PROTON CONDUCTOR IN LIQUID FORM

摘要

Disclosed is a proton conductor in liquid form, comprised of a mixture of the following components: (a) a salt combined with a nitrogenated base along with an acid, according to formula (I), wherein Z1, Z2, Z3, and Z4, whether identical or different, represent a group -N= or -C(Zi)=, wherein Zi represents a hydrogen atom, a linear or branched alkyl radical with from 1 to 20 carbon atoms, a fluoroalkyl radical with from 1 to 20 carbon atoms, or an oxoalkyl or azaalkyl radical with from 1 to 20 carbon atoms, as long as at least one and at most two of the groups Z1, Z2, Z3, and Z4 represent -N=; two adjacent carbon atoms are possibly hydrogenated; the nitrogenated base possibly forms part of a polymeric matrix; and X<-> represents an anion derivative of an acid selected from the group formed by the sulphonic acids of the formula R3F2<) (R'>F2<)NH and the methylures of the formula (R>F2<) (R'>F2<)CH>2< or (R>F2<) (R'>F2<) (R">F2<)CH, wherein R>F<, R'>F< or R">F< independently represent a radical F(CF>2<)>n<-, n being comprised between 0 and 6, and the acid possibly forming part of a polymeric matrix; and (b) a nitrogenated base according to formula (II), wherein Z>1<, Z>2<, Z>3<, and Z>4< have the above-mentioned significance, and the nitrogenated base is possibly part of a polymeric matrix. The components (a) and (b) are present in proportions allowing for the formation of a composition with a melting point of less than 25 DEG C. The proton conductor disclosed in the invention can be used as a liquid, gel, or polymer electrolyte in various electrochemical systems.
