Application of nonwovens in batteries
- Freudenberg Nonwovens, Weinheim (Germany)
Nonwovens are textile products that are manufactured directly from fibers. According to ISO 9092: 1988 nonwovens are defined as a manufactured sheet, web or batt of directionally or randomly oriented fibers, bonded by friction, and/or cohesion, and/or adhesion excluding paper and products which are woven, tufted, stitchbonded incorporating binding yarns or filaments, or felted by wetmilling whether or not additionally needled. The fibers may be of natural or man-made origin. They may be staple or continuous filaments or be formed in situ. The production of nonwovens can be described as taking place in three stages, although modern technology allows an overlapping of the stages. The three stages are: web formation, web bonding, and finishing treatments. The opportunity to combine different raw materials and different techniques accounts for the diversity of the industry and its products. This diversity is enhanced by the ability to engineer nonwovens to have specific properties and to perform specific tasks. This paper describes the production and applications of nonwovens in primary and secondary electric batteries.
