3D printing, also known as additive manufacturing, has revolutionized how materials are being manufactured with controlled and adaptable spatial geometry. 3D printing is particularly promising for future energy harvesting and storage micro-devices with benefits including versatile shapes, enhanced performance, and the potential to directly integrate power sources into the 3D printed structure and devices. The batteries’ performance is critically determined by the mesoscale structure within the printed electrodes. It is therefore important to understand the non-equilibrium processing steps that determine the mesoscale structure of 3D printed battery materials, with the ultimate goal to control these structures through fine-tuning the highly non-equilibrium processing conditions. 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 structure formation in situ throughout the far-from-equilibrium processing pathways. This work investigates the extrusion-based continuous-flow direct ink writing technique for 3D printing of battery electrodes, with an ultimate goal towards guiding a rational design for the next generation energy storage devices, promising greater impacts on a broader range of technologies in the future.
