摘要： Active metal and active metal intercalation electrode structures and battery cells having ionically conductive protective architecture including an active metal (e.g., lithium) conductive impervious layer separated from the electrode (anode) by a porous separator impregnated with a non-aqueous electrolyte (anolyte). This protective architecture prevents the active metal from deleterious reaction with the environment on the other (cathode) side of the impervious layer, which may include aqueous or non-aqueous liquid electrolytes (catholytes) and/or a variety of electrochemically active materials, including liquid, solid and gaseous oxidizers. Safety additives and designs that facilitate manufacture are also provided.

摘要： A high performance lithium-sulfur battery cell includes the following features: (a) a negative electrode including a metal or an ion of the metal; (b) a positive electrode comprising an electronically conductive material; and (c) a liquid catholyte including a solvent and dissolve electrochemically active material comprising sulfur in the form of at least one of a sulfide of the metal and a polysulfide of the metal. Such battery cells are characterized by an energy density, calculated based upon a laminate weight, of at least about 400 Watt-hours/kilogram when discharged at a rate of at least 0.1 mA/cm2. Cells meeting these criteria often find use as primary cells.

摘要： Disclosed are electrolyte solvents for ambient-temperature lithium-sulfur batteries. The disclosed solvents include at least one ethoxy repeating unit compound of the general formula R1(CH2CH2O)nR2, where n ranges between 2 and 10 and R1 and R2 are different or identical alkyl or alkoxy groups (including substituted alkyl or alkoxy groups). Alternatively, R1 and R2 may together with (CH2CH2O)n form a closed ring. Examples of linear solvents include the glymes (CH3O(CH2CH2)nCH3). Some electrolyte solvents include a donor or acceptor solvent in addition to an ethoxy compound as described. Examples of donor solvents include hexamethylphosphoramide, pyridine, N,N-diethylacetamide, N,N-diethylformamide, dimethylsulfoxide, tetramethylurea, N,N-dimethylacetamide, N,N-dimethylformamide, tributylphosphate, trimethylphosphate, N,N,N',N'-tetraethylsulfamide, tetramethylenediamine, tetramethylpropylenediamine, and pentamethyldiethylenetriamine. These assist in solvation of lithium ions. Examples of acceptor solvents include alcohols, glycols, and polyglycols. These assist in solvation of the sulfide and polysulfide anions.

摘要： A method for forming lithium electrodes having protective layers involves plating lithium between a lithium ion conductive protective layer and a current collector of an "electrode precursor." The electrode precursor is formed by depositing the protective layer on a very smooth surface of a current collector. The protective layer is a glass such as lithium phosphorus oxynitride and the current collector is a conductive sheet such as a copper sheet. During plating, lithium ions move through the protective layer and a lithium metal layer plates onto the surface of the current collector. The resulting structure is a protected lithium electrode. To facilitate uniform lithium plating, the electrode precursor may include a "wetting layer" which coats the current collector.
