Abstract
The present invention concerns a new method for the preparation of a Li—P—S—O product, as well as the products obtainable by said methods, and uses thereof especially as solid electrolytes.
The invention relates to VDF polymer powders comprising primary particles having a median diameter in the range 15 to 50 microns and a total pore volume of 0.70 to 2.00 mL/g which are obtained by suspension polymerization. The powders can be used to form stable suspensions in water. The suspensions can be used in the preparation of articles such as components for batteries as well as membranes.
222222) particles to fluorinated polymers containing sulfonic acid functional groups increases their stability towards radical degradation when used in fuel cell applications or in electrolysis applications.
