PURPOSE:To improve the electrolyte retainability and absorbency of a separator and to increase its mechanical strength and hardness by containing a specified amount of aromatic polyamide fibers in a separator mainly comprising glass fibers. CONSTITUTION:A separator consists of glass fibers and aromatic polyamide fibers. The polyamide fiber having a diameter of 1.0-40mum and a length of 0.5-25mm is used. The content of aromatic polyamide fibers is 0.1-15wt%. As the glass fiber, acid-resistant, alkali-containing glass fiber having a mean diameter of 1mum or less is mainly used. |
