Abstract: A battery module includes a battery stack having a plurality of batteries that are stacked and a heat transfer suppression member disposed between adjacent two of the batteries, a heat conductor that extends in stacking direction X of the batteries and is adjacent to the battery stack, and a heat absorber that intervenes between the battery stack and the heat conductor and contains an endothermic agent that is to start endothermic reaction at a temperature higher than or equal to a predetermined temperature.

Abstract: A battery module includes a battery stack having a plurality of stacked batteries, a first heat radiator facing first surface of battery stack, a first heat transfer component that is in contact with the first heat radiator and first surface to transfer heat from the battery stack to the first heat radiator, and a second heat radiator facing a second surface of the battery stack. The second surface extends in a direction intersecting with the first surface. The second heat radiator is thermally connected to the second surface directly or through the second heat transfer component. A positional relationship between the first heat transfer component and the battery stack is formed such that the center of the first heat transfer component (84) is more away from the second heat radiator than the center of the battery stack is in a direction along the first surface.

Abstract: Each secondary battery cell includes: an exterior can that has a rectangular outer shape having a thickness smaller than the width and has an open upper surface; a sealing plate for blocking the opening of the exterior can; a pair of electrode terminals disposed on the sealing plate; a conductive reversing plate that is disposed on the sealing plate, and becomes deformed when the internal pressure of secondary battery cell becomes a predetermined value or more; and connection plate that is disposed on the sealing plate and on the outer surface side of secondary battery cell, and, when the reversing plate becomes deformed, contacts and electrically connects to the reversing plate to block an external output. Fastening member is disposed on the upper surface of the cell stacked body so as to overlap the position at which the reversing plate is disposed on the upper surface of the sealing plate of each secondary battery cell.

Abstract: An object is to reduce the overall height and outside dimensions of a secondary battery. Another object is to prevent the secondary battery from being damaged by nut tightening torque. A secondary battery includes an electrode body (15), an outer can (11), a sealing plate (12), a pair of electrode terminals (13), and a short-circuit mechanism (20). The pair of electrode terminals (13) includes a first electrode terminal (13A) and a second electrode terminal (13B). The short-circuit mechanism (20) includes a conductive reversible plate (22) secured to the sealing plate (12), and a reversible plate receiver (25) disposed opposite the reversible plate (22). The reversible plate receiver (25) includes a first output terminal (31), and the first output terminal (31) is electrically insulated from the sealing plate (12). The first output terminal is electrically connected to the first electrode terminal, and is spaced from the first electrode terminal.

Abstract: A secondary battery includes an electrode body, an outer can, a sealing plate, electrode terminals, and a current interrupt device. The electrode terminals includes a first electrode terminal and a second electrode terminal, and are electrically connected to the electrode body through a collector member. The current interrupt device includes a short-circuit part that short-circuits the battery when the internal pressure exceeds a set pressure, and a fuse part disposed in the collector member. The fuse part is disposed close to an upper end corner portion serving as a boundary portion between an upper surface and a side surface of the secondary battery. A binding member includes a protective cover portion that covers the upper end corner portion of the secondary battery, and the protective cover portion includes an upper-surface covering part and a side-surface covering part.

Abstract: An antenna manufacturing method including the step of inputting as variables shape of a case, position of an antenna in the case, shape of the antenna, position of antenna peripheral components in the case, and shape of the antenna peripheral components, and the step of computing optimum value of the variables by a simulation program. With this manufacturing method, radiation efficiency of the antenna and the communications device that uses it can be enhanced.
