Lithium battery is mainly composed of positive electrode material, negative electrode material, separator and electrolyte, etc. The positive electrode material is an important part of lithium battery, and the cost accounts for about 50% of the whole battery. Lithium battery cathode material production line, from raw material sending, feeding, batching, mixing, sintering (including secondary or tertiary sintering) to final packaging, each link is connected by pipelines to form a closed conveying system. Pipes are conveying pipes made of PC pipes, glass fiber reinforced plastics and other materials, and the amount of pipes is large.
In the past three years, the rapid development of the domestic new energy vehicle industry has put forward higher requirements for the safety performance and energy density of battery materials, and high nickel ternary has become the mainstream. Compared with traditional cathode materials such as lithium iron phosphate, high-nickel ternary materials have higher hardness, higher requirements for wear resistance of pipelines, and stricter demagnetization (no copper, iron, and zinc).
The integral wear-resistant ceramic pipe has smooth inner and outer walls, smooth air flow, extremely low wear and good pressure resistance, and has the characteristics of super wear resistance, corrosion resistance and high temperature resistance. The non-metal lining material can effectively block the contact between the powder and harmful substances such as iron, reduce the content of impurities such as iron in the positive electrode material, and improve the safety performance of the battery.
