  • Publication number: 20130048901
    Abstract: A method of forming an electrolyte solution involves combining ammonium tetrafluoroborate and a quaternary ammonium halide in a liquid solvent to form a quaternary ammonium tetrafluoroborate and an ammonium halide. The ammonium halide precipitate is removed from the solvent to form an electrolyte solution. The reactants can be added step-wise to the solvent, and the method can include using a stoichiometric excess of the ammonium tetrafluoroborate to form a substantially halide ion-free electrolyte solution. Filtration can be done at low temperatures to reduce the amount of excess bromide in the resulting electrolyte.

The cell contains electrodes (e.g., two electrodes) that each contain a porous matrix of electrochemically-active particles (e.g., carbon). An aqueous-based electrolyte is disposed in contact with the porous matrix.

Because the polymer is anionic in nature, it is generally hydrophilic and thus can retain its binding properties in the presence of water. The anionic nature of the polymer also allows it to remain stable in the presence of a corrosive polyprotic acid, which is employed in the electrolyte to enhance charge density.

  • Patent number: 8277972
    Abstract: A non-aqueous electrolyte solution for a lithium secondary battery includes a lithium salt and a carbonate organic solvent. The non-aqueous electrolyte solution further includes a fluoro group-containing sulphonate compound expressed by Chemical Formula 1. When the non-aqueous electrolyte solution is employed for a lithium secondary battery, low-temperature discharging characteristics and life cycle characteristics are greatly improved. Also, even though a battery is stored at a high temperature in a fully-charged state or a charging/discharging process is under progress, the decomposition reaction of a carbonate-based organic solvent is restrained, thereby solving the swelling problem and improving high-temperature life cycle characteristics.
