Abstract: An outer cover of a pouch-style battery includes a nanoceramic coating. Constructing an outer cover including a nanoceramic coating may include forming a malleable layer, applying a sealing layer to an inside surface of the malleable layer, and applying the nanoceramic layer to an outside surface of the malleable layer. Fabricating an outer cover including a nanoceramic coating may further include applying a protective film to an outside surface of the outer cover, which may be removed shortly before or after installation of a battery cell for which the outer cover is manufactured. Fabricating an outer cover including a nanoceramic coating may also include applying one or more adhesive layers, for example an adhesive layer between the malleable layer and the sealing layer. An outer cover including a nanoceramic coating may be sealed around a battery-active-material assembly to form a pouch-style battery cell.
