Abstract Scope |
3D printing, or additive manufacturing, is a promising technique for designing energy storage micro-devices, with benefits including versatile shape and geometry, new architectural design, and the potential to directly integrate power sources into the 3D printed devices. As the mesoscale structure within the printed electrodes directly determine the physical and chemical properties of the printed materials, understanding the dynamics during the printing process and the post-printed battery microstructure is thus of critical importance. In this work, we utilized operando synchrotron coherent X-ray scattering techniques, including X-ray photon correlation spectroscopy (XPCS), to study the dynamics of mesoscale structural formation throughout the far-from-equilibrium processing pathways. We also utilized synchrotron X-ray nano-tomography to reveal the printed 3D structure. This work investigates the extrusion-based direct ink writing technique, with a goal towards guiding a rational design of the next generation energy storage devices, especially for environmentally friendly systems such as 3D printable aqueous batteries. |
