Abstract
Official abstract text for this publication.
The invention comprises an anode-free lithium metal cell having an anode-side current collector composed of lithium, a lithium alloy or lithium-containing compound or a transition metal having a lithium or lithium alloy or lithium-containing compound surface coating, to provide a specific energy of the cell of 350 Wh/kg or greater.
First claim
Opening claim text (preview).
We claim: 1 . An anode-free lithium battery comprising: a cathode having a cathode current collector, an anode current collector; and a layer of separator/electrolyte disposed between the cathode and the anode current collector; wherein the anode current collector is a composition having a lithium adsorption energy between −0.1 eV and 0.1 eV. 2 . The battery of claim 1 wherein the composition of the anode current collector is a lithium alloy or a lithium compound 3 . The battery of claim 1 wherein the battery has a specific energy of 350 Wh/kg or greater. 4 . An anode-free lithium battery comprising: a cathode having a cathode current collector, an anode current collector; and a layer of separator/electrolyte disposed between the cathode and the anode current collector; wherein the anode current collector is a composition having a lithium diffusion energy between 0 eV and 0.1 eV. 5 . The battery of claim 4 wherein the composition of the anode current collector is a lithium alloy or a lithium compound. 6 . The battery of claim 4 wherein the battery has a specific energy of 350 Wh/kg or greater. 7 . An anode-free lithium battery comprising: a cathode having a cathode current collector, an anode current collector; and a layer of separator/electrolyte disposed between the cathode and the anode current collector; wherein the anode current collector is a layer of a transition metal having a surface layer of a composition having a lithium adsorption energy between −0.1 eV and 0.1 eV. 8 . The battery of claim 7 wherein the transition metal is copper. 9 . The battery of claim 8 wherein the composition of the surface layer is a lithium alloy or a lithium compound. 10 . The battery of claim 7 wherein the battery has a specific energy of 350 Wh/kg or greater. 11 . An anode-free lithium battery comprising: a cathode having a cathode current collector, an anode current collector; and a layer of separator/electrolyte disposed between the cathode and the anode current collector; wherein the anode current collector is a layer of a transition metal having a surface layer of a composition having a lithium diffusion energy between 0 eV and 0.1 eV. 12 . The battery of claim 11 wherein the transition metal is copper. 13 . The battery of claim 12 wherein the composition of the surface layer is a lithium alloy or a lithium compound. 14 . The battery of claim 11 wherein the battery has a specific energy of 350 Wh/kg or greater.
