Our company has accumulated perfect solutions for iron ion isolation and wear-resistant reduction of impurities in cathode materials and battery production equipment, and has greatly improved its self-discharge performance after processing cathode materials into finished batteries.

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, The iron content of stainless steel is up to 70%, which causes serious pollution to the battery powder. In the past, the equipment generally uses teflon coating, which has short life and poor high temperature resistance, and needs regular maintenance. But our company uses wear-resistant tungsten carbide coating to solve such problems.
Our company adopts integral tungsten carbide spraying treatment for the high-speed mixer, the whole machine, accessories (blade, tank, outlet) and the contact part of the material in the cathode material production equipment.
In order to solve the problem of introducing the element impurities such as sodium borosilicate in the positive electrode materials of FRP coating, the whole spraying treatment is carried out for the double-cone spiral mixer (spiral, tank).
After the treatment of the stirring paddle of the battery slurry mixing equipment, the introduction of impurities in the stainless steel wear agent is reduced, and the battery self-discharge ratio is greatly reduced.
