✦ Synopsis
Room temperature molten salts consisting of 1-butylpyridinium halide (chloride or bromide) and aluminium chloride have been utilized as electrolytes for a new class of highly conductive polymer electrolytes. Poly(l-butyl-4-vinylpyridinium halides) (chloride and bromide), which are polymer analogues of the pyridinium salts, are compatible with the molten salts to form polymer electrolytes. The addition of small amount of the polypyridinium salts imparts viscoelastic rubbery property to the polymer electrolytes. The ionic conductivity is much influenced by the composition of the polymer electrolytes and temperature, and the high conductivity comparable to that of the molten salts is attained.
