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.

Recent reviews on LBs have provided a good overview of the developments of high energy density LBs based on diverse battery chemistries. [3][4][5][6] It is believed that the energy density of current LBs can be improved up to 300-350 Wh kg −1 in a short time by using high-nickel (Ni) content cathodes, silicon (Si) dominant anodes, and higher voltage electrolytes, but further progress is needed to achieve an acceptable lifetime for practical application. [7] In regards to long term goals, continued research and development (R&D) of next-generation LBs is necessary to meet the Battery500 Project target of a cell-level specific energy of 500 Wh kg −1 , [8] which necessitates a combination of both innovative battery chemistries (such as lithium (Li)-sulfur (S), Li-O 2 , Li-CO 2 , and so on), and cell configurations (improved active material ratio and cell integration). [9] However, the majority of current research efforts are dedicated to the R&D of battery materials while battery configurational design is relatively overlooked. Interestingly, with the progress in the development of water-in-salt electrolyte and the corresponding battery chemistry, aqueous LIBs are also possible to meet the Battery 500 Project target. A representative work is the aqueous LIBs that has been recently reported by Yang et al. which achieves a stable operation potential of 4.2 V and energy density of 460 Wh kg −1 . [10] It is great progress but worthy noting that the energy density calculation is based on the mass of anode and cathode. When the mass of the electrolyte is included, the full-cell energy density is dropped to 304 Wh kg −1 , revealing the important role of battery configurational design.Structural engineering provides a feasible and universal way to further improve the energy density of LBs without changing the fundamental battery chemistries. Since the battery's energy only comes from the electrically active materials in the electrodes, the core principle for the novel structural design of batteries is to minimize the ratio of inactive components while maintaining or improving battery performance per mass or volume of active material. Common strategies include the optimization of battery packaging with thinner, more robust materials, the reduction of electrode porosity with a higher packing density and increased electrolyte uptake, and the utilization of thick electrodes. The first is relatively hard to improve in a short time and would require a breakthrough in battery packaging materials with carefully evaluated cost and safety parameters. As for the reduction of electrolyte, it is also difficult toThe ever-growing portable electronics and electric vehicle markets heavily influence the technological revolution of lithium batteries (LBs) toward higher energy densities for longer standby times or driving range. Thick electrode designs can substantially improve the electrode active material loading by minimizing the inactive component ratio at the device level, providing a great platform for enhancing the overall energy densi...

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.
