    摘要: The present invention relates to non-aqueous electrolytes having stabilization additives and electrochemical devices containing the same. Thus the present invention provides electrolytes containing an alkali metal salt, a polar aprotic solvent, a first additive that is a substituted or unsubstituted organoamine, substituted or unsubstituted alkane, substituted or unsubstituted alkene, or substituted or unsubstituted aryl compound, and/or a second additive that is a metal (chelato)borate. When used in electrochemical devices with, e.g., lithium manganese oxide spinel electrodes, the new electrolytes provide batteries with improved calendar and cycle life.

    摘要: Fast-cure gel polymer electrolytes are prepared by trapping an oligo(alkylene glycol)siloxane or silane in a three dimensional polymer matrix. An ion-conducting phase of the electrolyte contains a siloxane or silane compound and a lithium salt. Such siloxanes or silanes include a silicon or silicon oxide group having four or less substituents that is an oligo(alkylene glycol), or cyclic carbonate moiety.
