Description

Technical Field

[0001] The utility model relates to the technical field of electrolyte storage, in particular to a lithium battery electrolyte defoaming storage and transportation system. Background Art

[0002] Lithium-ion batteries, the "heart" of mobile electronics and electric vehicles, play a vital role in driving humanity away from fossil fuels. The electrolyte, one of the four key materials in lithium-ion batteries (positive electrode, negative electrode, separator, and electrolyte), is often called the "blood" of lithium-ion batteries. As the carrier of ions in lithium-ion batteries, it conducts ions between the positive and negative electrodes, playing a decisive role in the battery's ultimate performance.

[0003] During storage and transportation, electrolytes are typically stored in a high-pressure inert gas environment. During this process, a certain amount of gas dissolves, which is often difficult to remove. The presence of bubbles in the electrolyte can affect battery capacity and prevent the required amount from being met. When the electrolyte is in contact with air for extended periods, free water in the air dissolves into the electrolyte. Lithium hexafluorophosphate (LiPF6) undergoes hydrolysis upon contact with water, with hydrofluoric acid (HF) as the primary product. This can corrode the battery electrodes. HF also has a low boiling point, which can easily cause battery bulging, severely impacting battery performance. Therefore, electrolytes must be strictly prohibited from contacting air during production and use. When a production line is shut down for an extended period or when the electrolyte is being changed, the storage tanks require thorough cleaning. Since both the electrolyte and the cleaning agent are toxic, manual handling should be avoided as much as possible during the tank cleaning process.

[0004] Currently, companies in the lithium battery industry typically use simple vacuuming to remove bubbles, or a method combining stirring and vacuuming, which can result in incomplete removal. Electrolyte is typically sealed with nitrogen during storage and transportation to isolate it from air, but nitrogen sealing throughout the entire production process is not well implemented. Cleaning tanks on the sidelines of the workshop often involves simple immersion or manual cleaning, which poses significant risks to tank cleanliness and personal safety.

[0005] Based on the above technical problems, technical personnel in this field urgently need to develop a lithium battery electrolyte defoaming storage and transportation system that can ensure that the electrolyte is in an inert gas protection environment throughout the entire production process and can ensure the cleanliness of the tank and the safety of operators.
