Method for producing a separator material for rechargeable alkaline batteries

Abstract

A method for producing a separator material for rechargeable alkaline batteries. The method includes providing a base material, forming a polymer having a molecular structure that includes at least one functional group having a titrimetrically determined binding property for ammonia of at least 0.3 mmole NH3/g polymer powder. The method further includes introducing the polymer in particle form to the base material in a quantity of 1 to 50 g/m2. In addition, a separator material that includes a base material and a polymer disposed on the base material in particle form. The polymer includes a molecular structure that includes at least one functional group having a titrimetrically determined binding property for ammonia of at least 0.3 mmole NH3/g polymer powder.
