Abstract
A battery paste additive, and process for making the same comprising micronized seed crystals of tetra basic lead sulfate, is added to battery paste and results in accelerated curing time and other improvements in battery performance. The battery paste additive may be used to produce positive or negative battery plates and may be use with conventional mixing, pasting and curing processes and equipment.
Claims35
A method of producing an additive for a battery plate paste, comprising the steps of:
- mixing together water and lead oxide;
- mixing sulfuric acid into the water and lead oxide mixture;
- and
- reacting the mixture of water, lead oxide and sulfuric acid in the presence of a seed amount of tetra basic lead sulfate to create TTBLS crystals.
A method of producing an additive for a battery plate paste, comprising the steps of:
- mixing together water and a lead oxide complexing agent to create a first substance;
- mixing together the first substance with a tetra basic lead sulfate complexing agent to create a second substance;
- mixing together the second substance with a sulfuric acid complexing agent to create TTBLS crystals.
A method of producing a battery paste, said method comprising the steps of:
- mixing together a lead oxide complexing agent and a tetra basic lead sulfate complexing agent to create a first substance;
- mixing together water and a sulfuric acid complexing agent to create a second substance;
- mixing together the first substance with the second substance to create TTBLS crystals;
- micromilling the TTBLS crystals to create a battery paste additive;
- mixing together the battery paste additive with a battery paste mix.

A method of making a battery paste additive comprising the step of reacting a mixture of:
- water;
- lead oxide;
- and
- sulfuric acid;
- in the presence of a seed amount of tetra basic lead sulfate.
A method for making a battery plate, comprising the steps of:
- mixing micronized tetra basic lead sulfate with a battery paste mix to create battery paste, wherein the tetra basic lead sulfate is produced by reacting a mixture of:
- lead oxide;
- sulfuric acid;
- and
- water;
- in the presence of a seed amount of tetra basic lead sulfate;
- and
- curing the battery paste.
