20100068629 | ALKALI METAL SEAWATER BATTERY - A galvanic cell is disclosed. Generally, the cell includes an alkali metal anode, which electrochemcially oxidizes to release alkali metal ions, and a cathode, which is configured to be exposed to an electrolyte solution. A water-impermeable, alkali-ion-conductive ceramic membrane separates the anode from the cathode. Moreover, an alkali-ion-permeable anode current collector is placed in electrical communication with the anode. In some cases, to keep the anode in contact with the current collector as the cell functions and as the anode is depleted, the cell includes a biasing member that urges the anode against the current collector. To produce electricity, the galvanic cell is exposed to an aqueous electrolyte solution, such as seawater, brine, saltwater, etc. | 03-18-2010 |
20100178569 | ELECTROLYTE AND SECONDARY BATTERY - An electrolyte includes a solvent and an electrolyte salt. The solvent contains at least one selected from ester compounds, lithium monofluorophosphate, and lithium difluorophosphate, and at least one selected from anhydrous compounds. The ester compounds are chain compounds having ester moieties, such as (—O—C(═O)—O—R), at both ends. The anhydrous compounds are cyclic compounds having, for example, a disulfonic anhydride group, (—S(O═) | 07-15-2010 |
20110008680 | HIGH VOLTAGE ELECTROLYTE - An organic electrolyte solvent includes a compound of the formula: R | 01-13-2011 |
20110070504 | SECONDARY BATTERY - This invention relates to a highly safe secondary battery. In the secondary battery of this invention, a positive electrode is formed of an oxide which adsorbs/desorbs lithium ions; a negative electrode is formed of a carbon material which adsorbs/desorbs lithium ions; and an electrolyte solution is formed of an ion liquid and a phosphoric acid ester derivative. Consequently, the secondary battery can be highly safe. Since a phosphate ester and an ion liquid are contained at the same time, high discharge capacity can be maintained even when the phosphate ester is used at a high concentration. | 03-24-2011 |
