ABSTRACT:
The use of a paper containing synthetic fiber not greater than 0.8 denier, particularly a paper consisting of a polyvinyl alcohol fiber not greater than 0.8 denier and a cellulosic fiber, as a separator in an alkaline dry cell is conductive to improved alkali resistance, greater alkaline electrolyte absorption, and prevention of an internal short-circuit, resulting in a marked improvement in the discharge capacity of the dry battery.
