Description

Technical Field

[0001] The utility model relates to the technical field of electrolyte production, in particular to a reactive distillation device for producing electrolyte additives. Background Art

[0002] A lithium-ion battery is a rechargeable battery that mainly works by moving between a positive electrode and a negative electrode. During the charging and discharging process, Li+ shuttles back and forth between the two: during charging, Li+ deintercalates from the positive electrode and intercalates into the negative electrode, and the negative electrode is in a lithium-rich state; during discharging, it is the opposite. When producing lithium batteries, electrolytes are required, and additives are often added to the electrolytes.

[0003] After the rectification device heats the raw materials, the generated steam of the raw materials drifts upward. When the steam contacts the upper inner wall of the box body, partial condensation is likely to occur. At this time, this part of the raw materials will adhere to the upper side wall of the tray, which is likely to cause the adhered raw materials to be unable to be recovered, resulting in waste of raw materials.
