20110076558 | NON-AQUEOUS ELECTROLYTE SECONDARY CELL - The present invention provides a non-aqueous electrolyte secondary cell that has high voltage, high capacity and excellent high-temperature cycle characteristics at a low cost. | 03-31-2011 |
20110177364 | NONAQUEOUS ELECTROLYTE SECONDARY BATTERY - Provided is a nonaqueous electrolyte secondary battery using lithium-manganese composite oxide as positive electrode active material, having superior high-temperature charge storage characteristics and charge-discharge cycling characteristics and enhanced safety in the event of overcharging. A nonaqueous electrolyte secondary battery according to an aspect of the invention includes: a positive electrode plate provided with a positive electrode mixture containing positive electrode active material, a negative electrode plate, a nonaqueous electrolyte, and a pressure-sensitive safety mechanism that is actuated by rise in internal pressure. The positive electrode active material contains lithium-manganese composite oxide containing 10 to 61% by mass of the element manganese. The positive electrode mixture contains lithium carbonate or calcium carbonate, and lithium phosphate. The nonaqueous electrolyte contains an organic additive made of at least one selected from among biphenyl, a cycloalkyl benzene compound, and a compound having quaternary carbon adjacent to a benzene ring. | 07-21-2011 |

20130004827 | NONAQUEOUS ELECTROLYTE SECONDARY BATTERY - Provided is a nonaqueous electrolyte secondary battery. The stacked electrode assembly contains positive electrode plates in which no positive electrode active material layer is formed on at least one side of the positive electrode substrate and negative electrode plates in which no negative electrode active material layer is formed on at least one side of the negative electrode substrate. Such positive electrode surfaces where no positive electrode active material layer is formed are opposed, with a separator interposed, to such negative electrode surfaces where no negative electrode active material layer is formed. The separator interposed between the positive electrode active material layers and negative electrode active material layers has a layer containing ceramic. The separator interposed between the surfaces where no positive electrode active material layer is formed and the surfaces where no negative electrode active material layer is formed has no layer containing ceramic. | 01-03-2013 |
20130052510 | NON-AQUEOUS ELECTROLYTE SECONDARY-CELL BATTERY AND MANUFACTURING METHOD - To improve cycling characteristics by evening out the battery reaction across different areas of a laminated electrode assembly in a non-aqueous electrolyte secondary-cell battery where the laminated electrode assembly, having tape applied to a top layer, an end face, and a bottom layer thereof, is contained in an outer casing, the tape applied to the periphery of the laminated electrode assembly, configured from a stacked plurality of interleaved separators, cathode plates, and anode plates, extends in the stacking direction across the top layer, end face, and bottom layer of the laminated electrode assembly. Each piece of tape is formed of a base material that is one of styrene-butadiene rubber, styrene rubber, or butadiene rubber. | 02-28-2013 |
