An ionically conductive ion-containing gel having a bulk ionic conductivity at 20 DEG C and 10 KHz greater than 10<-4> Siemens/cm and a dynamic modulus at 10 Hz greater than 10<3> Pa, consists of a minor amount of a crystallisable polymer, a major amount of an organic compound that is not a solvent for the polymer at 20 DEG C, and a salt soluble in said compound at 20 DEG C and dissolved therein at a concentration greater than 4 % by mass based on said compound. The crystallisable polymer may be a polyamide, polyester, polyether or substituted polyolefin. The organic compound may be an amide, e.g. a tertiary amide, a sulphoxide or an ether. The salt is preferably of an alkali metal or of an optionally substituted ammonium with a monovalent anion, e.g. lithium trifluoromethane sulphonate. The gel can be used as an electrolyte in galvanic cells. |
