The curing reaction study of the active material in the lead-acid battery

A study of the curing reaction involved in the positive plate of the lead-acid battery has been undertaken. The variation of the different parameters of the curing reaction has shown the possibility of changing the 4BS needles dimensions. In particular, the addition of a surfactant agent, namely the polyvinylpyrrolidone, to the reagents allows the obtention of tailor-made 4BS particles useable in the industrial preparation of the positive plates.
