Patent
·
OSTI ID:6815185
An electrochemical cell is described comprising a container having two electrically isolated terminals. The container has therein an anode connected to one terminal, a cathode connected to the other terminal, a fluid electrolyte, an ionizable solute dissolved in the electrolyte, and a separator positioned between and in contact with the anode and the cathode. The separator is characterized by being a substantially continuous microporous film comprising a polymer that is a copolymer of ethylene and a fully halogenated analogue of ethylene.
