Discovery of Argyrodite-type novel solid state electrolyte using a metaheuristic algorithm |
| 초록 |
High energy density and stability have been pursued for promising lithium-ion batteries. All-solid-state batteries using solid state electrolytes(SSEs) could be a suitable alternative to liquid electrolyte lithium-ion batteries to secure high energy density, working voltage and stability. In this study, we discover novel compositions in well-known argyrodite-type SSEs that have high ionic conductivity. A metaheuristic strategy, so-called particle swarm optimization(PSO), was used for the discovery of novel argyrodite-type SSEs. An optimum set of multi-anion doping and synthesis temperature was adopted to improve ionic conductivity in the metaheuristics search process. The compound that we discovered has been analyzed by synchrotron XRD and we tested half-cell and symmetric cell performances in various conditions, and finally identified the electrochemical property. |
