Abstract
Batteries or fuel cells having at least two electrodes and an electrolyte are described in which at least one of the electrodes employs an ethylene-perhaloethylene copolymer as binder material. The copolymer binder aids in maintaining adequate electrode structural integrity.
Claims10
An energy cell comprising electrolyte, electrolyte solvent and electrodes, at least one of said electrodes comprising active material and binder;
- characterized in that said binder comprises copolymer with from about 40 to 60 mole percent of ethylene comonomer and from about 40 to 60 mole percent of halogenated ethylene comonomer in which the halogenated ethylene comonomer is comprised of at least one substance selected from the group consisting of tetrafluoroethylene and chlorotrifluoroethylene.
