Graphite products for the purification of graphite negative electrode materials

The artificial graphite powder and natural graphite powder used as anode materials for lithium-ion batteries need to be purified. There are two main purification processes, namely, gas (chlorine or Freon gas) purification and high-temperature purification, with the increasingly stringent environmental requirements, the application of gas purification process is decreasing, while the application of high-temperature purification process is increasing.

Whether it is gas purification or high temperature purification, both need containers for graphite powder, i.e. graphite crucible or graphite trough, and also need to use graphite vent pipe for gas purification process.


Product Advantages

Raw material selection.

Graphite crucible: There are two kinds of graphite crucibles for negative electrode material purification, i.e. pure graphite crucible processed and formed, and regenerated graphite crucible pressed and formed, while pure graphite crucible is generally processed with high power electrode material, and regenerated graphite crucible is made of high quality graphite powder as raw material, after batching, forming and sintering.

Slot: In order to reduce the production cost and improve the product cost performance, the raw material is usually carbon anode for aluminum, which is sawed into square strips and plates and masoned according to the size of the slot.

Ventilation tube: Ventilation tube is also divided into pure graphite ventilator and recycled graphite ventilator, whose material and production process are the same as graphite crucible.

Feedback: Many years of practical production and application have proved that our above products are reliable, high quality and low price, long service life and high cost performance.
