Abstract
Official abstract text for this publication.
Methods for forming polymeric protective layers on magnesium anodes for magnesium batteries include placing a solution of electropolymerizable monomers onto all exposed surfaces of a magnesium anode, and electropolymerizing the monomers in the solution. The monomers can be glycidyl methacrylate, a salt of 3-sulfopropyl methacrylate, or a mixture of the two. Protected magnesium foam anodes for 3-D magnesium batteries have a magnesium foam electrolyte, and a polymeric coating covering all exposed surfaces of the magnesium foam electrolyte. The polymeric protective coating formed of (poly)glycidyl methacrylate, poly(3-sulfopropyl methacrylate), or a copolymer of the two.
First claim
Opening claim text (preview).
What is claimed is: 1. A protected foam magnesium anode, comprising: an open cell magnesium foam anode having a surface consisting of magnesium metal; and a polymeric protective layer coating the magnesium foam anode on substantially all surfaces, the polymeric protective layer comprising a polymer selected from the group consisting of: poly(potassium 3-sulfopropyl methacrylate); and a glycidyl methacrylate/potassium 3-sulfopropyl methacrylate copolymer. 2. The protected foam magnesium anode as recited in claim 1 , wherein the polymeric protective layer comprises poly(potassium 3-sulfopropyl methacrylate). 3. The protected foam magnesium anode as recited in claim 1 , wherein the polymeric protective layer comprises a glycidyl methacrylate/potassium 3-sulfopropyl methacrylate copolymer. 4. The protected foam magnesium anode as recited in claim 1 , wherein the open cell magnesium foam anode comprises an anode formed entirely of elemental magnesium. 5. The protected foam magnesium anode as recited in claim 1 , wherein the open cell magnesium foam anode comprises an anode formed of magnesium plated on a metal foam substrate. 6. The protected foam magnesium anode as recited in claim 5 , wherein the open cell metal foam substrate comprises copper foam.
