Reducing the cost of secondary batteries is essential for the popularization of electric vehicles. In order to solve this problem, it is necessary to reduce the cost of battery materials.

Among the four battery materials, graphite has been generally used as the main material for anode materials, but silicon is attracting attention as an alternative material for increasing the capacity of secondary batteries.

In order to use silicon as an anode material, nano-sized materials are needed. As a means to provide these ultra-fine-sized raw materials, waste sludge generated from silicon ingots for solar cells or semiconductors is recycled and used as a cathode material for secondary batteries. .

If it is possible to provide recycled raw materials with uniform particles of high purity raw materials, it will have excellent cost competitiveness, which makes it possible to provide low-cost secondary batteries, which in conclusion can play a big role in popularizing electric vehicles.

Therefore, our products can provide high-quality silicon powder at low cost.
