    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: A lithium secondary battery of the present invention has a positive electrode is provided with a positive electrode mix layer that includes a positive electrode active material and a conductive material. The positive electrode mix layer has two peaks, large and small, of differential pore volume over a pore size ranging from 0.01 μm to 10 μm in a pore distribution curve measured by a mercury porosimeter. A pore size of the smaller peak B of the differential pore volume is smaller than a pore size of the larger peak A of the differential pore volume.
