What are the precautions for processing lithium battery electrolyte

Precautions for lithium battery electrolyte processing 1. The polishing solution foams during electrolytic polishing at the beginning of its use, so the distance between the polishing solution surface and the top of the polishing tank should not be ≤ 15cm. 2. Before the stainless steel workpiece enters the polishing tank, the moisture remaining on the surface of the workpiece should be removed as much as possible. Excessive moisture on the workpiece may cause serious pitting on the polished surface, and local erosion will cause the workpiece to be scrapped. 3. In the electrolytic polishing process, the iron and chromium elements contained in the stainless steel workpiece as the anode are continuously transformed into metal ions and dissolved in the polishing solution without depositing on the surface of the cathode. As the polishing process progresses, the concentration of metal ions continues to increase. When a certain value is reached, these metal ions continuously precipitate out of the polishing solution in the form of phosphate and sulfate, and settle at the bottom of the polishing tank. For this reason, the polishing liquid must be filtered regularly to remove these solid deposits. 4. During the operation of the polishing tank, in addition to the continuous consumption of phosphoric acid and sulfuric acid, water is lost due to evaporation and electrolysis. In addition, the high-viscosity polishing fluid is continuously entrained and lost by the workpiece, and the polishing fluid level continues to drop, so it is necessary to frequently add to the polishing tank.
