제목 | Phase behaviours of solid polymer electrolytes /Salt Systems in Lithium Secondary Battery by Group-contribution Method |
초록 | A molecular thermodynamic model based on the theory of melting point depression and the modified double-lattice theory are extend to the group contribution model to interpret phase behaviors of solid polymer electrolyte (SPE)/salt system with various temperatures and compositions. The group-contribution model includes the combinatorial energy contribution that is responsible for the revised Flory-Huggins entropy of mixing, the van der Waals energy contribution from dispersion, polar force and the specific energy contribution from hydrogen bonding. The liquidus curves in the resulting phase diagram and an eutectic point are predicted with various temperatures and compositions. Quantitative description according to proposed model is in good agreement with the experimentally observed transition temperature of a given system an eutectic point. |
