A new and thermally stable gellan-based polymer electrolytes (PEs) with LiCF3SO3 were
prepared and characterized by spectroscopic (FTIR), thermal (TGA, DSC and DMA),
structural (X-ray), electrochemical stability (CV, and LSV) and ionic conductivity
measurements. The obtained results revealed that the samples are semicrystalline and are
thermally stable up to 234° C. The ionic conductivity measurements revealed that the ionic
conductivity of the electrolyte varies with the salt concentration to reach the highest …
