Abstract
Provided are anodes for use in electrochemical cells, wherein the anode comprises an anode active layer comprising lithium and a polymer anode substrate comprising a polymer film layer and a protective crosslinked polymer layer, in which the protective crosslinked polymer layer is in contact with the anode active layer on the side opposite to the surface in contact with the polymer film layer. The present invention also pertains to methods for forming such anodes and electrochemical cells comprising such anodes.
Claims23
A method of preparing an anode of an electrochemical cell, wherein said anode is formed by the steps of:
- (a) depositing onto a polymer film layer a polymerizable layer comprising one or more monomers;
- (b) polymerizing said polymerizable layer of step (a) to form protective crosslinked polymer layer;
- and
- (c) depositing over said protective crosslinked polymer layer an anode active layer comprising lithium.
An anode of an electrochemical cell, wherein said anode comprises:
- (a) an anode active layer comprising lithium;
- and
- (b) a polymer anode substrate wherein said polymer anode substrate comprises a polymer film layer and a protective crosslinked polymer layer;
- wherein said protective crosslinked polymer layer is in contact with said anode active layer comprising lithium on the side opposite to the surface in contact with said polymer film layer.
An electrochemical cell comprising:
- (a) a cathode comprising a cathode active material;
- (b) an anode;
- and
- (c) a non-aqueous electrolyte interposed between said anode and said cathode, wherein said anode comprises:
- (i) an anode active layer comprising lithium;
- and
- (ii) a polymer anode substrate, wherein said polymer anode substrate comprises a polymer film layer and a protective crosslinked polymer layer wherein the protective crosslinked polymer layer is in contact with said anode active layer comprising lithium on the side opposite to the surface in contact with said polymer film layer.
