摘要

Nickel-cadmium or nickel metal hydride open accumulator, comprises an electrolyte with a positive electrode, a negative electrode and a separator, where the separator comprises a micro porous membrane of polyolefin, grafted by a monomer with unsaturated ethylene and a fibrous polyolefin layer on both sides of the membrane. An independent claim is included for a process of charging the open accumulator with constant voltage.
