摘要
PROBLEM TO BE SOLVED: To prevent a battery life from being shortened by lowering of the hydrophilicity by giving a high specific surface area to a separator of glass fiber, without substantially lowering mechanical strength and a tightening pressure after injecting an electrolyte. SOLUTION: This separator for the sealed lead-acid battery is formed mainly of glass fiber. A surface roughening treatment is applied to the fiber surface of glass fiber and/or glass fiber with a hollow structure, and which is used for at least a part of the glass fiber for the separator.
