A battery separator in which plural sheets of microporous plastic material are connected by a strip or strips of polyvinylchloride in a manner suitable to form a sleeve. The strips may be high frequency heat sealed to the sheets or may be bonded thereto by solvating the outer edge portions of the strips, applying pressure between the strips and the sheets, and allowing the solvent to evaporate. A method of manufacturing a battery separator of the above type.

A battery separator comprising: (a) a pair of sheets of microporous plastic material disposed in a spaced parallel relationship; and (b) at least one first member of a thermoplastic material formed from a compressible solid strip having a top surface, a bottom surface, a pair of opposed side surfaces and a first size suitable for allowing said first member to fit between inner facing confronting surfaces of said pair of sheets, said first member being in a compressed condition whereupon said first member assumes a second size such that said top surface of said first member lies flush with upwardly facing surfaces of said pair of sheets and outer regions of said opposed side surfaces are urged against said confronting inner facing first surfaces of said pair of sheets, each outer region of each one of said opposed side surfaces of said first member being adhered to a corresponding one of said two confronting inner facing surfaces of said pair of sheets.
