2. 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.
