Soc. 154 A481 An overview of the manufacturing processes and performance requirements of nonwoven separators used in primary and secondary alkaline battery systems is presented. The systems described are alkaline manganese (Alk-Mn), nickel-cadmium , nickel-metal-hydride , nickel-zinc , and zinc-air batteries.
The technologies of web formation, which are relevant for alkaline battery separators, are dry-laid process, wet-laid process, spun-bond process, and melt-blown process. Each of these technologies is used to a greater or lesser extent in the production of battery separators.
While a number of review articles dealing with separators used in lead acid and lithium batteries have been published within the last few years, 1 – 4 there have been no papers covering separators exclusively for alkaline systems. The aim of the present paper is to fill this gap.
Battery separators produced by this technology, and especially those using bicomponent fibers, possess excellent mechanical strength. The nonwoven structure is maintained during the bonding process, and no additional chemistry is introduced to the battery system.
To build manganese dioxide batteries as plate cells good conductive screens would be needed. A well known example for a bipolar Mn02-Zn cell in commercial production is the 6 Volt Polaroid camera film battery, a primary battery with a weakly acidic electrolyte.
Post-treatment is normally done in a separate step. Additional treatments like thickness adjustment might also be done in-line, or in a separate step. The technologies of web formation, which are relevant for alkaline battery separators, are dry-laid process, wet-laid process, spun-bond process, and melt-blown process.
