applications requiring regeneration capabilitysuch as automobile use.

②

Suitable as an anode material not only for lithium-ion batteries (LIBs) but also for lithium-ion capacitors (LICs) and sodium-ion batteries (SIBs / NaIBs).

③

Usable with water based binder (e.g. SBR/CMC) as well as solvent based binder (e.g. PVDF) thanks to its high moisture resistance.

Low Temperature Performance

Charge rate property at -20℃

Discharge rate property at -20℃

Even at low temperatures where graphite cannot charge or discharge, KURANODE® is capable of stable charge–discharge performance, including under high‑rate conditions.

HPPC

(Hybrid Pulse Power Characterization)

■ Cathode: NCM　■ Cell: Laminate type　■ Temperature: 25℃
■ Plotted maximum input/output pulse power for 10s of each SOC　■ Measured by Kuraray

Compared with graphite, which is commonly used as a negative‑electrode material, hard carbon offers superior charge–discharge (input/output) performance.
