摘要
There are several problems left to be solved for the practical use of an all-solid-state lithium-ion battery (ASSLIB) such as the inhomogeneous reaction of active materials due to the intermittent ion/electron conduction pathway. In this study, a triple-microband electrode was embedded in the composite positive electrode of ASSLIB for the direct measurement of the reaction distribution of active materials. We found that the balance of the ionic/electronic conductivity of the composite electrode determines the reaction distribution in the depth direction of the composite electrode. Moreover, the active material was utilized equally even in the composite electrode, which has balanced ionic/electric conductivity and 300 mu m thickness.
