A Novel Approach to Developing an Expander with High-Temperature Stability
Lead Acid Batteries operating in hotter regions (such as South Asia, India and South America) have a shorter life than those in cooler regions. Improving the performance of lead acid battery at high ambient temperature has been a hot topic of research and development for lead acid industry. Researchers at Hammond proposed a novel approach to developing new expander with high temperature stability. The Taguchi DOE technique was used to study the performance of several factors under different conditions. Those factors included types of lingosulfonate, carbon black, BaSO4 and dopants (cellulose base materials). These results provide directions for developing novel high temperature expander formulations.
