Abstract
Official abstract text for this publication.
Disclosed is a negative electrode current collector for an anode-free lithium metal battery. The negative electrode current collector includes a PdTe 2 layer and an intermediate layer to inhibit the growth of lithium dendrite, resulting in significant improves in lifespan and performance of the lithium metal battery. The negative electrode current collector further includes an ion conductive layer to improve the performance of the lithium metal battery.
First claim
Opening claim text (preview).
What is claimed is: 1. An anode-free lithium metal battery comprising a cathode, a negative electrode current collector, an electrolyte, and a separator, wherein the negative electrode current collector comprises a transition metal dichalcogenide layer and a transition metal intermediate layer, wherein the transition metal dichalcogenide layer is made of a material satisfying the chemical formula “MX 2 ”, and the transition metal intermediate layer is made of a material satisfying the chemical formula “MX”, and wherein M is selected from the group consisting of Pd, Pt, Cu, Ag, and Au, and X is selected from the group consisting of S, Se, and Te. 2. The anode-free lithium metal battery of claim 1 , wherein the negative electrode current collector further comprises an artificial solid-electrolyte interface (SEI). 3. The anode-free lithium metal battery of claim 1 , wherein wherein the transition metal dichalcogenide layer has a thickness in a range of 2 to 20 nm. 4. The anode-free lithium metal battery of claim 2 , wherein the artificial SEI comprises lithium phosphorous oxynitride (LiPON).
