Graphite sagger/crucible/box play an important role in the production of lithium-ion batteries. The main purpose is to carry and fix the negative electrode material, ensuring the sintering in the manufacturing process of lithium batteries goes smoothly. It has excellent properties such as high strength, high purity, high temperature resistance, corrosion resistance, and wear resistance to ensure the manufacturing quality and stability of lithium batteries.
