Challenges And Responses: The Importance Of Liquid Level Measurement Technology in The Process Of Lithium Battery Cathode Raw Materials

In the new energy vehicle industry, lithium battery cost and performance optimization are crucial to improving product competitiveness. As an indispensable link in the lithium battery production process, Lithium battery raw material level measurement is directly related to product quality and safety control, so it places extremely high requirements on the performance of Cobalt sulfate solution level measurement instruments.

When preparing cobalt tetroxide, the process of adding ammonium bicarbonate solution to the cobalt sulfate solution to generate the precursor precipitate cobalt carbonate is called cobalt precipitation. Next, the precursor is granulated, dried, and calcined, and then a cobalt tetraoxide product with a crystal form of agglomerated polyhedron or octahedron is obtained. In this process, SLDL5285 80GHz high frequency radar level meter was used to measure the liquid level of the cobalt sulfate solution cobalt precipitation reactor to ensure the stability and controllability of the production process.

However, in actual working conditions, Lithium battery raw material level measurement faces many challenges. For example, the tank is in a high-temperature environment and steam and crystallization are generated. The cobalt sulfate solution is corrosive to a certain extent. The tank is equipped with multi-layer stirring paddles and heating coils. In view of these complex working conditions, traditional low-frequency radar and radio frequency admittance and other liquid level gauges cannot meet the requirements of on-site process control. In addition, the presence of crystallized material will interfere with the radar measurement signal, and frequent cleaning of the antenna will cause damage to the level gauge.

In response to these challenges, SOLIDAT launched a solution: they chose the SLDL5285, an 80GHz high frequency radar level meter with a process-sealed antenna for measurement. The level gauge has good penetration of vapors and crystals while being resistant to interference. Thanks to its ultra-small 3° emission angle and suppression of false echoes, the interference problems of multi-layer stirring and heating coils are also effectively solved. Therefore, despite being subjected to various interferences, SLDL5285 can still obtain strong liquid level echo signals, achieving stable and reliable liquid level measurement without frequent maintenance, and is highly recognized by on-site users.

As one of the key products in core basic industries, lithium batteries play important applications in various fields. SOLIDAT has a variety of level products that can easily cope with various challenges in measurement tasks in the lithium battery industry and achieve safe and effective operation of the production process. Through the application of SLDL5285 80GHz high frequency radar level meter, the liquid level measurement problem in the lithium battery production process has been effectively solved, providing strong support for the development of the entire new energy automobile industry.
