How effective is the application of wear-resistant ceramic pipes in the lithium battery industry?

2021-11-30
 Latest company case about How effective is the application of wear-resistant ceramic pipes in the lithium battery industry?

Since the birth of lithium electronic battery products in the early 1990s, it has been 30 years. In recent years, with the rapid expansion of my country's 3C market and new energy vehicle market, Chinese companies have risen rapidly and occupy the largest scale in the world. In 2016, China accounted for 15 of the world's TOP 20 lithium battery manufacturers. By 2019, CATL and BYD have ranked among the top in the world in terms of shipments. Around the upstream and downstream of lithium battery manufacturers, a large and complete industrial chain has already been formed in China.

As an important part of the lithium battery, the cost of the cathode material also accounts for about 50% of the overall battery, and its quality is closely related to the quality of the lithium battery. On the lithium battery cathode material production line, from raw material delivery, feeding, batching, mixing, sintering (including secondary or tertiary sintering) to final packaging, each link is connected by pipelines into a closed transportation system, so the amount of pipelines is relatively large. Big. In the early days, PU pipes, rubber pipes and stainless steel pipes were mostly used for conveying pipes.

In the past three years, the rapid development of the domestic new energy automobile industry has put forward higher requirements on the safety performance and energy density of battery materials, and the high nickel ternary has become the mainstream. Compared with traditional cathode materials such as lithium iron phosphate, high-nickel ternary materials have higher hardness and higher requirements on the wear resistance of transportation pipelines. At the same time, they are also more stringent in demagnetization (forbidden copper, iron and zinc). Some manufacturers continue to use FRP liners, PTFE liners, and even tungsten carbide spray tubes that have been used in the lithium iron phosphate preparation system. After use, they find that the service life is extremely short. Some use of FRP straight pipes have leaks in many places within less than six months of the production line, while FRP lined elbow pipes even lasted less than a year on the ferro-phosphorus production line.

 

In fact, the integral wear-resistant ceramic liner has long been widely used in lithium battery production lines in Japan and South Korea. The integral wear-resistant ceramic lined elbow has the characteristics of super wear resistance, corrosion resistance and high temperature resistance. At the same time, as a non-metallic lining material with ultra-high hardness, the ceramic lined elbow can effectively block the contact between powder and iron and other harmful substances, reduce the content of iron and other impurities in the cathode material, and improve the safety performance of the battery.

 

The integral wear-resistant ceramic pipe steel produced by ibeno is integrally formed of 304 stainless steel (integral hot bending, non straight pipe welding), the inner wall is lined with 95 or 99 high-purity alumina ceramic pipe fired at 1700 degrees (most of 90 or 92 porcelain in the market), and the ceramic and steel pipe layer are filled with special adhesive. Different from the general ceramic lined composite pipe, this kind of pipe has smooth inner and outer walls, unobstructed air flow, very low wear, good pressure resistance and corrosion resistance. Practice has proved that, The service life of ibeno wear-resistant ceramic pipeline in high nickel ternary production line is at least five years.
