【Abstract】 In order to explore the performance index of nonwoven composite fiber separator of valve-regulated sealed lead-acid battery, five different fiber raw materials were selected and blended according to a certain ratio by wet web nonwoven, and the influence of different fiber content on the physical properties of the separator was tested. The test results showed that the maximum tensile strength, minimum maximum pore size and minimum pore ratio of polyvinyl alcohol fiber composite separator were lower than those of ordinary glass fiber, and the test data were 0.46 kN/m, 13.18 μm and 90.76% respectively. The maximum tensile strength and minimum maximum pore size of the polypropylene fiber composite separator were lower than those of ordinary glass fiber, and the test data were 0.446 kN/m and 13.33 μm. The maximum tensile strength, minimum maximum pore size and minimum resistance of polyacrylonitrile fiber composite separator were lower than those of ordinary glass fiber, and the test data were 0.368 kN/m, 19.79 μm, and 2×10^-3 Ω. The maximum tensile strength, minimum maximum pore size and minimum resistance values of kapok fiber composite separator were lower than those of ordinary glass fiber, and the test data were 0.418 kN/m, 13.78 μm, 2.6×10^-3 Ω. The physical properties of two-component polyester fiber composite separator were better than other composite fiber partitions, and the new composite fiber partition PG-2 made of 2D×10 mm two-component polyester fiber and 8.5 g 34°SR ultrafine glass fiber cotton with a fiber content of 1.5 g had better performance, and its standards exceeded the performance of pure glass fiber separator.更多还原
