SureCure®
SureCure is added to the positive active material paste where it acts as “seed crystals” for the formation of tetrabasic lead sulfate (TTBLS) during paste mixing and curing. Promoting the formation of TTBLS results in a number of benefits including increased battery cycle life, shortened curing time, and a more consistent product.
