An anode for an electrochemical cell comprises a lithium metal or lithium metal alloy, and a polymer coating deposited on the lithium metal or lithium metal alloy. The polymer coating is doped with lithium ions and comprises a polyisocyanurate material. The polyisocyanurate material contains ether- and/or silicone-containing further groups. The ether-containing group is a polyether, and/or wherein the silicone-containing group is a siloxane group.
