Pre-Carbonized Graphite Crucible for Negative Electrode Material Pre-Carbonization

  • Good thermal conductivity, uniform heat dissipation and high strength.
  • Excellent thermal shock resistance and corrosion resistance.
  • Can be used for the pretreatment of anode materials
Many pre-carbonized graphite crucibles are placed outside the workshop.

The pre-carbonized graphite crucible for negative electrode materials is a graphite crucible specially made from artificial graphite material for the pre-treatment of negative electrode materials. The pre-treatment process includes pre-roasting and pre-carbonization, which are very important steps in the preparation of negative electrode materials. Pre-carbonization treatment allows the gases and impurities in the negative electrode material to evaporate and form a uniform carbonized layer, thus improving the electrical conductivity and stability of the negative electrode material.

It should be noted that this crucible can only be used for carbonization treatment and cannot be used for graphitization treatment, as graphitization requires higher temperature.
