Electrochemical capacitor |
摘要 |
An electrochemical capacitor includes a positive electrode, a negative electrode disposed proximally to the positive electrode, and a non-aqueous electrolyte, wherein the positive electrode and the negative electrode are immersed in the non-aqueous electrolyte, and a case is presented in the energy storage system to accommodate the non-aqueous electrolyte, the positive electrode, and the negative electrode. The positive electrode has a porous matrix having a plurality of micrometer sized pores and nanostructured metal oxides, wherein the porous matrix is a 3-dimensional (3D) mesoporous metal or a 3D open-structured carbonaceous material, and the nanostructured metal oxides are coated inside the plurality of pores of the porous matrix. The non-aqueous electrolyte includes organic compounds having at least one acylamino group and lithium salts characterized as LiX, wherein Li is lithium and X comprises SCN−; the organic compounds are cyclic compounds; and the cyclic compounds comprise 2-oxazolidinone, ethyleneurea, or the combination thereof. |

1. An electrochemical capacitor, comprising:
a positive electrode, including:
a porous matrix having a plurality of micrometer sized pores, wherein the porous matrix is a 3D mesoporous metal or a 3D open-structured carbonaceous material; andnanostructured metal oxides coated inside the plurality of pores of the porous matrix; a negative electrode disposed proximal to and not in contact with the positive electrode; a non-aqueous electrolyte, including:
organic compounds having at least one acylamino group; andlithium salts characterized as LiX, wherein Li is lithium and X comprises SCN−;the organic compounds are cyclic compounds; andthe cyclic compounds comprise 2-oxazolidinone, ethyleneurea, or the combination thereof; a case accommodating the non-aqueous electrolyte, the positive electrode, and the negative electrode; wherein the positive electrode and the negative electrode are immersed in the non-aqueous electrolyte. |
