摘要： Provided are electrochemical cells and electrolytes used to build such cells. The electrolytes include imide salts and/or methide salts as well as fluorinated solvents capable of maintaining single phase solutions at between about −30° C. to about 80° C. The fluorinated solvents, such as fluorinated carbonates, fluorinated esters, and fluorinated esters, are less flammable than their non-fluorinated counterparts and improve safety characteristics of cells containing these solvents. The amount of fluorinated solvents in electrolytes may be between about 30% and 80% by weight not accounting weight of the salts. Linear and cyclic imide salts, such as LiN(SO2CF2CF3)2, and LiN(SO2CF3)2, as well as methide salts, such as LiC(SO2CF3)3 and LiC(SO2CF2CF3)3, may be used in these electrolytes. Fluorinated alkyl groups enhance solubility of these salts in the fluorinated solvents. In some embodiments, the electrolyte may also include a flame retardant, such as a phosphazene, and/or one or more ionic liquids.

摘要： Provided are electrochemical cells and electrolytes used to build such cells. An electrolyte includes at least one salt having a molecular weight less than about 250. Such salts allow forming electrolytes with higher salt concentrations and ensure high conductivity and ion transport in these electrolytes. The low molecular weight salt may have a concentration of at least about 0.5M and may be combined with one or more other salts, such as linear and cyclic imide salts and/or methide salts. The concentration of these additional salts may be less than that of the low molecular weight salt, in some embodiments, twice less. The additional salts may have a molecular weight greater than about 250. The electrolyte may also include one or more fluorinated solvents and may be capable of maintaining single phase solutions at between about −30° C. to about 80° C.

摘要： Provided are electrochemical cell assemblies and methods of fabricating thereof. A cell assembly includes an anode containing lithium titanium oxide and a cathode forming a jellyroll together with the anode. Each of the electrodes is connected to a separate cap and electrically insulated from the case. As such, the case is electrochemically neutral and may be made from a larger selection of materials. For example, a case may be made from steel that would otherwise dissolve if exposed to the anode potential during cycling of the battery. Some of these case materials simplify processing and sealing characteristics. In certain embodiments, a case may be crimped around each of the caps and corresponding gaskets to provide sealing interfaces. The caps or at least their surfaces exposed to the electrolyte are made from materials that are electrochemically stable at corresponding potentials of the electrodes.
