“…Direct ink writing (DIW) is one of the most commonly used 3D‐printing techniques. It offers great flexibility in the material (ink) selection and has been recently applied to prepare electrodes for electrochemical energy storage devices, including lithium‐ion batteries, sodium‐ion batteries, lithium–sulfur batteries, lithium metal batteries, and supercapacitors . In comparison to bulk electrodes, these 3D‐printed electrodes have shown improved electrolyte infiltration and ion diffusion …”

3D‐Printed Structure Boosts the Kinetics and Intrinsic Capacitance of Pseudocapacitive Graphene Aerogels

The performance of pseudocapacitive electrodes at fast charging rates are typically limited by the slow kinetics of Faradaic reactions and sluggish ion diffusion in the bulk structure. This is particularly problematic for thick electrodes and electrodes highly loaded with active materials. Here, a surface‐functionalized 3D‐printed graphene aerogel (SF‐3D GA) is presented that achieves not only a benchmark areal capacitance of 2195 mF cm−2 at a high current density of 100 mA cm−2 but also an ultrahigh intrinsic capacitance of 309.1 µF cm−2 even at a high mass loading of 12.8 mg cm−2. Importantly, the kinetic analysis reveals that the capacitance of SF‐3D GA electrode is primarily (93.3%) contributed from fast kinetic processes. This is because the 3D‐printed electrode has an open structure that ensures excellent coverage of functional groups on carbon surface and facilitates the ion accessibility of these surface functional groups even at high current densities and large mass loading/electrode thickness. An asymmetric device assembled with SF‐3D GA as anode and 3D‐printed GA decorated with MnO2 as cathode achieves a remarkable energy density of 0.65 mWh cm−2 at an ultrahigh power density of 164.5 mW cm−2, outperforming carbon‐based supercapacitors operated at the same power density.

“…Another method for enhancing the energy density and areal capacitance is to fabricate thicker electrodes that can significantly raise the active material loading while preserving rapid ion diffusion . With increasing electrode thickness, however, the electron transport distances and overall electrical impedance of the electrode will inevitably increase, resulting in reductions of power density and rate capability . Compared with conventional 2D planar structures, 3D structures can yield shorter diffusion pathways and lower resistance during the ion‐transport process, as well as providing increased energy density by creating porous structures with larger surface areas that can improve electrode reaction and ion transfer while efficiently using the limited space in a compact battery .…”

Additive manufacturing, i.e., 3D printing, is being increasingly utilized to fabricate a variety of complex-shaped electronics and energy devices (e.g., batteries, supercapacitors, and solar cells) due to its excellent process flexibility, good geometry controllability, as well as cost and material waste reduction. In this review, the recent advances in 3D printing of emerging batteries are emphasized and discussed. The recent progress in fabricating 3D-printed batteries through the major 3D-printing methods, including lithographybased 3D printing, template-assisted electrodeposition-based 3D printing, inkjet printing, direct ink writing, fused deposition modeling, and aerosol jet printing, are first summarized. Then, the significant achievements made in the development and printing of battery electrodes and electrolytes are highlighted. Finally, major challenges are discussed and potential research frontiers in developing 3D-printed batteries are proposed. It is expected that with the continuous development of printing techniques and materials, 3D-printed batteries with long-term durability, favorable safety as well as high energy and power density will eventually be widely used in many fields.

Ceramic is a typical brittle‐essence material, which makes the low strength a fatal problem for ultra‐light ceramic lattices with ultra‐high porosity. In this study, ultra‐light ceramic lattices with calculated density of ca. 0.8 g/cm3 and porosity up to ca. 80% reaching maximum compressive strength of 107 MPa were successfully printed by a three‐dimensional (3D) printing technology stereolithography. Ultra‐high‐specific strength of the printed ceramic lattices (32 N·m/g) was even much higher than that of the steel lattices (2 N·m/g) (Int J Mach Tool Manuf, 62, 2012, 32). Short‐cut quartz fibers and in situ growing Si3N4 whiskers were introduced as reinforcements to improve the strength of the printed lattices. Compressive strengths of the ceramic lattices improved by 2.8 and 3.6 times stronger than the originals, respectively. Significantly, energy absorption of the ceramic lattices under compression reached over 10 times larger than before. In comparison with the originals, micronano reinforcements significantly improved the compressive properties of the lattices with microsupporting structures and network formed in internal pores while maintaining the ultra‐light structure.
