The present invention is directed to compositions useful for use in separators for use in lithium ion batteries, and membranes, separators, and devices derived therefrom. 1. A block copolymer comprising at least a first and second block , said second block copolymer comprising a polymerized ionic liquid , said polymerized ionic liquid being stable in the presence of aqueous hydroxide , and wherein said block copolymer composition exhibits at least one region of nanophase separation.2. The block copolymer of claim 1 , wherein at least one region of nanophase separation is characterized by at least one region of a periodic nanostructured lamellar morphology with connected ion-conducting domains.3. The block copolymer of claim 2 , wherein the connected ion-conducting domains extend in three-dimensions throughout the block copolymer.4. The block copolymer of claim 2 , wherein the periodicity of the nanostructured lamellar morphology is characterized by ordered domains having lattice parameter dimensions in the range of about 5 to about 50 nm claim 2 , as measured by small angle X-ray scattering.5. The block copolymer of claim 2 , wherein the block copolymer is a diblock copolymer.6. The block copolymer of claim 2 , wherein the first block comprises polymers or copolymers comprising an acrylate claim 2 , methacrylate claim 2 , styrene claim 2 , or vinylpyridine derivative claim 2 , or a combination thereof.7. The block copolymer of claim 2 , wherein the first block comprises a polymer or copolymer comprising a styrene derivative.8. The block copolymer of claim 2 , wherein the first block comprises a polymer or copolymer comprising an acrylate or methacrylate derivative.10. The block copolymer of claim 9 , wherein Rand Rare both H.11. The block copolymer of claim 9 , wherein both Rand Rare both Calkyl.12. The block copolymer of claim 9 , wherein Rand Rare both H and Rand Rare both methyl.13. The block copolymer of claim 2 , wherein the first block has an average molecular ...
