First claim
Opening claim text (preview).
What is claimed is: 1 . An hybrid inorganic/organic membrane comprising: a polymeric matrix; a plurality of ion-conducting particles disposed within the polymeric matrix, the plurality of ion-conducting particles forming ion conducting channels in the polymer matrix; and an inorganic coating deposited in the polymeric matrix, the inorganic coating being a uniform layer 1 to 10,000 atoms thick. 2 . The hybrid inorganic/organic membrane of claim 1 , wherein the inorganic coating is ion-permeable and the hybrid inorganic/organic membrane is impermeable to both aqueous and organic media. 3 . The hybrid inorganic/organic membrane of claim 1 , wherein the inorganic coating is covalently bonded. 4 . The hybrid inorganic/organic membrane of claim 1 , wherein the inorganic coating comprises a metal oxide. 5 . The hybrid inorganic/organic membrane of claim 1 , wherein inorganic coating comprises a material selected from the group consisting of alumina (Al 2 O 3 ), zirconia (ZrO 2 ) and zinc oxide (ZnO). 6 . The hybrid inorganic/organic membrane of claim 1 , wherein the polymeric matrix comprises a solid matrix with through-pores and further wherein each of the through-pores are filled with ion-conducting particles. 7 . The hybrid inorganic/organic membrane of claim 1 , wherein the ion-conducting particles comprise a material selected from crystalline solids and non-crystalline solids. 8 . The hybrid inorganic/organic membrane of claim 7 , wherein the crystalline solids are selected from the group consisting of LifePO 4 , lithium lanthanum zirconium oxide (LLZO), lithium titanium oxide (LTO), lithium cobalt oxide (LCO), and NASICON-type Li 2 O—Al 2 O 3 —SiO 2 —P 2 O 5 —TiO 2 . 4920 - 5538 - 8688 1 9 . The hybrid inorganic/organic membrane of claim 7 , wherein the non-crystalline solids comprise lithiated silica.
