چکیده

In this study, the amphiphilic salt lithium trifluoromethanesulfonylimide octadecane (C18LiTFSI) was used as a basis to investigate effects of anion density and cation coordination sites within blended electrolytes with strong ionic aggregation. C18LiTFSI previously reported single-component, ion-condensed electrolyte wide layered liquid crystalline phase regime. Three additive molecules varyingly sized polar sulfonyl groups attached an octodecane-tail were synthesized mixed C18LiTFSI. The thermal properties, morphology, conductivity characterized. It found that exhibited morphology over narrower temperature range than pure salt, generally lower salt. Surprising, additives have greatest effect on bulk semicrystalline electrolytes. Addition minor fractions methylsulfonyloctadecane resulted in increases two orders magnitude at room temperature, while addition ethylsulfonyloctadecane or isopropylsulfonyloctadecane larger head group decreased entire composition space investigated.

A Computer Simulation Study of Ionic Conductivity in Polymer Electrolytes

In this paper we present a computer simulation study of ionic conductivity in solid polymeric electrolytes. The multiphase nature of the material is taken into account. The polymer is represented by a regular lattice whose sites represent either crystalline or amorphous regions with the charge carrier performing a random walk. Different waiting times are assigned to sites corresponding to the d...
