Advantages of LONGLY Production Line for Cathode Material Lithium Iron Phosphate(LFP)

The battery cathode materials, commonly Lithium iron phosphate(LFP), Lithium-Ion Manganese Oxide (LMO), and lithium nickel manganese cobalt oxides(NMC), usually account for more than 30% of the cost of the entire battery. In 2024, China's total output of lithium iron phosphate cathode materials was more than 2.3 million tons, an increase of about 84% yearly.

Lithium iron phosphate, an inorganic compound with an olivine structure, goes through grinding, drying, crushing, and other processes as the cathode material in lithium-ion batteries. Compared with other cathode materials, it is outstanding in terms of low cost, high safety, low toxicity, long cycle life, and other factors. Because of relatively rich raw sources and stable structure, it greatly supports the long-term safe use of lithium batteries.

To meet the growing demand for lithium iron phosphate, our cathode automated production line enhances production efficiency while improving quality. This solution addresses challenges related to high reliability, technological advancement, and cost-effectiveness.

▲Scheme of Automated Production Line for Cathode Materials in Li-ion Batteries

First, the automatic production line can realize automated packaging and warehousing, product testing, and production process monitoring. It coordinates each stage orderly and reasonably by equipping with the appropriate production equipment, intelligent production execution management systems, and control programs to maximize product quality and production efficiency.

Compared with other manufacturers, LONGLY has more successful experience in scheming, engineering, construction, operation, and applications on automatic LFP cathode production lines. So taking early warning to avoid any potential issues and addressing the technical obstacles in the production line is accessible.

Secondly, the LONGLY lithium iron phosphate cathode production line adopts the standard of Industry 4.0. All equipment is managed by the central control with every signal collected for data analysis allowing for better decision-making and automatic measures taken. The error prevention and correction functions equipped in our production line allow real-time status monitoring during every stage, and warning and alarm if any error is detected. Such high automated system allows unmanned operation.

Thirdly, the contact parts of our cathode material production line with products are all made of 304 stainless steel or ceramic materials, which effectively prevent impurities from metal pollutants. So, apart from the battery materials, it can be applied to pharmaceutical and food products, which are highly required. The demagnetization and iron removal devices are optional in the production line to minimize metal pollution.

In addition, with the help of our R&D and installation technical team, all core components are independently processed and produced by LONGLY, perfectly matching the production lines for different products from the source. Our automated production line can also be equipped with a complete system covering dust removal, noise reduction, sewage discharge, cleaning, and recycling to ensure that the workshop is clean and tidy and provides a clean and healthy working environment for the staff.

At the same time, the LONGLY production line has a higher degree of automation and the labor cost can be reduced by more than 90% on the original basis. Some stages can achieve completely unmanned operation, which can automatically correct errors. Meanwhile, the transformation is upgraded and the overall energy consumption rate can be reduced by 15-30%.
