Graphene-protected lithiophilic or nathiophilic metal anode for an alkali metal battery

Abstract

Provided is an anode electrode (e.g. a layer or roll of a laminated structure) for a lithium battery or sodium battery, the anode electrode comprising: (a) an anode current collector having two primary surfaces; (b) multiple particles or coating of a lithium-attracting metal or sodium-attracting metal deposited on at least one of the two primary surfaces, wherein the lithium-attracting metal or sodium-attracting metal, having a diameter or thickness from 1 nm to 10 μm, is selected from Au, Ag, Mg, Zn, Ti, K, Al, Fe, Mn, Co, Ni, Sn, V, Cr, an alloy thereof, or a combination thereof; and (c) a layer of graphene that covers and protects the multiple particles or coating of the metal. Also provided is a process for producing such an anode electrode and a battery cell.

Dependencies are inferred from the claim text.
