After more than ten years of development and improvement, China’s lithium battery industry is now the world’s largest lithium battery materials and battery production base, and in the entire battery process production line, the value of the coating process is undoubtedly the largest, it can be said that the most important, everyone says that the battery is done well, but also depends on the coating effect.

IS200ERSMG2A In the coating process, the main function of the feed system is to accurately feed the homogenized stock to the coating roller, and maintain the stability and uniformity of the feed. Here, the screw pump is used as the power device of the slurry supply, and the accuracy and uniformity of the slurry supply is crucial, which will affect the subsequent coating process, and then lead to the defects of the coating product.

With the improvement of consumers’ requirements for the capacity and consistency of lithium batteries, the manufacturing process of lithium batteries is also being improved accordingly. In order to avoid product defects caused by imprecise and uneven slurry control, improve product qualification rate and quality stability, in the feeding link of the coating section, the flow meter can be added to control the screw pump to accurately and stably transport slurry and monitor the uniformity of slurry in real time. In addition, with the improvement of the safety and reliability requirements of customers in the production process of lithium battery, it is necessary to trace the production of each battery, which requires historical records of data to achieve the restoration of each production link.

IS200ERSMG2A

A domestic lithium battery industry leader in the coating machine upgrade by adding Emerson Micro Motion™ (High precision ™) ELITE series sensor to improve the accuracy of flow monitoring to meet the customer’s minimum measurement flow of 0.3kg/min. The accuracy of the flow meter can reach 0.1% (which can be further improved to 0.05%), and with the high precision 1600 transmitter, it can achieve:

1, density output to monitor the uniformity of the slurry to avoid product defects caused by uneven layering of the slurry.

IS200ERSMG2A 2, measurement data history record and traceability, storage function supports fast record 1 second each time, including data and abnormal events, can be recorded continuously for 7 days, slow record 5 minutes each time, can be recorded continuously for 30 days, two records work at the same time. The traceability and audit of the coating data are realized to achieve the accuracy, reliability and traceability of the coating process and ensure the consistency of the pole sheet.

3, Ethernet communication, support Ethernet/IP and Modbus TCP protocol, easy to maintain, digital signals no longer have electromagnetic interference, signal attenuation caused by traffic fluctuations and drift. Configuration communication can also be selected to support mah, frequency or discrete output.

4, advanced PoE Ethernet power supply technology, through a cable can achieve power supply and data transmission, reduce wiring complexity, reduce wiring costs.

5, built-in Webserver and USB-C jack, easy system monitoring and configuration.

6, compact design, save site space, easy to achieve integrated installation.

For lithium battery manufacturers to upgrade their manufacturing processes due to today’s increasing consumer demand, Emerson ELITE Series sensors with 1600 transmitters help you achieve high flow monitoring accuracy, density monitoring, reliability and traceability to improve product compliance and quality stability.
