Separators used in early lead-acid batteries
This review discusses various interactions between organic compounds, brought into the lead–acid battery via the separator, and their subsequent effect on battery performance. Historically, the interrelationship. The separator is the distance-keeping component between the positive and the negative e. In the early days of lead–acid batteries, wood veneers were widely used as separator material. At that time, no acid-stable synthetics were commercially available, or eve. Modern synthetic lead–acid battery separators, e.g., polyethylene containing silica agglomerates, are reinforced by a network of extremely long macromolecules, shown as strings. All organics are decomposed with time in the hostile environment of a lead–acid cell. The separator should be as stable as possible, at least as long as the expected battery life, whic. Another highly interesting field of interaction between separator organics and lead–acid battery electrochemistry is the so-called antimony poisoning. During the cycling of conventional trac.
