Document Type and Number:
WIPO Patent Application WO/2018/062106
Kind Code:
A1
Abstract:
[Problem] In prior art, in order to give excellent electrolyte-holding abilities, acid resistance, oxidation resistance, and the like, to a separator, various studies have been carried out, as in subjecting a fiber to hydrophilization, or combining different types of fibers. However, these methods have the problem of involving dangerous processes and high costs, and the problem of not yielding separators that are satisfactory in terms of battery performance, due to a rise in the separator resistance value. The objective of the present invention is to provide an acrylonitrillic fiber for a separator, a separator containing the fiber, and a lead-acid battery containing the separator requiring no dangerous processes during production, having an excellent electrolyte-holding capacity, and capable of suppressing a rise in the separator resistance value.
[Solution] This acrylonitrillic fiber for a separator has a volume resistivity value of 1 × 109 Ω·cm or lower, and contains a hydrophilic component within the fiber.
