The Grace DAKASEP separator was originally developed as a wicking layer for nickel-zinc alkaline batteries. DAKASEP is a filled, non-woven separator which is flexible and heat sealable. Through modification of formulation and processing variables, products with a variety of properties can be produced. Variations of DAKASEP have been tested in NiH2, NiZn, NiCd, and primary alkaline batteries with good results. Data are presented here for separators designed for ZnHgO primary batteries. Actual performance data for ZnHgO E-1 size cells are also included. © 1987.
