NOVELTY - A prelithiated lithium cell current collector (T1) comprises an electrically conductive substrate (100, 104) having two opposed primary surfaces; and a mixture layer of lithium or its alloy with a stabilizing agent, where the mixture layer is coated on at least one of primary surface, and contains lithium element in an amount of 1-99 wt.%.    USE - In an electrochemical cell including lithium cell, lithium-ion battery and lithium-metal battery (claimed); and also used as lithium source for a wide variety of electrochemical energy storage cells including the rechargeable lithium cells, e.g. lithium-sulfur, lithium-air, lithium-graphene, lithium-carbon and lithium-carbon nanotube cell, and the lithium ion based super-capacitor cells e.g. symmetric ultracapacitor, asymmetric ultracapacitor, hybrid super-capacitor-battery, or lithium-ion capacitor.    ADVANTAGE - The prelithiated current collector is conducive to the mass production of high-energy and/or high-power cells in a real large-scale manufacturing environment; can be designed and made to be used at either the anode or the cathode side of a cell; is more air stable, safer, and easier to handle, where the prelithiated anode has a relatively limited lithium content; and is capable of designing and constructing battery cells having high energy density. The use of a prelithiated current collector enables the use of non-prelithiated cathode materials that typically have a much higher specific capacity as compared to the conventional lithiated cathode active materials commonly used in lithium-ion and lithium-metal secondary battery cells. The battery cell does not contain a sacrificial electrode or an extra electrode in addition to an anode and a cathode in a cell; and provides a convenient source of lithium to compensate for the formation of solid-electrolyte interface (SEI) layers during charging, in addition to providing enough lithium to intercalate into a cathode active material during discharging. The battery features a long and stable cycle life due to an adequate supply of lithium to compensate for potentially continued irreversible consumption of lithium. The battery cell comprises an anode that does not contain an unstable lithium metal phase or lithium metal powder particles dispersed in the anode.
