Aquivion® D79-25BS-Li is a chemically-stabilized (denoted by the S-suffix) perfluorosulfonic acid (PFSA) lithium salt dispersion that exhibits an Equivalent Weight (EW) of 790 g/eq. Polymer concentration is 25 percent. Solvent system is >99% water and is free of ethers. Aquivion® PFSA lithium salt dispersion is based on the Short Side Chain copolymer of Tetrafluoroethylene (TFE) and Sulfonyl Fluoride Vinyl Ether (SFVE) F2C=CF-O-CF2CF2-SO2F. The resulting perfluoropolymer's functional groups are in their lithium sulfonate form, (-SO3Li). Once formulated with solvents, Aquivion® D79-25BS-Li can be used for the preparation of cast films or coatings on various substrates. Formulations with volatile and non-volatile additives can be used to make components for electrochemical devices.
