Description
Technical Field
The invention belongs to the technical field of storage battery formation, and particularly relates to a storage battery vacuum formation system and a formation process.
Background
The formation process of the lead-acid storage battery mainly comprises an electrode plate external formation process and a battery internal formation process. The battery internal formation process is divided into a common internal formation process and an acid circulation internal formation process. In order to adapt to the situation that the environmental protection requirement is stricter, most battery manufacturing enterprises adopt an internal formation process at present.
As a common internal formation process, in the formation process, the electrolyte inside the battery does not circularly flow with the outside of the battery, and the battery is generally cooled by water bath or air cooling. In the common internal formation process, because the space inside the battery is limited, the amount of electrolyte is relatively small, the heat capacity of the battery is low, and the temperature of the battery is not easy to control. In order to control the charging temperature of the battery, the charging current must be reduced, so that the formation charging time is prolonged, and the formation efficiency is very low. In addition, by adopting a common internal formation process, the consistency of the battery is poor due to the fact that the density difference of electrolyte among the batteries is large under the influence of artificial control factors.
As an acid circulation internal formation process, in the formation process, electrolyte inside the battery circularly flows with the outside, and heat dissipation and temperature reduction are realized through the circular flow of the electrolyte. The acid circulation internal formation process can shorten the formation time by increasing the current density through carrying out low-density acid circulation pickling, low-density acid circulation multi-stage charging and discharging formation, high-density acid circulation acid exchange, automatic control of the formation temperature of the battery, automatic control of the density of the circulating acid liquor and the like on the battery, thereby improving the formation efficiency of the battery. In addition, the acid circulation container formation process simplifies the operation and reduces the labor intensity.
Compared with the common internal formation process, the acid circulation internal formation process has incomparable advantages, but also has the following limitations: the existing acid circulation process is only suitable for internalization of the rich-solution lead-acid storage battery, and the AGM clapboard VRLA valve-controlled sealed lead-acid battery is not suitable for the internalization process of the acid circulation because the assembly pressure of a pole group is high, the pole group is in a tight assembly state, the fluidity of electrolyte in the battery is poor, and the flowing, heat dissipation and cooling of the electrolyte in the battery are influenced; and secondly, the problem of electric leakage and bias current exists in the acid circulation internal formation, in the same formation charging loop, the current of the middle battery is lower than that of the batteries close to the positive and negative terminals at the two ends of the loop (the difference between the serial charging currents of 10 batteries is about 10 percent), and the bias current problem among different batteries becomes more serious along with the increase of the number of the batteries in series in each loop, so that the difference of the formation effect of the batteries is objectively caused, and the consistency among the batteries is influenced.
In summary, the container formation process of lead-acid batteries still has a great space for improvement, and needs continuous efforts and continuous improvements of lead-acid battery technicians.
