The curing of positive plates for lead–acid batteries is a critical operation. During this process, the chemical and physical structure of the active-material is established and the plates develop the strength that is required for subsequent mechanical handling. (1. Introduction)
The optimum curing temperature has been found experimentally as 350°F (177°C), which corresponds to a steam pressure of 8 kg/cm 2 above atmospheric pressure. The high pressure steam curing has been found most effective when finely ground silica is added to the cement.
When the temperature is increased and an appropriate humidity cyclogram is chosen, the curing processes are enhanced which allows the duration of the curing process to be reduced from 72 to 48h. However, temperature rise is limited to 65°C because above this temperature, a transformation reaction of to begins.
The additive promotes rapid conversion of 3BS to 4BS in the curing chamber at temperatures above 55 °C (130 °F) when low paste-mixing temperatures result in reduced 4BS formation in the paste mix. This reduces the need to develop this material during the curing process by causing formation of 4BS in the paste mix.
SureCure ® (median particle size = 0.8 μm) increases battery life, particularly in cycling applications. As noted above, the principal reason for producing batteries with 4BS in the positive plates is this increase in life.
