Abstract: A cabin-interior upright wall of a door inner panel is configured by a first panel member alone. An extension wall extends toward a door outer panel from an end of the cabin-interior upright wall. A lower portion of a front upright wall, which is part of the extension wall, is segmented in a door thickness direction. The extension wall is configured such that a first extension portion of a first panel member is joined to a second extension portion of a second panel member in a state overlapped with the second extension portion.

Abstract: A thin film is used in a metallic collector in order to increase the volume energy density. However, the strength of the thin film is low, so when a negative plate or a positive plate is directly joined to a terminal base portion, even an insignificant load might cause damage, such as cutting of the metallic collector. Even in a structure where the metallic collector is joined to a highly-conductive plate-like metal or a highly-conductive plate-like resin, and where the collecting plate is joined to a terminal base portion, the connection between the collecting plate and the terminal base portion affects the battery properties.

Abstract: A non-aqueous electrolyte secondary battery capable of improving a high rate discharge property while securing safety is provided. A laminated electrode group 10 is sealed in a laminate film of an outer casing in a lithium-ion secondary battery. A positive electrode plate 14 and a negative electrode plate 15 are stacked alternatively in the laminated electrode group 10. In the positive electrode plate 14, a positive electrode mixture layer W2 containing a lithium manganese complex oxide of a positive electrode active material is formed at both surfaces of an aluminum foil W1. In the positive electrode mixture layer W2, other than the positive electrode active material, a carbon material of a conductor and a phosphazene compound of a flame retardant are dispersed and mixed uniformly. A ratio of a mass of the conductor to that of the flame retardant is set to 1.3 or more.
