Abstract
The invention relates to the technical field of a lead storage battery, in particular to a formation method of a fast-charged lead storage battery. The method comprises the following steps that prepared silica gel electrolyte is poured into a battery in a vacuum liquid injection mode; then, the operation is performed according to the steps of constant current charging, constant current discharging and constant current charging; a heat conduction oil pipe is inserted and arranged in the battery; circulating heat conduction oil exists in the heat conduction oil pipe; the formation method at least comprises 13 stages of constant current charging and constant current discharging; the total formation time is 40 to 80h; the constant current charging current is 0.02 to 0.13 C[10]; the constant current discharging current is 0.15 to 0.2 C[10]; the first stage of the formation method comprises at least 6 sub stages of constant current charging; the last stage comprises at least four sub stages of constant current charging. The charging and discharging optimized combination is used; the formation time is greatly shortened; the energy consumption is reduced.
Description
technical field [0001] The invention relates to the technical field of lead-acid batteries, in particular to a formation method for fast-charging lead-acid batteries. Background technique [0002] In view of the proven high performance, low cost, easy recycling and reliable safety of lead-acid batteries, it has been widely used around the world. Formation is an important step in the manufacturing process of lead-acid batteries. The quality of formation directly affects the performance of lead-acid batteries, and the power consumption in the formation process is huge. [0003] During the formation of lead-acid batteries, additives can be added to the formation plates or lead paste. If the additives are used properly, the electrochemical reactions in the formation process can be accelerated, and the formation of the plates is better. In addition to additives, there are also The structure of the plate grid can be improved. There is a grid with a carbon honeycomb structure, whi...
