Abstract: 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.

Abstract: A functionalized lithium anode for batteries, which is obtainable according to a specific process using diazonium salts. The embodiments also relate to the use of that lithium anode in cells, to a cell including that lithium anode, to the use of that cell in an electronic device, and to an electronic device including that cell.

Abstract: The present invention relates to an anode for an electrochemical cell, said anode comprising a lithium metal or lithium metal alloy, and a polymer coating deposited on the lithium metal or lithium metal alloy, wherein the polymer coating is doped with lithium ions and comprises a polyisocyanurate material.

Abstract: A lithium-sulphur cell comprising an anode comprising lithium metal or lithium metal alloy, a cathode comprising a mixture of electroactive sulphur material and solid electroconductive material, an electrolyte comprising a tetrafluoroborate salt and an organic solvent, wherein the tetrafluoroborate salt is present in the electrolyte at a concentration of 0.05 to 0.5M, and wherein the tetrafluoroborate salt is present in an amount, wherein the molar ratio of tetrafluoroborate anion, BF4, to sulphur, S, in the electroactive material is 0.009-0.09:1.
