  • Salts of alkali metals of N, N? disubstituted amides of alkane sulfinic acid and nonaqueous electrolytes on their basis
    Patent number: 6858346
    Abstract: An organic salt having an alkali metal bound to a disubstituted amide of alkane iminosulfinic acid has the following general formula: where Ar is an aromatic group, M is an alkali metal such as Li, K or Na, and CxHy is an alkane. The organic salt can be used to form non-aqueous liquid and gel or plasticized polymer electrolytes. The electrolytes can be used to form improved lithium and lithium ion batteries.

  • Nonaqueous electrolytes based on organosilicon ammonium derivatives for high-energy power sources
    Patent number: 6803152
    Abstract: A nonaqueous electrolyte additive includes an organosilicon backbone including at least one ethylene oxide (CH2CH2O) unit, at least two pyridinium groups bound to the backbone, the pyridinium groups each bound to at least one halogen ion or halogen-containing anion. The additive is useful for forming improved liquid and polymer electrolytes for lithium ion and lithium metal batteries.

  • Solid polymer electrolyte lithium battery
    Publication number: 20030031933
    Abstract: A polymer electrolyte includes a modified polymeric material, the modified polymeric material including a halogen containing polymer having an enhanced halogen level, the enhanced halogen level relative to a halogen content of the halogen containing polymer formed from polymerization of its monomer. A salt of an alkali metal and an aprotic solvent are also provided. The salt and the aprotic solvent are integrated with the modified polymeric material. The halogen containing polymer is preferably polyvinylchloride (PVC) obtained by emulsion or suspension polymerization of vinylchloride. A method for preparing solid polymer electrolytes includes the steps of providing a halogen containing polymer, halogenating the halogen containing polymer, wherein an enhanced halogen containing modified polymer material results. The enhanced halogen level is relative to the halogen content of the halogen containing polymer formed from polymerization of its monomer.
