PURPOSE:To obtain a separator free of shrinkage and adhering to terminal plates when impregnated with liquid, and spreading an electrolyte uniformly by letting a glass fibre sheet contain an inorganic laminated compound which swells at the time of impregnation. CONSTITUTION:As one of the inorganic laminated compounds which swell when a glass fibre sheet containing such compounds is impregnated with liquid, it is possible to mention mica. Also, if the ratio of inorganic laminated compound to glass fibre sheet is 5wt% minimum, the effect of its adhesion to the terminal plates is improved, but it is preferable to keep the upper limit of the ratio at about 50wt% for avoiding an unnecessary rise in the electric resistance of the separator and from an economical point of view. |
