Abstract: The lead - acid battery is preferred for energy storage applications due to its operational safety and low cost. However, the cycling performance of the positive electrode is significantly compromised by fast capacity decay caused by the softening and shedding of positive active material (PAM). The curing process imparts a crystalline structure to the active material, acting as a skeleton for the micro - crystalline structures established during formation. This article reports on high - and low - temperature curing algorithms for positive plates used in valve - regulated gel batteries for a 70% depth of discharge (DOD) performance test. The high - temperature - cured plate exhibited a 4BS crystal for cyclic performance, while the low - temperature - cured plate had a 3BS crystal for high initial capacity and cranking applications. Our experimental results show that the higher - temperature curing algorithm yields better 70% DOD performance than the low - temperature curing algorithm.
