    摘要： The invention provides an electrochemical cell comprising an electrolyte and a multi-layer article, the multi-layer article comprising a first electrode, a second electrode in ionically conductive contact with the first electrode, and a separator disposed between and in contact the first electrode and the second electrode. The separator comprises a nanoweb, the nanoweb comprising nanofibers of a cross-linked polyimide, wherein the cross-linked polyimide is derived from an aromatic dianhydride, an aromatic diamine, and a reactive end-capper. The reactive end-capper is at least one of a functionalized anhydride or a functionalized amine, functionalized with a reactive functionality selected from the group consisting of acetylene, vinyl, epoxide, nitrile, and ester. The electrochemical cell also comprises a first current collector in electrically conductive contact with the first electrode and a second current collector in electrically conductive contact with the second electrode.
