Background

During the production and manufacturing process of the storage battery, acid needs to be added to each unit cell. Because of the small volume and presence of gas in the enclosed cells, direct perfusion is time consuming and difficult to achieve. At present, an automatic vacuumizing acid adding machine is adopted in industrial production, and the acid adding process is accelerated by utilizing negative pressure formed inside a battery after vacuumizing. The quantity of batteries manufactured in laboratory pilot scale is small, and if an automatic acid adding machine is adopted for adding acid, on one hand, the amount of acid required to be prepared is large, and unnecessary waste is caused. On the other hand, the process is more complicated when the acid adding amount is adjusted, and the efficiency is reduced. At present, the battery cells are generally subjected to vacuumizing and acid adding manually by means of a vacuum pump in a laboratory, the workload is large, and the consumed time is long. If the adopted acid adding kettle has a small specification, acid adding needs to be carried out for multiple times, and the efficiency is lower. In addition, when the conventional monomer or conjoined acid pot is used, each single cell needs to be vacuumized one by one, the pressure value of each single cell is difficult to keep consistent, and certain influence is generated on the performance of the battery and the experimental result.
