Abstract: A power storage device includes a pair of holding plates, several ribs and thin-walled portions. The ribs includes first ribs inclined to an extending direction of a first edge and an extending direction of a second edge and extending along straight lines connecting first engaging portions and second engaging portions, and second ribs extending along a facing direction in which the first edge and the second edge face each other. At least first ribs extend in different directions from each other and form an intersection where the at least two first ribs intersect with each other. At least one of the second ribs has opposite ends connected to the first ribs intersecting with each other.

Abstract: Electrochemical devices, and associated materials and methods, are generally described. In some embodiments, an electrochemical device comprises an electroactive material. The electroactive material may comprise an alloy having a solid phase and a liquid phase that co-exist with each other. As a result, such a composite electrode may have, in some cases, the mechanical softness to permit both high energy densities and an improved current density as compared to, for example, a substantially pure metal electrode.

Abstract: An alloy anode for a seawater based aqueous battery and a universal strategy for preparing anodes for use in seawater based aqueous batteries. Zn-M alloys (where M can be manganese or other transition metal) were prepared by co-electrodeposition in the presence of hydrogen bubble formation to produce a porous nanostructured alloy that can serve as an anode for a seawater based aqueous battery. Exemplary Zn—Mn alloy anodes achieved stability over thousands of cycles even under harsh electrochemical conditions, including testing in seawater-based aqueous electrolytes and using a high current density of 80 mA cm−2. The anode design strategy allows for the production of durable electrodes for aqueous batteries and other applications.
