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.
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.
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) CF
2=CF
2-O-(CF
2)
2-SO
2F industrially produced by Solvay Specialty Polymers. The resulting perfluoropolymer′s functional groups are in their lithium sulfonate form, SO
3Li. 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-SO
3Li) of low equivalent weight (EW) 790 g/mole SO
3H 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 "CF
3" configuration.
