“…Nevertheless, octet‐truss electrode shows the smallest R s value as well as the lowest R ct value among them which can be mainly attributed to the largest active surface area and thus the most ions/electrons transfer pathways, consistent with the abovementioned CV and GCD results. In addition, the steep slope of the curve of octet‐truss electrode observed at low frequency indicates a good capacitor characteristic …”

Developing advanced three-dimensional (3D) structural supercapacitors with both high capacity and good mechanical strength remains challenging. Herein, a novel road is reported for fabricating 3D structural strengthening supercapacitors with adjustable capacitance based on urchin-like Cu(OH) 2 lattice electrodes by bridging 3D printing technology with a facile electroless plating and electro-oxidation method. As revealed by the results, the 3D-printed octettruss lattice electrode features a high volumetric capacitance of 8.46 F cm −3 at 5 mA cm −3 and superior retention capacity of 68% at 1 A cm −3 . The assembled symmetric supercapacitor with a 70.2% capacitance retention after 5000 cycles possesses a 12.8 Wh kg −1 energy density at a power density of 2110.2 W kg −1 . Additionally, the resulting 3D structural strengthening electrodes can achieve both high compressive strength and toughness of 30 MPa and 264.7 kJ m −3 , respectively, demonstrating high mechanical strength and excellent antideformation capacity. With the proposed strategy, the electrochemical and mechanical properties of these novel 3D structural strengthened supercapacitors can be easily tuned by a simple spatial framework design, fulfilling the increasing demand of highly customized power sources in the space-constrained microelectronics and astronautic electronics industries.

“…With the high controllability of 3D printing, the width of the gap and thickness of electrolyte can also be adjusted. Compared with the EES devices with traditional sandwich structure, the hierarchical 3D interdigitated electrodes provide large surface area for ion diffusion and offer a pathway for fast electron transfer, resulting in increased efficiency and performance of EES devices …”

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.

Owing to the high power density, long cycle life and maintain‐free, micro‐supercapacitors (MSCs) stand out as preferred miniaturized energy source for the miscellaneous autonomous electronic components. However, the shortage of energy density is the main stumbling block for their practical applications. To solve this energy issue, constructing a three‐dimensional (3D) electrode within the limited footprint area is proposed as a new solution for improving the energy storage capacity of MSCs. In the last few years, extensive efforts have been devoted to developing 3D electrodes for MSCs, and significant progress and breakthrough have been achieved. While, there is still lack of systematic summary on the 3D electrode design strategies. To this end, it is imperative to outline the basic design conception, summarize the current states, and discuss the future research about 3D electrodes in MSCs based on the latest development.
