Background
Nanoporous metals, especially copper, are critical in fields like hydrogen production, battery technology, and energy storage due to their high surface area and conductivity. However, traditional sintering methods require high temperatures, which often reduce porosity and compromise performance. Additionally, the mechanical instability of nanoporous metals limits their integration into large-scale manufacturing.
Invention Description
Researchers at Arizona State University have developed a novel method for fabricating high surface area electrodes using copper nanoporous powders. These powders are created through a dealloying process, resulting in a porous copper structure with an exceptionally large surface area, ideal for energy applications. To address the limitations of traditional high-temperature sintering, the process incorporates copper nanoparticles, enabling sintering at much lower temperatures. This preserves the nano porosity and enhances the mechanical and electrical properties of the material, making it more suitable for energy-intensive applications like hydrogen electrolysis and battery technologies.
The method is also compatible with powder-based manufacturing, allowing for the scalable production of complex 3D components. These high-performance electrodes are ideal for use in industries requiring advanced energy storage and conversion, such as hydrogen production, batteries, and energy storage systems. By maintaining the structural integrity of nanoporous copper at lower temperatures, this innovation paves the way for more efficient, durable, and scalable solutions across multiple energy sectors.
