Our company in the cathode material and battery production equipment iron ion isolation and wear reduction of impurities into the accumulation of perfect solutions, and the cathode material processing into finished battery greatly improved its self-discharge performance.

Battery material production process, there shall be no contact with the iron component, a lot of conical cylinder and conical spiral mixer, two of the mixing screw is made of stainless steel body, but the powder in the process of mixing with batteries, constantly friction cylinder, working long hours, barrel and screw blade will appear a lot of wear and wear down the stainless steel impurities mixed in battery powder, Iron content in stainless steel is up to 70%, which causes serious pollution to battery powder. In the past, Teflon coating was generally used for equipment, which needed regular maintenance due to its short life and poor high temperature resistance. However, our company used wear-resistant tungsten carbide coating to solve such problems.

Our company adopts integral tungsten carbide spray treatment for the contact parts of high speed mixer, complete machine, accessories (blade, tank, discharge port) and materials in the cathode material production equipment.
For the double cone screw mixer (screw, tank) overall spraying treatment to solve the previous FRP coating into the cathode material of sodium borosilicate and other element impurities.
After the treatment of the stirring paddle of the battery mixing equipment, the impurity introduction of the stainless steel wear agent was reduced, and the self-discharge ratio of the battery was greatly reduced.
