MIXTURES SUITABLE AS SOLID ELECTROLYTES OR SEPARATORS FOR ELECTROCHEMICAL CELLS

摘要

The mixture (I) contains a mixture (II) consisting of: (a) 1-95 wt.% of a solid (III) having a primary particle size of 0.01-10 mu m; and (b) 5-99 wt.% of a polymeric composition (IV) obtained by polymerising: (b1) 5-100 wt.% of an ester (V) made of a multivalent alcohol (VI) containing carbon and oxygen atoms in the main chain, and at least one molecule per molecule alcohol (VI) of an alpha - beta unsaturated carboxylic acid (VII); and (b2) 0-95 wt.% of a further compound (VIII) having an average molecular weight of ≥ 5000 with polyether segments in main and side chains. The weight of mixture (II) to mixture (I) is 35-100 wt.%.
