  • Publication number: 20170155169
    Abstract: Ceramic ion-conducing structures are disclosed. The structures can be in the form of a single layer or multilayer structures. A ceramic ion-conducting structure can be a layer. In an example, the ceramic ion-conducing material does not have observable dendrites (e.g., lithium dendrites). Methods of fabricating ceramic-ionic conducing structures are also disclosed. The methods are based on particular slurry formulation methods and/or particular sintering methods. The methods can be tape casting methods. Uses of ceramic ion-conducing structures are disclosed. For example, the ceramic ion conducing structures can be used as solid-state electrolyte materials in ion-conducing batteries (e.g., solid-state ion-conducing batteries). An ion-conducting battery can comprise ion-conducting solid state electrolyte comprising one or more ceramic ion conducing material of the present disclosure.
