摘要: Abstract We establish a new group-contribution model based on the Nernst–Einstein equation in which diffusion coefficient is derived from modified double-lattice (MDL) and Debye–Huckel (DH) theory. The includes combinatorial energy contribution that responsible for revised Flory–Huggins entropy of mixing, van der Waals dispersion, polar force specific hydrogen bonding. takes into account mobility salt motion polymer host. To describe segmental chain, well known conduction mechanism solid electrolyte (SPE) systems, effective co-ordinated unit parameter introduced. Our results show good agreement obtained upon comparison with experimental data various PEO systems interested ranges.
