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.

研究了电极/固体电解质界面以开发全固态电池。讨论了电阻与某些活性材料中离子扩散公式的关系。研究了锂离子扩散系数的估算方法，电位阶跃法是估算锂离子扩散系数最合理的方法。结果表明，界面电阻按一维、二维、三维扩散路径电极的顺序减小。结果表明，三维扩散是降低界面电阻最有效的方法。
