High surface area metals are utilized as battery anodes and capacitor electrodes. New metal and metal alloys need development to improve capacitor and battery capabilities. Nanocellular metal alloy materials attract much research interest for anode material due to their tunable chemical resistivity and high specific mechanical properties. In this presentation, the scale-up synthesis and mechanical properties of a nickel nanocellular metal were investigated. Nanocellular metal/metal alloy was prepared with nanomaterials via a wet chemistry process followed by heat treatment to produce a 3D framework. The process scale-up of 200x did not affect the diameter of the metal ligament and crystal phase based on SEM images, neutron scattering and XRD. The robustness of the process was investigated with respect to temperature and precursor concentrations to understand if growth rate or nucleation would significantly impact the ligament diameters. The elastic modulus and loss modulus were then investigated using nanoindentation to determine the mechanical properties of interest. These results indicate that a reliable anodic material can be synthesized from nanowires using the presented wet chemistry technique.
