摘要

"ELECTROCHEMICAL DEVICE COMPONENT, PROTECTIVE COMPOSITE BATTERY SEPARATOR, METHOD FOR MANUFACTURING AN ELECTROCHEMICAL DEVICE COMPONENT, AND METHOD FOR PRODUCING THE SAME". Ionically conductive composites for protection of active metal anodes and methods for their manufacture are disclosed. The composites can be incorporated into negative active metal (anode) electrode structures and battery cells. According to the invention, the properties of different ionic conductors are combined into a composite material that has the desired properties of high ionic conductivity and overall anode-sense chemical stability, cathode and ambient conditions encountered in battery manufacture. The composite is capable of protecting an active metal anode against deleterious reaction with other battery components or ambient conditions, while providing a high level of ion conductivity to facilitate fabrication and / or improve the performance of a battery cell. in which the composite is incorporated.
