  • High purity lithium and associated processes
    Patent number: 11076981
    Abstract: High purity lithium and associated products are provided. In a general embodiment, the present disclosure provides a lithium metal product in which the lithium metal is obtained using a selective lithium ion conducting layer. The selective lithium ion conducting layer includes an active metal ion conducting glass or glass ceramic that conducts only lithium ions. The present lithium metal products produced using a selective lithium ion conducting layer advantageously provide for improved lithium purity when compared to commercial lithium metal. Pursuant to the present disclosure, lithium metal having a purity of at least 99.96 weight percent on a metals basis can be obtained.
    Type: Grant
