Publication number: 20060281003Abstract: The invention proposes an open alkaline accumulator of the nickel cadmium or nickel metal hydride type comprising at least one positive electrode, at least one negative electrode and at least one separator, said separator comprising a microporous membrane of polyolefin grafted with an ethylenically unsaturated monomer, and on either side of said membrane, at least one layer of polyolefin with a fibrous structure. Said accumulator has a lesser risk of thermal runaway upon charging at constant voltage, and a longer life time. The invention lies in the discovery that the use of a microporous membrane of polyolefin grafted with an ethylenically unsaturated monomer in an open alkaline accumulator of the nickel cadmium or nickel metal hydride type, provides a barrier to oxygen gas. The invention is extended to the method for charging at constant voltage said alkaline accumulator.Type: ApplicationFiled: May 31, 2006Publication date: December 14, 2006Applicant: SAFTInventors: Georges Caillon, Bernard Crochepierre
