    摘要： The present invention provides a sealed lithium secondary battery in which redox shuttle reactions of an aromatic compound that is an overcharge inhibitor are inhibited, and the aromatic compound decomposes appropriately, and a desired amount of gas can be generated more stably than in conventional instances, even in high-temperature environments. In the sealed lithium secondary battery (100), an electrode assembly (80) and an electrolyte are accommodated in a battery case (50) that is provided with a current interrupt device (30). The electrolyte comprises a compound that is capable of suppressing drops in viscosity of the electrolyte as a result of a rise in temperature in a temperature region up to 100° C., and an aromatic compound capable of generating hydrogen gas when a predetermined battery voltage is exceeded.

    摘要： This invention provides a lithium secondary battery that comprises a positive electrode comprising a positive electrode active material layer and a negative electrode comprising a negative electrode active material layer. The positive electrode active material layer and the negative electrode active material layer are placed to face each other. The negative electrode active material layer has an area A comprising a non-positive-electrode-facing portion that does not face the positive electrode active material layer. The area A comprises a negative electrode active material, a hot-melt binder and a temperature-sensitive thickener. The hot-melt binder has a melting point and the temperature-sensitive thickener has a gelation temperature both in a range of 45° C. to 100° C.
