Abstract: An electrode for the use of an advanced lithium battery is fabricated using three-dimensionally structured metal foam coated with an active material. The metal foam is porous metal foam that can be used as an anode current collector of a lithium-ion battery and is coated with an anode active material, such as tin, through a sonication-assisted electroless plating method. Additionally, the coated metal foam is heat-treated at an appropriate temperature in order to improve the integrity of the coating layer and hence, the cyclic performance of the lithium-ion battery.

Abstract: An innovative fuel cell system with MEAs includes a polymer electrolyte membrane, a gas diffusion layer (GDL) made of porous metal foam, and a catalyst layer. A fuel cell has a metal foam layer that improves efficiency and lifetime of the conventional gas diffusion layer, which consists of both gas diffusion barrier (GDB) and microporous layer (MPL). This metal foam GDL enables consistent maintenance of the suitable structure and even distribution of pores during the operation. Due to the combination of mechanical and physical properties of metallic foam, the fuel cell is not deformed by external physical strain. Among many other processing methods of open-cell metal foams, ice-templating provides a cheap, easy processing route suitable for mass production. Furthermore, it provides well-aligned and long channel pores, which improve gas and water flow during the operation of the fuel cell.

Abstract: A dye-sensitized solar cell has a working electrode, electrolyte, and counter electrode. The counter electrode includes a nickel (Ni) foam, titanium (Ti) foam, manganese (Mn) foam, or molybdenum (Mo) foam, and has a surface that is nitrided. The reaction efficiency for the solar cell is enhanced by the increased surface area reacting with the electrolyte, which results from using a metal foam. Mechanical properties, such as strength and ductility, and electroconductivity are improved due to the use of metals. The production costs are reduced by using substitute materials, which are low-cost and have oxidation-reduction efficiency.
