Synergistic effects of novel battery manufacturing processes for lead acid batteries. Part I: Charge/discharge cycling of batteries

摘要

The present research aimed to ascertain if the merging of novel battery manufacturing processes could achieve an enhancement in the improvement of battery cycle-life. We found that the melding of novel battery manufacturing processes leads to synergistic effects with regard to the cycling performance of lead acid batteries. The novel battery manufacturing processes employed in this study include: (i) grid cleaning; (ii) positive active material compression; and (iii) conductive additives in the positive paste. It was found that combination of positive active material compression and grid cleaning approximately doubles the durability of batteries and is consistent with the additive effects of the individual treatments, while combination of positive active material compression and conductive additives yields an approximate 30% boost in performance compared to the additive effects of the isolated treatments. Synergistic effects were not noted for other combinations of the aforementioned battery manufacturing practices. [References: 30]
