Uses

Aquivion^? PW79S-Li can be used, amongst other, in chemical or electrochemical structures or devices where Lithium ion conductivity of a solid conductor is requested. The powder can be mechanically processed into blends, films or coated on substrates, preferably accompanied or followed by a heat treatment. For casting processes Aquivion^? D79-25BS-Li dispersion is a more recommendable ingredient.

Uses

Once formulated with solvents Aquivion^? D79-25BS-Li can be used for the preparation of cast films or membranes, of coatings on various substrates. Formulations with volatile and non-volatile additives to make components for electrochemical devices are another possible way of using D79-25BS-Li.

General Description

Aquivion^? D79-25BS-Li is a dispersion based on the short-side-chain (SSC) copolymer of Tetrafluoroethylene and the Sulfonyl Fluoride Vinyl Ether (SFVE) CF₂=CF₂-O-(CF₂)₂-SO₂F industrially produced by Solvay Specialty Polymers. The resulting perfluoropolymer′s functional groups are in their lithium sulfonate form, SO₃Li. Aquivion^? D79-25BS-Li is delivered as a colloidal dispersion in highly pure deionized water. It contains the perfluoropolymer′s neutral lithium salt form (R-SO₃Li) of low equivalent weight (EW) 790 g/mole SO₃H at very high solid content of 25 % by weight which allows a large variety of subsequent formulations without additional pre-concentration steps. D79-25BS-Li contains "chemically stabilized" perfluoropolymer in which a large amount of polymer end groups are converted to their inert "CF₃" configuration.
