Nano-silicon application：

1. Nano silicon wires made of nano silicon powder are used in the negative electrode material of rechargeable lithium batteries, or graphite is coated on the surface of nano silicon powder to be used as the negative electrode material of rechargeable lithium batteries, which increases the capacity and charge and discharge cycle times of rechargeable lithium batteries by more than 3 times;
2. Nano silicon is used in high temperature resistant coatings and refractory materials;
3. Nano silicon powder can be applied to coatings to form silicon nano films, which are widely used in solar energy;
4. Nano silicon and diamond are mixed under high pressure to form silicon carbide-diamond composite materials, which are used as cutting tools.

Storage conditions

This product should be sealed and stored in a dry and cool environment. It should not be exposed to the air for a long time. It should be prevented from agglomeration due to moisture, which will affect the dispersion performance and use effect. It should also be avoided from heavy pressure and contact with oxidants. It should be transported as ordinary goods.
