Saideli Juncai Liu: intelligent transformation and upgrading of production equipment

The price of raw materials in the upstream is high, and the downstream mainframe factory transmits subsidies to the slope pressure. Under the multi-layer extrusion, “reducing costs and increasing efficiency” has become an unavoidable topic in all aspects of the lithium battery industry chain.

So how should the cost reduction of 811 ternary precursors and ternary materials be unfolded? The current high-tech lithium battery industry summit gave the idea.

On May 21st, the 11th High-tech Lithium-Ion Industry Summit was held at the Four Seasons Hotel in Shenzhen with the theme of “Industry Change, Competition and Risk Avoidance, Enterprise Stratification and Stability”. As the authoritative platform for the lithium battery industry, this summit attracted more than 700 senior executives from the entire new energy vehicle industry chain including materials, equipment, batteries, BMS, PACK and vehicles.

At the meeting, Juncai Liu, the chairman of Saideli, delivered a keynote speech on “Application of 811 Three-Dimensional Precursor and ternary Materials Complete Automation Equipment”.

Juncai Liu believes that the current domestic lithium battery cathode material production equipment has the disadvantages of process dispersion, operation dispersion, control dispersion, dust pollution and labor intensity. Through intelligent upgrade, the choice of closed operation and intelligent monitoring is to overcome the above problems. It is one of the important directions to assist cathode materials companies to reduce costs and promote the improvement of cathode material production equipment.

Previously, through the intelligent transformation and upgrading of production equipment, Saideli has built a 30,000-yuan ternary material automation production line for lithium battery cathode materials customers in Huizhou. The actual use shows that the new production line only needs 10 operations. Workers can achieve the production effect that the original 500 people can achieve.

Specifically, the ternary precursor production equipment provided by Saideli can realize the whole process automation of “automatic batching-reaction-aging-washing-neutralization-re-washing-drying-screening-batch mixing”, the process involves ammonia water. Dust removal, caustic soda fuel dedusting, multi-component dispensing tanks, iron removal, filtration and other complete processes, and the core of the equipment is "reaction".

In the actual production process, the materials after the ingredients are finished, through the reaction process, full material agitation under nitrogen conditions. In this process, all temperature control, pH value, including various salts and alkalis are automatically controlled, and the reaction is carried out. After the completion, the device will automatically enter the aging, so that the product capacity and crystal shape remain in good condition.

Finished materials in a fully enclosed environment, after washing and neutralization, will be centrifuged under the action of a fully automatic centrifuge, and after the subsequent neutralization, the alkaline substances will be washed, and the subsequent materials will be conveyed, dried, and mixed in batches. The iron-removal packaging will also be controlled by computer to achieve fully automated production, ensuring production accuracy and avoiding waste of resources.

Similarly, on the 811 cathode material complete equipment, Saideli also carried out a large number of research and development investment, successfully developed without contact with air, can achieve automatic batching, high-speed mixing, low-speed calcination, crushing, washing, dry coating, secondary calcination, crushing batch mixing, iron removal packaging and other complete automation equipment.

Overall, Saideli's automated production line for cathode materials has the following five advantages:

1. Adopt intelligent manufacturing technology to reduce labor intensity and reduce production costs.

2. The whole process of material transfer, transshipment and production is carried out under closed conditions, which avoids dust pollution to the environment, improves the working environment and reduces the probability of occupational diseases.

3. The dry iron removal process and the dry iron removal process are used to reduce the magnetic content of the product and improve the performance of the product.

4. The use of multi-batch mixing technology to ensure product performance consistency.

5. Adopting the central control intelligent manufacturing system to comprehensively monitor the production process, effectively prevent the occurrence of quality accidents and safety accidents, and avoid the uncertainty caused by human operation and improving product performance and product batch stability.

Founded in 1997, Saideli is a publicly traded company specializing in intelligent equipment. The stock code is 430097. The company's customers include the lithium battery industry, the coatings industry and the bio-industry.
