摘要： The present invention provides a novel composition and method for preventing decomposition of one or more electrochemical cell components comprising an electrode having an active material, and an electrolyte. The method of the invention, for the first time, effectively overcomes problems which arise between the interaction of cell components and contaminate water retained in a cell. Such contaminate water reacts with the electrolyte which comprises a salt of lithium in a solvent. Solubilizing of the salt in solution with attendant interaction between the salt and water causes formation of hydrogen-containing acids. The method of the invention effectively blocks decomposition of a lithium metal oxide cathode active material, and particularly lithium manganese oxide (LMO, nominally LiMn.sub.2 O.sub.4). Such decomposition is prevented by including in the cell a basic compound which forms an electron donor species in the electrolyte solution; and by neutralizing at least a portion of the acid by reacting the donor species with the hydrogen-containing acids thereby preventing decomposition of the lithium manganese oxide by the acid. The preservation of the lithium manganese oxide prevents degradation of other cell components by other mechanism. The basic compound is desirably an organic base, preferably a butylamine.

摘要： The invention provides an electrochemical cell having an electrolyte which comprises a solute, a solvent, and an additive. The additive is a dialkylamide. The dialkylamide lessens the extent of decomposition of the solute, which is a lithium salt. The ionic species of the lithium salt are thereby preserved. The additive also prevents damage to active material by absorbing excess charge energy below the breakdown potential of the active material.

摘要： The invention provides a new family of compounds and a method of making the compounds. The new compounds are useful as ion conductive salts, and particularly useful as salts for batteries. The compounds of the invention are prepared from three principal reagents, bis (trifluoromethanesufonyl) methane (CF.sub.3 SO.sub.2).sub.2 CH.sub.2 ; benzoyl chloride; and pyridine which facilitates reaction and then is removed. A precursor sodium salt (CF.sub.3 SO.sub.2).sub.2 CHNa is first prepared. Then, equimolar amounts of the precursor sodium salt and pyridine are dissolved in anhydrous acetonitrile. A stoichiometric amount of the selected substitute benzoyl chloride is then added drop by drop. After addition of Li.sub.3 PO.sub.4, there is pyridine release and formation of the product of the aforesaid two reagents. In the benzene ring, R.sub.1, R.sub.2, R.sub.3, R.sub.4, and R.sub.5 are each identical or different and are each independently selected from hydrogen and an electron withdrawing substituent.

摘要： The subject invention discloses a novel method of providing a binary electrolyte-solvent solution in a solid battery system. A first component of this binary electrolyte solvent system is provided by a material which acts as a plasticizer in the formation of a solid polymeric matrix (separator), composite cathode and/or composite anode, and which also acts as an electrolyte solvent in the completed electrochemical cell. The second component of the binary electrolyte solvent system is an electrolyte solvent, which generally carries the electrolyte salt into the electrolytic cell precursor. The first and second components of the binary electrolyte solvent system mix within the electrolytic cell, dispersing the electrolyte salt throughout the binary electrolyte solvent system. The addition of the electrolyte salt to the electrolytic cell precursor acts to activate the cell precursor, and to form a functional electrolytic cell or battery system.
