07227 IUPAC Gold Book - solid polymer electrolyte 10.1351/goldbook.ST07227 ST07227 current 1 Electrically conducting solution of a salt in a polymer. An example of a solid @P04728@ is a solution of a lithium salt in a poly(oxyethylene) matrix; the ionic conductivity of such material is due to the mobility of lithium cations and their counterions in an electric field. Although the adjective 'solid' is used, the material may be a liquid. The term solid @P04728-1@ should not be confused with the term polymeric electrolyte. conducting polymer composite https://goldbook.iupac.org//terms/view/CT07201 ionic conductivity https://goldbook.iupac.org//terms/view/I03175 mobility https://goldbook.iupac.org//terms/view/M03955 polymeric electrolyte https://goldbook.iupac.org//terms/view/P04728 salt https://goldbook.iupac.org//terms/view/S05447 PAC, 2006, 78, 2067.
