Zirconium Oxide Fibers for Cell Separators of Alkaline Storage Batteries

Resumo

A porous composite material based on zirconium oxide fiber that possesses satisfactory mechanical strength and high resistance to attack by concentrated alkali solutions and was obtained. Samples with distinctive pore sizes in layers performing different functions were fabricated. An investigation of the obtained samples showed that zirconium oxide fibers with high temperature tolerance and chemical resistance, especially with respect to attack by alkali, show good promise for fabricating the cell separators of alkaline storage batteries, especially in cases where high energy characteristics must be combined with high reliability and long life.
