Ionic Conductivities of Solid Polymer Electrolyte/Salt systems for Lithium Secondary Battery : Electro-Chemical Potential Contribution |
| 초록 |
We establish a group contribution model of ionic conductivities for solid polymer electrolyte/salt systems based on the Nernst-Einstein equation in which the diffusion coefficient is derived from the modified double-lattice model and the electro-chemical potential. The model includes three contributions: the combinatorial contribution which is responsible for entropy of mixing, the van der Waals energy contribution from dispersion and the polar forces, and the specific energy contribution. The proposed model takes into account both the mobility and the charge interactions of the salt and the polymer for given systems. Our model shows improved results for prediction when compared with those of other models. |
