Filed:

Mar 18, 2004

Appl. No.:

10/803710

Inventors:

Jill Watson - Mars PA, US
C. Wensley - Lakeland FL, US

International Classification:

H01M002/16

US Classification:

429144000, 429255000, 429250000

Abstract:

The instant invention is a separator for a battery having a zinc electrode. The battery separator according to the instant invention includes a microporous membrane, and a coating on at least one surface of the microporous membrane. The coating includes a mixture of 25-40 weight % polymer and 60-75 weight % surfactant combination. The polymer is cellulose acetate, and the surfactant combination includes a first surfactant and a second surfactant. The first surfactant, preferably, has an active ingredient selected from the group consisting of organic ethers, and the second surfactant is, preferably, an oxirane polymer with 2-ethylhexyl dihydrogen phosphate.
