AI Technical Summary
Existing technologies for preparing lithium-ion battery cathode material precursors suffer from problems such as uneven mixing of metal salts, sampling contamination, and lag in detection and fine-tuning, leading to deviations in the proportion of main elements and making them unsuitable for industrial continuous production.
A dynamic adjustment multi-component precursor preparation device is adopted, which forms an in-tank circulation mixing through a variable frequency centrifugal pump. Combined with online detection by a potentiometric titrator and automatic sampling by a precision flow meter, a closed-loop control system is constructed to achieve uniform mixing and precise adjustment of the metal salt solution.
It achieves uniform mixing of molten metal and accurate detection results, reduces ratio deviation and material scrap, is suitable for the preparation of multi-component precursors, meets the needs of industrial production, and reduces production costs.
