The ionic conductive dendrimer electrolytes, prepared by the terminal alkali-metal (Li+, Na+, K+) carboxylation of poly(amidoamine) (PAMAM) of generation 2.5 and 3.5, exhibit a conductivity of 10(-5)-10(-6) S cm(-1) at 30 degrees C The temperature and frequency dependence of ion conductivity are investigated. It is found that the temperature dependence fits neither the WLF mechanism nor the Arrhenius equation; this is attributed to the unique molecular structure of the dendrimer. Blending of lithium carboxylated PAMAM with lithium perchlorate is carried out and results in improved conductivity.
