| Research Abstract |
Electrode/solid electrolyte interfaces were studied for development of all solid-state batteries. The resistance was discussed about its correlation to ion diffusion formula in some active materials. The appropriate technique was investigated to estimate lithium ion diffusion coefficient, and potential-step was the method to give the most reasonable result. As a result, the interfacial resistance decreased in the order of electrode with one, two, three dimensional diffusion pathways. It is concluded that three dimensional diffusion is most effective to reduce the interfacial resistance.
