摘要： The present invention provides a method of protecting against damage from overcharge in a rechargeable battery. The method is characterized as including the steps of providing a lithium sulfur battery which has a negative electrode and a sulfur positive electrode. The sulfur positive electrode includes active sulfur, an electronic conductor mixed with the active sulfur so that electrons can move between the active sulfur and an electronic conductor, and an ionic conductor mixed with the active sulfur so that ions can move between the ionic conductor and the active sulfur. The battery made from these materials is subjected to overcharge that is not substantially higher than the normal voltage of the cell, wherein the sulfur positive electrode has between about 10 to 100 % active sulfur available for the electrochemical reaction which prevents the rechargeable battery from damage due to overcharge.

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 (16) between a lithium ion conductive protective layer (18) and a current collector (14) 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.
