Subjects: BASIC ELECTRIC ELEMENTS ; ELECTRICITY ; IMPREGNATING OR COATING OF PAPER ; PAPER NOT OTHERWISE PROVIDED FOR ; PAPER-MAKING ; PREPARATION THEREOF NOT COVERED BY SUBCLASSES D21C OR D21D ; PROCESSES OR MEANS, e.g. BATTERIES, FOR THE DIRECT CONVERSIONOF CHEMICAL INTO ELECTRICAL ENERGY ; PRODUCTION OF CELLULOSE ; PULP COMPOSITIONS ; TEXTILES ; TREATMENT OF FINISHED PAPER NOT COVERED BY CLASS B31 OR SUBCLASS D21G
Description: A paper web for use in making a battery separator is formed from a furnish contg. a synthetic pulp; the fibrils of the pulp are filled with an inorganic filler, and the web incoporates a wetting agent. The web is formed on a paper-making machine, and is cheap and homogeneous. The electrical resistance across the separator is low, partic, after extended life in a battery. The pore size is lower, the distribution of pore size is narrower and the porosity is higher than in paper sheets made from wood pulp. The web can be consolidated by heat, and can be embossed to form projections.
