Abstract:
Two-dimensional (2D) nanomaterials, such as graphene and transition metal dichalcogenides, hold extraordinary promise for applications in a number of electrochemical technologies. Electrochemical energy storage (EES) devices, such as lithium-ion batteries, flow batteries, and supercapacitors, in particular, have seen 2D materials integrated into various components with exciting results. In general, EES devices are emerging as primary power sources for global efforts to shift energy dependence from limited fossil fuels towards sustainable and renewable resources. These EES devices, while renowned for their high energy or power densities, portability, and long cycle life, are still facing significant performance hindrance due to manufacturing limitations. One major obstacle is the ability to engineer macroscopic components that possess designed and highly resolved microstructures with optimal performance, via controllable and scalable manufacturing techniques. 3D printing covers several additive manufacturing methods that enable well-controlled creation of functional materials with 3D architectures, representing a promising approach for fabrication of next-generation EES devices with high performance. Here, we present recent work to a) develop modeling and optimization algorithms that determine the optimal electrochemical cell geometries for various performance objectives (e.g. maximize current, minimize pressure drop, etc.) and b) fabricate 3D functional electrodes utilizing 3D printing-based methodologies. Specifically, the framework of the 3D printing techniques such as projection microstereolithography and direct ink writing are described, as well as the details of respective feedstock development efforts. Finally, characterization of the 3D-printed electrodes and their performance in various EES applications (e.g. supercapacitors and batteries) will be compared with predicted performance and discussed.
