An investigation on LiCF3SO3 dopep plasticizer as potential solid electrolyte for lithium batteries

Abstract

Using the solution cast technique, solid polymer electrolytes composed of chitosan and PEO as the host polymer and lithium triflate (LiCF3S03) as the doping salt were prepared. Propylene carbonate (PC) and ethylene carbonate (EC) as a plasticizer was added to the solutions, respectively. The conductivity and dielectric behavior of plasticized chitosan/PE0-30 wt.% LiCF3S03 were studied from 42 Hz to I MHz at room temperature by EIS. For EC complexes, the highest conductivity was obtained at 50 wt.% (2.93 x 10-5 Siem) and 15 wt.% (8.89 x 10-6
