摘要： Voltage delay in an active metal anode/liquid cathode battery cell can be significantly reduced or completely alleviated by coating the active metal anode (e.g., Li) surface with a thin layer of an inorganic compound with Li-ion conductivity using chemical treatment of Li surface. Particularly, preferred examples of such compounds include lithium phosphate, lithium metaphosphate, and/or their mixtures or solid solutions with lithium sulphate. These compounds can be formed on the Li surface by treatment with diluted solutions of the following individual acids: H3PO4, HPO3 and H2SO4, their acidic salts, or their binary or ternary mixtures in a dry organic solvent compatible with Li, for instance in 1,2-DME; by various deposition techniques. Such chemical protection of the Li or other active metal electrode significantly reduces the voltage delay due to protected anode's improved stability toward the electrolyte.

摘要： Disclosed are dioxolane-treated lithium electrodes, battery cells containing such dioxolane-treated lithium electrodes, battery cell electrolytes containing dioxolane, and methods of treating lithium electrodes with dioxolane and battery cells containing such dioxolane-treated lithium electrodes. Treating lithium with dioxolane prevents the lithium from reacting with a wide range of substances which can contaminate battery cells, particularly moisture and other protic impurities, that might otherwise react with the lithium to the detriment of its function as a negative electrode in a battery cell. Battery cells containing dioxolane as an electrolyte co-solvent in accordance with the present invention exhibit improved cycling performance over cells not containing dioxolane. Moreover, the dioxolane treatment does not negatively impact sulfur utilization and improves the lithium's electrochemical function as the negative electrode in the battery cell.

摘要： Batteries including a lithium electrode and a sulfur counter electrode that demonstrate improved cycling efficiencies are described. In one embodiment, an electrochemical cell having a lithium electrode and a sulfur electrode including at least one of elemental sulfur, lithium sulfide, and a lithium polysulfide is provided. The lithium electrode includes a surface coating that is effective to increase the cycling efficiency of said electrochemical cell. In a more particular embodiment, the lithium electrode is in an electrolyte solution, and, more particularly, an electrolyte solution including either elemental sulfur, a sulfide, or a polysulfide. In another embodiment, the coating is formed after the lithium electrode is contacted with the electrolyte. In a more particular embodiment, the coating is formed by a reaction between the lithium metal of the lithium electrode and a chemical species present in the electrolyte.
