Background
The internal formation process is also called cadmium-free internal formation process, and is characterized in that battery plates after being solidified and dried are cut and directly assembled into a battery, and the battery is subjected to internal formation charging to obtain a finished product. The internal formation process cancels four working procedures of energy consumption and main wastewater generation, namely polar plate grooving formation, polar plate washing, secondary drying and battery replenishing and charging in the traditional cadmium-containing external formation processing production mode, and compared with the traditional external formation process, the cadmium-free internal formation process reduces water consumption by 90%, saves electricity by 25.8%, reduces cost by 15% and reduces occupational disease hazards of staff by 90%. In addition, the internal formation technology successfully eliminates toxic raw materials of cadmium and arsenic in the traditional process formula, and solves the technical problem of harmless formula in the production of the storage battery by using a new formula of the lead-calcium alloy. After the novel formula of the lead-calcium alloy is applied, the product quality of the battery is superior to that of the traditional process formula.
In the current internal formation charging process, charging is usually required for 70-90 h, the charging time is long, the charging efficiency is not high, and the cost is increased.
