In recent years, with the rapid development of the new energy industry, lithium batteries are its core component, and its upstream and downstream industries have also shown rapid growth. Lithium battery cathode material powder transportation is a key link in the lithium battery manufacturing process and plays a vital role in ensuring production efficiency and product quality. To ensure the stability, efficiency, and safety of cathode materials during transportation, the design and material selection of transportation pipelines need to meet a series of requirements.
Lithium battery cathode material transportation pipeline requirements
Isolate metal: The cathode material of lithium battery will directly affect the performance of lithium battery and is very sensitive to metal pollution. Therefore, metal needs to be isolated during transportation. This requires us not to use metal pipes. We can use ceramics, glass, polymers, and other materials. pipeline.
Wear resistance: The cathode material transports a large amount, and the pipeline is in a high-load operation state for a long time and will be subject to continuous wear. Once the wear resistance of the pipeline is poor, it will be worn and worn out in a short period, causing material leakage, pollution, etc. It requires shutdown for maintenance, which is time-consuming, laborious, and cost-intensive. Therefore, pipeline wear resistance is also an important requirement for lithium battery cathode material transportation pipelines.
Good sealing: The positive electrode material transportation process requires good sealing to avoid powder leakage and contamination.
How to select materials for lithium battery cathode material transportation pipelines?
The requirement to isolate metal first excludes metal pipes, and good wear resistance also limits the use of glass pipes and polymer pipes. Ordinary glass pipes are too fragile, inconvenient to transport and install, and are prone to breakage, cracking, and other problems. To improve the wear resistance and strength of glass pipes, the cost will increase sharply, which is not in line with actual needs.
The same is true for polymer materials. The wear resistance of ordinary polymer materials cannot meet the requirements, and the ones that meet the requirements are too expensive. Both materials have appeared in lithium battery cathode material transportation pipelines but were quickly replaced by ceramic tubes due to their limitations.
The ceramic tube not only isolates metal and eliminates metal pollution, but also has high hardness and is super wear-resistant. The integrally formed wear-resistant ceramic tube greatly reduces splicing gaps, has good sealing performance, and has a smooth inner wall, which reduces hanging materials and blocking materials. Feedback since it was put into the market is good!
