RBSM structure and its effects on fluid and gas transport [in VRLA batteries]

Abstract

This paper discusses the important properties of wicking and wetting of recombinant battery separator media (RBSM) separators for valve-regulated Pb-acid (VRLA) batteries. The absorptive characteristic of a separator is one of the critical parameters required of separators. The ability of a separator to absorb, hold and release electrolyte has a direct influence on battery performance. The fibrous nature of the separator allows for various different design parameters. This paper discusses some of these design criteria.
