Development of VRLA batteries for high rate discharge applications

摘要

During high-rate discharge, there is less utilization of the sealed, valve-regulated lead/acid VRSLA batteries because the secondary current distribution is less uniform and there is less time for ion diffusion. This study investigated the effects of positive plates' material porosity positive egative active material ratio, and electrode stacking pressure on cell performance during high-rate discharge. According to the experimental results, the cells with a porosity of 74-76/100 and positiveegative active material ratio of 1.2-1.5 Exhibited the best cell performance.
