Problems solved by technology

There are many problems in the above process. On the one hand, the formation time is too long, which greatly prolongs the production cycle of the lead-acid battery. On the other hand, the power consumption is large, which increases the production cost of the lead-acid battery. The key point is that due to long-term charging and discharging, the overall heat generation is serious during the internal formation process, which will affect the normal service life of the lead-acid battery
In addition, in the process of formation, a large amount of acid mist will be produced, causing environmental pollution

Abstract

The invention discloses a container formation process for a lead-acid battery. The process generally comprises the following steps: 1, adaptation and activation in an early stage; 2, continuous and steady container formation; 3, discharging and buffering; 4, deep container formation; 5, electrolyte supplementing; and 6, adjustment on the consistency of the electrolyte in the battery. By utilizing the process, the time for container formation can be effectively saved; meanwhile, because the design of the process completely meets the reaction rule of a counter electrode and the electrolyte, the process has the advantages of short formation time, less power consumption and the like; and the lead-acid battery subjected to formation has the advantage of longer service life.

Description

technical field [0001] The invention relates to an environment-friendly, energy-saving and high-efficiency lead-acid battery internal formation process. Background technique [0002] In the follow-up process of lead-acid battery processing, the battery needs to be internalized to activate the battery plate. The existing internalization process generally involves charging the battery, then discharging, followed by secondary charging, and finally completing the secondary discharge. , taking a 12V100Ah lead-acid battery as an example, the above-mentioned internalization process takes more than 70 hours. There are many problems in the above process. On the one hand, the formation time is too long, which greatly prolongs the production cycle of the lead-acid battery. On the other hand, the power consumption is large, which increases the production cost of the lead-acid battery. The key point is that due to long-term charging and discharging, the overall heat generation is seriou...
