(b) milling the mixture with a milling media to produce a milled mixture;
(c) adding a binder and a plasticizer to the milled mixture;
(d) milling the binder, plasticizer and milled mixture to produce a LLZO slurry;
(e) removing air in the LLZO slurry to prevent pin holes;
(f) tape casting the LLZO slurry on a substrate to form a LLZO tape;
(g) removing the binder from the cast LLZO tape; and
(h) sintering the LLZO tape after binder removal.
