Abstract Scope |
Additive manufacturing methods such as printing allows the fabrication of microstructures with rapid changes to design, use of a large number of functional materials, and novel device geometries. In this research, we develop a fabrication technique using printed electronics to create a new class of three-dimensional (3D) micro-architected materials without any support materials. The printed structures are then used to enhance the performance of energy storage devices. Microlattice electrodes with porous solid truss members are fabricated that leads to a significant improvement in the battery performance in terms of specific capacity and areal capacity when compared to a thin solid block electrode. These results indicate that the 3D printed structures enhance electrolyte transport through the electrode volume, increase the available surface area for electrochemical reaction, and relieve the intercalation-induced stress. Other 3D printed functional devices are also demonstrated. |
