COLLOID ELECTROLYTE COMPOSITION

摘要

The invention relates to a colloidal electrolyte composition comprising a polyelectrolyte selected from one or more cationic polymers, a particulate phase forming a colloidal dispersion, and a binder system able to form a cross-linked network upon curing the electrolyte composition. Also, the invention relates to a method of preparation the colloidal electrolyte composition, to an electrochemical cell and to a method of preparation the electrochemical cell.

主权项

1. An electrolyte composition in form of a colloidal dispersion comprising:
a) polyelectrolyte selected from one or more cationic polymers being quaternized nitrogen containing compounds selected from the group consisting of copolymer having quaternized vinylimidazolium repeating units and poly(diallyldimethyl ammonium chloride) or copolymers thereof; b) a particulate phase comprising solid particles having a diameter of between 1 to 10000 nm and being inert to the other components included in the electrolyte composition; and c) a binder system comprising binder molecules able to form a polymeric network upon radical polymerization, and initiator molecules able to initiate radical polymerization of the binder molecules, said binder molecules being polyfunctional and monofunctional acrylates or methacrylates, or being di- or polyfunctional thiols and molecules having double bonds; wherein said polyelectrolyte is substantially absent of groups that are readily polymerizable under conditions of radical polymerization.
