David P. Boden and Benjamin Labovitz of Hammond Lead Products explain how the addition of just a little leady oxide and tetrabasic lead sulfate can save so much time in curing.
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 required for subsequent mechanical handling. When a paste mix is prepared by conventional methods, the primary compounds present are tribasic lead sulfate (TRBLS), unreacted lead oxide (PbO) and free lead. It has become apparent . . .
