Disclosed are ion-conductive composites for protecting active metal anodes and methods for making them. The composite may be incorporated into an active metal negative electrode (anode) structure and battery cell. In accordance with the present invention, the properties of different ionic conductors are combined to give the overall favorable properties of high ionic conductivity and excellent chemical stability for the ambient conditions encountered during anode, cathode, and battery manufacturing. A realizable composite material is constructed. The composite provides a high level of ionic conductivity while protecting the active metal anode from harmful reactions with other components of the battery or ambient conditions, thereby producing a battery cell incorporating the composite. And / or improved performance. |
