but lead sulfate is more soluble than lead carbonate, which is in turn more soluble than lead phosphate.
As a battery ages through use or through sitting unused for a long period of time, lead sulfate crystals enlarge and can build up excessively to the point that they create a physical barrier across the surface of the plate.
We have produced the specialty battery additive tetrabasic lead sulfate (TTBLS) under our SureCure trade name for years, and new production at ALSB will allow Asian customers to acquire the specialty additive at considerably lower cost than from U.

More chromate ions dissolve out of the core, resulting in core-shell structures with a lead sulfate core and a chromium oxide shell.
Once the battery begins charging again, the lead sulfate dissolves back into solution.
Most of the dead batteries are unusable because the battery plates collect a lead sulfate buildup that prevents the battery from accepting a charge.
Therm-Chek RC 376P and Therm-Chek RC 377P are calcium-zinc powder stabilizers designed to replace tribasic lead sulfate on a part-for-part basis in general-purpose wire and cable-jacketing applications.
This experiment was conducted to test the ability of a commercial circuit to remove lead sulfate from a heavily sulfated lead-acid battery.

As a battery ages through use or sits unused for periods of time, lead sulfate crystals can enlarge and build-up excessively to the point where they create a physical barrier across the surface of the battery plates.
