A lithium ion-conductive solid electrolyte including a freestanding inorganic vitreous sheet of sulfide-based lithium ion conducting glass is capable of high performance in a lithium metal battery by providing a high degree of lithium ion conductivity while being highly resistant to the initiation and/or propagation of lithium dendrites. Such an electrolyte is also itself manufacturable, and readily adaptable for battery cell and cell component manufacture, in a cost-effective, scalable manner. An automated machine based system, apparatus and methods assessing and inspecting the quality of such vitreous solid electrolyte sheets, electrode sub-assemblies and lithium electrode assemblies can be based on spectrophotometry and can be performed inline with fabricating the sheet or web (e.g., inline with drawing of the vitreous Li ion conducting glass) and/or with the manufacturing of associated electrode sub-assemblies and lithium electrode assemblies and battery cells.

Active metal and active metal intercalation electrode structures and battery cells having ionically conductive protective architecture including an active metal (e.g., lithium) conductive impervious layer separated from the electrode (anode) by a porous separator impregnated with a non-aqueous electrolyte (anolyte). This protective architecture prevents the active metal from deleterious reaction with the environment on the other (cathode) side of the impervious layer, which may include aqueous or non-aqueous liquid electrolytes (catholytes) and/or a variety electrochemically active materials, including liquid, solid and gaseous oxidizers. Safety additives and designs that facilitate manufacture are also provided.

Solid-state laminate electrode assemblies and various methods for making the solid-state laminate electrode assemblies involve a lithium metal layer reactively bonded to a lithium ion conducting sulfide glass layer. During manufacture, highly reactive surfaces of the lithium metal layer and the lithium ion conducting sulfide glass layer are maintained in its substantially unpassivated state until they have been reactively bonded.

Safety enhanced li-ion and lithium metal battery cells having protected lithium electrodes with enhanced separator safety against dendrite shorting

A water activated lithium battery cell having a thermal agent component for warming up cell components upon deployment. Also a water-activated battery system that is adapted to operate in and/or on the surface of a waterbody (i.e., a body of water including those which are natural or man made). In various embodiments the battery system comprises an operably breachable hermetic enclosure and at least one lithium battery cell having an open-cathode architecture, the lithium cell disposed inside the hermetic enclosure and therein maintained in an open ionic circuit condition (i.e., an inactive state) throughout battery system storage. Moreover, optionally, a thermal agent may be disposed inside the hermetic enclosure for warming up one or more battery cell components, the agent typically water activated, which is to mean that it (the thermal agent) evolves heat by reacting with water.
