PURPOSE:To improve the diffusion of an electrolyte in increasing the performance by gradually increasing or decreasing the vate of mixing synthetic resin fiber from one side toward the other side of a separator of lead-acid battery formed by mixing the sinthetic resin fiber with glass fiber. CONSTITUTION:30-90% glass fibers having a mean diameter of 0.3-30mu are mixed with synthetic resin fibers, which are acid resistant and oxidization resistant, comprising 0.3-3 denier monofilament. A mixing ratio of the synthetic resin is gradually varied from one side 1a toward the other side 1b, and a small amount of binder is mixed with the mixture, then a nonwoven fabric sheet is formed by a dry process. Or, by a wet process, a separator is formed with a cylindrical paper machine so that a mixing ratio of the synthetic fibers is gradually increased to the machine surface side. The side 1a of the separator, which has a large mixing ratio of synthetic fibers,is brought into contact with an anode, and the other side 1b is brought into contact with a cathode, and a plate group is assembled to form a sealed lead-acid battery. Thereby, the gas absorption in the anode and the electrolyte supply to the cathode are improved to remarkably increase the performance of the battery. |
