Zirconia Fiber Separator for Nickel-Hydrogen Battery

Abstract:

Zirconia fiber separator is one of the important materials of nickel-hydrogen battery .In this paper,we studied the factors affecting the properties of zirconia fiber separator used as nickel-hydrogen battery separator, which prepared by precursor process, including the precursor fibers,fibrous cloths,concentration of the precursor solution and the heating rate before 500oC.The results show that, because the gully structure copied the precursor fibers, as well as smaller diameter of the fiber has larger specific surface area, so the zirconia cloth has the higher absorption capacity and retention ability of alkal. In the same way as woven, the low fabric areal density is beneficial to the absorption ability. When the concentration of the precursor solution is 1.36g/ml, the properties of the zirconia fiber separator is the best. If the heating rate is too fast, will cause a decrease in performance of zirconia fiber separator. The diameter of the fibers in the zirconia fiber sepatator is about 4-5μm, the main phase of the separator is tetragonal zirconia.
