SureCure® is added to a battery’s positive active material where it acts as “seed crystals” to promote uniform tetrabasic lead sulfate (TTBLS) crystal growth during paste mixing and plate curing. This results in multiple benefits.
AFTER
BEFORESmall crystals of Tetrabasic Lead Sulfate (TTBLS) are very effective in accelerating the conversion of Tribasic Lead Sulfate to Tetrabasic Lead Sulfate during paste mixing and curing.
With Hammond’s advanced global manufacturing capabilities, SureCure® can be engineered to meet our customers’ specific particle and batch size needs. And with our robust production management system, we ensure consistent, trackable results.
There are two cost savings opportunities with SureCure®. The most significant cost savings is “up to a 5% reduction in positive active material with the addition of SureCure® as the positive paste density can be reduced since a tetrabasic lead sulfate cured plate is much stronger than a tribasic lead sulfate cured plate.
In each of several full-scale trials at automotive and industrial battery manufacturers, the simple replacement of 1% by weight of battery oxide with SureCure® is shown to accelerate significantly the conversion of tribasic lead sulfate (3BS) to tetrabasic lead sulfate (4BS) in the curing process while improving crystal structure and reproducibility. Shorter curing times result in reduced labor and energy costs, as well as reduced fixed (curing chambers and plant footprint), and working (plate inventory) capital investment.
Hammond’s research team has developed the next generation of SureCure® products that provide improved formation efficiency and longer cycle-life.
