摘要： The present invention provides a battery or supercapacitor current collector which is prelithiated. The prelithiated current collector comprises: (a) an electrically conductive substrate having two opposed primary surfaces, and (b) a mixture layer of carbon (and/or other stabilizing element, such as B, Al, Ga, In, C, Si, Ge, Sn, Pb, As, Sb, Bi, Te, or a combination thereof) and lithium or lithium alloy coated on at least one of the primary surfaces, wherein lithium element is present in an amount of 1% to 99% by weight of the mixture layer. This current collector serves as an effective and safe lithium source for a wide variety of electrochemical energy storage cells, including the rechargeable lithium cell (e.g. lithium-metal, lithium-ion, lithium-sulfur, lithium-air, lithium-graphene, lithium-carbon, and lithium-carbon nanotube cell) and the lithium ion based supercapacitor cell (e.g, symmetric ultracapacitor, asymmetric ultracapacitor, hybrid supercapacitor-battery, or lithium-ion capacitor).
