Abstract:
1. An electrochemical device component, comprising: an active metal electrode having a first surface and a second surface; and a handle-able composite protective membrane on the first surface of the electrode and having a gap-free interface therewith, the composite protective membrane being ionically conductive and chemically compatible with the active metal on a side in contact with the active metal electrode, and substantially impervious, ionically conductive and chemically compatible with active metal corrosive environments on the other side, the membrane comprising a substantially impervious sintered ceramic or glass-ceramic layer having a thickness between 10 and 1000 microns; wherein the ionic conductivity of the membrane is at least 10 wherein the device component can be handled or stored in normal ambient atmospheric conditions without degradation prior to incorporation into an electrochemical device.
