Abstraet: When the 4BS seeds as an additive with the content of 1 % were added into the anode materials, the reaction of fine and uniform 4BS particles generated in the plates was triggered, which could improve the consistency of the plate performance to a large extent. By combining with 75 C high temperature curing process, the content of 4BS in the green plates could be increased to 75 %, and the oxidation efficiency of free lead was higher. By introducing 4BS seeds, the porosity of lead paste could be increased up to 46.6 %, which was good for oxygen to get into the lead paste, then making the curing easier and the active materials of the plate more cohesive. By optimizing the process, 4BS seeds could improve the content of α-PbO, in the red plates and crystallize the active materials. The experiment showed that the introduction of 4BS seeds could shorten the production time, improve the formation efficiency and consistency of the plates, and finally extend the life of the battery.
