    摘要： A rechargeable battery includes an iron electrode comprising carbonyl iron composition dispersed over a fibrous electrically conductive substrate. The carbonyl iron composition includes carbonyl iron and at least one additive. A counter-electrode is spaced from the iron electrode. An electrolyte is in contact with the iron electrode and the counter-electrode such that during discharge. Iron in the iron electrode is oxidized with reduction occurring at the counter-electrode such that an electric potential develops. During charging, iron oxides and hydroxides in the iron electrode are reduced with oxidation occurring at the counter-electrode (i.e., a nickel electrode or an air electrode).

    摘要： A secondary battery according to an embodiment includes a container, an electrolytic solution, a cathode and an anode, and a flow mechanism. The container includes an opening on a bottom surface thereof. The electrolytic solution is disposed in the container. The cathode and the anode are disposed in the electrolytic solution. The flow mechanism includes a generation part that is connected to the container via the opening and generates a gas bubble(s) in the container through the opening, and that causes the electrolytic solution to flow. A protrusion part that is positioned at an edge part of the opening and extends in upward and downward directions is disposed on the bottom surface.

    摘要： There is disclosed an electrode cartridge for use in a hermetic zinc secondary battery comprising a separator structure including a separator exhibiting hydroxide ion conductivity and water impermeability; a counter member liquid-tightly sealed to the separator structure so as to form an internal space and constituting an open-top water impermeable case together with the separator structure; and an electrode that is accommodated in the internal space of the water impermeable case and is a negative electrode containing zinc and/or zinc oxide or a positive electrode. According to the present invention, there is provided an electrode built-in component that can reliably isolate the positive and negative electrodes from each other with a hydroxide ion conductive separator, in the form of an electrode cartridge that is easy to handle and manufacture and that is more advantageous for assembling a stacked-cell battery, while reducing the number of sealing joints.

    摘要： The present invention provides a sequential and efficient method of assembling a battery with a desired number of layers while reliably separating positive and negative electrode sides from each other with one or more separator structures. According to the invention, the method of assembling a battery includes stacking one or multiple combinations each comprising a frame and a positive electrode plate to be disposed in a region defined by the frame and one or multiple combinations each comprising a frame and a negative electrode plate to be disposed in a region defined by the frame, once or alternately, such that the positive and adjacent negative electrode plates are separated from each other by a separator structure and the periphery of the separator structure is held between the adjacent frames. The separator structure includes a separator exhibiting hydroxide ion conductivity and water impermeability.
