“…[53] To enhance the materials properties and provide functionalities to the aerogels, it is also possible to use additives in the ink formulations without having a major effect on printability. Accordingly, xyloglucan was proposed as binder for cellulose nanocrystal (CNC), [54] polyamide-epichlorohydrin was used as strength additive for CNC [55] and CNF, [56] carbon nanotube (CNT) was used as a functionalization agent for CNF, [50] lithium iron phosphate and lithium titanium oxide were used as cathode and anode active materials for GO, [57] SnO 2 quantum dots (QDs) were used as electrochemical performance additive for GO, [48] and manganese dioxide nanowires (MONWs), AgNWs, and fullerene was proposed to enhance capacitance, charge delivery, and mechanical properties of Ti 3 C 2 T x -based aerogels (Figure 3e). [58] To extrude the ink from the nozzle, either a pneumatic air pressure, a mechanical piston, or a screw-based deposition system is used.…”

Aerogels are highly porous structures produced by replacing the liquid solvent of a gel with air without causing a collapse in the solid network. Unlike conventional fabrication methods, additive manufacturing (AM) has been applied to fabricate 3D aerogels with customized geometries specific to their applications, designed pore morphologies, multimaterial structures, etc. To date, three major AM technologies (extrusion, inkjet, and stereolithography) followed by a drying process have been proposed to additively manufacture 3D functional aerogels. 3D-printed aerogels and porous scaffolds showed great promise for a variety of applications, including tissue engineering, electrochemical energy storage, controlled drug delivery, sensing, and soft robotics. In this review, the details of steps included in the AM of aerogels and porous scaffolds are discussed, and a general frame is provided for AM of those. Then, the different postprinting processes are addressed to achieve the porosity (after drying); and mechanical strength, functionality, or both (after postdrying thermal or chemical treatments) are provided. Furthermore, the applications of the 3D-printed aerogels/porous scaffolds made from a variety of materials are also highlighted. The review is concluded with the current challenges and an outlook for the next generation of 3D-printed aerogels and porous scaffolds.

“…To optimize the rheology of inks and thereby enhance their electrochemical and mechanical properties, the addition of nanosized materials as fillers has been reported as a promising method. Two‐dimensional layered nanomaterials such as graphene oxide (GO) have been widely used to tune the rheological properties of inks . Compared with polymer‐based and cellulose‐based viscosifiers, GO exhibits higher electrical conductivity after it is converted to reduced graphene oxide (r‐GO) by annealing the printed electrodes .…”

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. This work summarizes the developments in electrochemical devices fabricated by 3D printing techniques. We have categorized this review based on the architectural design of 3D printed EES devices: interdigitated structures, 3D scaffolds, and fibers. The printing techniques, processes, printing materials, advantages, and disadvantages of 3D printed architectures are systematically discussed in this review. Enhanced power density and energy density values were obtained using interdigitated structures and 3D scaffolds, in comparison with the conventional planar structure. The reasons for better electrochemical performances can be attributed to the presence of higher loading active materials, larger footprint area, and shorter ion transport route. The 3D printing techniques have also enabled the EES devices to be fabricated into lightweight, flexible fibers, and to be integrated into wearable electronics. At the end, the challenges and outlooks on the fabrication of 3D structured EES devices are outlined. Figure 1. Schematic summary: the advantages of 3D printing of EES devices with well-designed architecture in better electrochemical performance, higher processing efficiencies, and improved mechanical properties.

“…Zhang et al used DIW to print SnO 2 quantum dot (QD)-based 3D electrodes for LIB. [71] They utilized a sol-gel technique to prepare a monodispersed ink of SnO 2 QD/graphene oxide (GO), and 3D-printed various complex structures. Recently, Gao et al used DIW followed by phase inversion and freeze drying to construct a self-standing electrode for a Li-S battery with high sulfur loading.…”

Superior electrochemical performance, structural stability, facile integration, and versatility are desirable features of electrochemical energy storage devices. The increasing need for high‐power, high‐energy devices has prompted the investigation of manufacturing technologies that can produce structured battery and supercapacitor electrodes with optimized charge transport. While conventional electrode production techniques are becoming increasingly obsolete and incompatible with technological developments such as wearables and flexible electronics, additive manufacturing (AM) has emerged as one of several state‐of‐the‐art tools to produce 3D‐structured electrodes with morphology control, high yield, and scalability. Herein, a comprehensive review of the major AM technologies and most recent literature about designing and manufacturing electrode materials for batteries and supercapacitors is presented. A thorough discussion of research opportunities and challenges in this promising field is also presented to introduce the potential and importance of AM to current developments involving electrode materials.
