| Abstract Scope |
This talk introduces multiscale-controlled electrodes for lithium-ion batteries. First, a hybrid electrode structure was fabricated by a 3D printed extrusion process, where hybrid means to combine the benefits of conventional laminated structure and 3D interdigitated structure. Then, an idea of self-assembly of particles via an electric field process along with 3D printed structures based on additive manufacturing proved the important roles of micro/macrostructure on battery performance. This synergistic control of micro-/macro-structures is a novel concept in energy material processing and has considerable potential for providing unprecedented control of electrode structures with enhancing performance. In addition, thin coated active particles through atomic layer deposition (ALD) have been integrated with a 3D electrode structure to achieve further performance. The nanoscale coating/doping provided enhanced fundamental properties, including transport and structural properties, while the mesoscale control could provide a better network of the nanostructured elements by decreasing the diffusion path between. |
