Product Detail

CAS No.:  7440-21-3 (Silicon), 7782-42-5 (Graphite)

Thanks to ACS Material’s widespread expertise, we are able to offer researchers and engineers at the finest institutions around the world an expansive range of high-quality products and solutions for lithium-ion batteries. One example is our Si/C composite anode material. This innovative material precisely integrates silicon-based materials with our high-performance graphite to significantly boost anode capacity ideal for use in varied high-power applications.

Carbon = Performance

The carbon structure enables outstanding electrochemical performance features such as high coulombic efficiency and an improved life cycle.

Silicon = Power

Adding silicon to the anode results in increased gravimetric and volumetric energy density as well as rapid charging capabilities over and above other comparable materials commonly used in high-energy applications.

ACS Material is pleased to provide high-quality Si/C composite anode materials to our customers around the world. These materials, along with all our nanomaterials, are produced using the latest technological advancements and conform to the most rigorous standards for purity and consistency. Our reputation for exceptional quality makes us the leading trusted supplier for nanomaterials for research universities, national laboratories, and innovative companies worldwide.

Application Fields

Lithium-ion Battery Anode Material:

The theoretical specific capacity of the graphite anode material is 372mAh/g, and the graphite anode material with better performance can reach 360mAh/g. But the Si/C Composite anode materials of ACS Material, the current capacity of these two products are 450mAh/g and 500mAh/g, which means that the mileage could be increased a lot. Cycle performance can reach 1500 cycles, and capacity retention rate can reach 80%. This product has achieved industrialization ton scale, and has been applied in some well-known factories.
