摘要： A separator material of the present invention is a sulfonated nonwoven that comprises a polyolefin ultra-fine short fiber having a fineness of less than 0.5 dtex and other polyolefin short fiber(s). The other polyolefin short fibers include a polyolefin thermal bonding short fiber. At least a portion of the polyolefin thermal bonding short fiber is flattened to bond the component fibers together. The nonwoven has a specific surface area in a range of 0.6 m2/g to 1.5 m2/g and satisfies the following ranges. (1) A ratio (S/C)E of the number of sulfur atoms (S) to the number of carbon atoms (C) in the nonwoven, as measured by Electron Spectroscopy for Chemical Analysis (ESCA), is in a range of 5×10−3 to 60×10−3. (2) A ratio (S/C)B of the number of sulfur atoms (S) to the number of carbon atoms (C) in the nonwoven, as measured by a flask combustion technique, is in a range of 2.5×10−3 to 7×10−3. (3) A ratio (S/C)E/(S/C)B (depth of sulfonation) of (S/C)E to (S/C)B is in a range of 1.5 to 12. Thus, a separator material that has a high level of self-discharging performance when charge and discharge are repeatedly performed, a high level of process performance when assembling a battery, and a high level of short-circuit withstand capability; a method of producing the same; and an alkali secondary battery separator, are provided.

摘要： A battery separator and a method for manufacturing the same and a battery using the same. The battery separator is excellent in alkaline retaining property, initial alkaline absorption and durable alkaline absorption while maintaining tensile strength and air permeability, by forming functional groups or bonds of —CHO or —C+H—O−, —CO—, and —COO— or —COO−on the surface of the non-woven fabric. The battery shows great wettability with an alkaline electrolyte when incorporated into an battery, and thus, improves the battery life. The battery separator is provided by mixing and wet laid processing 15-75 weight % of splittable conjugated staple fibers comprising polyolefin polymer (component A) and ethylene vinyl alcohol copolymer (component B) arranged adjacent to each other when viewed in fiber cross section, 20-60 weight % of thermal bonding staple fibers, and 0-50 weight % of synthetic fibers that have greater fineness than that of ultra fine fibers formed by splitting the splittable bi-component fibers and have the same or smaller fineness than that of the thermal bonding fibers; treating the wet laid type non-woven fabric with high-pressure water flow to split the splittable bi-component fibers and to form the ultra fine fibers while entangling the fibers; treating both surfaces of the non-woven fabric with corona surface discharge, and calendering by heated rollers.
