    摘要： A non-aqueous electrolyte secondary cell superior in safety against overcharge and in high-temperature cycle characteristic is provided. The non-aqueous electrolyte secondary cell includes a positive electrode, a negative electrode, a non-aqueous electrolyte, and a pressure sensitive safety mechanism that is actuated upon increase in the cell internal pressure. The positive electrode contains lithium carbonate at 0.5 to 1.5 mass %. The non-aqueous electrolyte contains a cycloalkyl benzene compound and/or a compound having a benzene ring and a quaternary carbon adjacent to the benzene ring, the compound or compounds being contained at 0.5 to 2 mass % in total.

    摘要： An electrode assembly of an alkaline secondary battery includes positive and negative electrodes disposed to face each other via a separator sandwiched therebetween. The separator has a dual-layer structure composed of a main-fiber nonwoven layer and an aromatic-polyamide-fiber nonwoven layer that are laminated in the thickness direction. The main-fiber nonwoven layer contains nylon as main fiber and does not contain aromatic-polyamide-fiber. In the electrode assembly, the separator is so disposed that the aromatic-polyamide-fiber nonwoven fabric layer faces toward the negative electrode.
