What is a 3D electrode architecture?
By contrast, a 3D electrode architecture contains a 3D conductive scaffold acting as a 3D current collector and a 3D porous network for efficient ion transport.
What are the architectural designs of 3D printed electrochemical energy storage devices?
Architectural aesthetics: In this review, the architectural designs of 3D printed electrochemical energy storage (EES) devices are categorized into interdigitated structures, 3D scaffolds, and fibers. The 3D printing techniques, processes, printing materials, and performances of 3D printed EES devices architectures are systematically discussed.
Is three-dimensional (3D) printing the future of electrochemical energy storage?
Recently, the fabrication of electrochemical energy storage (EES) devices via three-dimensional (3D) printing has drawn considerable interest due to the enhanced electrochemical performances that arise from well-designed EES device architectures as compared to the conventionally fabricated ones.
Can a 3D printed electrode reduce power losses?
This structure was then 3D printed using a PuSL system and pyrolyzed. The electrode was then electrochemically tested and compared to control electrodes of homogeneous porosity. We demonstrated that the optimized electrode reduced power losses by 16% at the operating current and flow rate it was specifically designed for.
Are 3D electrodes better than planar electrodes?
Compared with planar electrodes, 3D electrodes ensure more efficient charge delivery and better utilization of electrode material in thick electrodes (for example, >100 μm) with practical levels of mass loading (for example, >10 mg cm −2) (Fig. 2c,d).
Does 3D architecture affect the performance of porous electrodes?
This is especially true for porous electrodes, where the performance is known to be strongly affected by its 3D architecture across the nano-, micro- and meso- length scales 7. Properly defining these relationships can be obscured by a lack of control over the electrode structure itself, which is often disordered.
