“…All in all, using 3D hosts has been shown to successfully stop metal dendrite formation. As demonstrated in [83,145], zinc [157,158], sodium batteries [150,159], the higher specific surface areas of 3D hosts can lower local current densities and homogenize interface charge distributions, enabling uniform plating of metal ions. The technology and material choices for 3D hosts are relatively diverse.…”

Three-dimensional (3D) printing, one of the additive manufacturing techniques, is being broadly utilized to develop a variety of electrochemical energy storage devices (EESDs) (for instance, batteries, super-capacitors) from the nanoscale to the macroscale due to its excellent manufacturing flexibility, geometric designability, low cost, and eco-friendliness. Recent studies have reported the usage of 3D-printed critical materials for EESDs, which have demonstrated excellent electrochemical performances, including high energy densities and rate capabilities, due to the improved ion/electron transport abilities, and fast kinetics. However, the recent structural design and application of 3D printed critical materials for EESDs, especially rechargeable batteries, have been rarely summarized and discussed in the latest reported reviews. In this review, we concentrate on current progresses in 3D printing critical materials of emerging batteries. We begin by outlining the typical features of major 3D-printing methods used for fabricating EESDs, including design principles, materials selectivity, and optimization strategies. We then summarize recent progress in 3D-printed critical materials (anode, cathode, electrolyte, separator, and current collector) for secondary batteries, including conventional Li-ion (Na-ion (SIBs), K-ion (KIBs)) batteries, Li/Na/K/Zn metal batteries, Zn-air, and Ni-Fe batteries, in which the section of 3D printing precursor, the design principle of 3D structures, and the working mechanism of electrodes are discussed. In the end, we discuss the major challenges and potential applications in developing 3D-printed critical materials for rechargeable batteries. Keywords: additive manufacturing; 3D printing; rechargeable batteries; electrochemical energy storage devices; lithium-ion battery.

“…Hence, Li@CNT/MXene/SnO 2 anode provides excellent rate performance and long-term cycling stability. Wang et al 135 applied 3D printing to generate lithiophilic gradient 3D hosts with electronic conductivity by manipulating the γ-Al 2 O 3 concentrations in each layer of materials (Figure 7e). Combined with the fast Li + conductivity and high lithiophilicity at the Li− Al−O interface, the prepared lithiophilic gradient hosts can achieve a long-term cycling life of more than 1500 h at 1 mA cm −2 and 1 mAh cm −2 .…”

Lithium metal batteries have been attracting an abundance of attention recently as a powerful competitor of the next-generation advanced energy storage technologies. However, lithium dendrite formation can result in decreased battery lifespan and even safety issues, inhibiting the widespread application of lithium metal batteries. The conductive hosts of lithium metal anode are proven to be an effective method to prevent lithium dendrite formation and achieve outstanding electrochemical performance of lithium metal batteries. However, the surface deposition of Li ions decreases the utilization of the conductive host. Therefore, this Review introduces the design principle and recent advances to render the bottom-up deposition of a lithium metal anode. On one hand, conductivity and lithiophilicity gradient hosts are summarized to realize the “bottom-up” lithium deposition and efficiently limit the growth of lithium dendrites. On the other hand, the future prospects and challenges of host design associated with the “bottom-up” lithium deposition technique are discussed. This Review intends to provide novel insights for the development of gradient materials design and lithium metal batteries with long lifespan and high safety.

“…In recent years, lithium-ion batteries, by virtue of their high specific energy, long life, and excellent ability to operate over a wide temperature range, have been gradually applied to various types of space equipment such as spaceships, space stations, and communication and navigation satellites and have become the third-generation power source in the field of space exploration. − However, these lithium-ion batteries used in space equipment are mainly based on organic liquid electrolytes, , which are flammable, explosive, and prone to degradation, presenting a safety hazard. The adoption of all-solid-state lithium batteries with a high safety factor will promote the miniaturization, , lightweight, and low power consumption of the equipment, which is expected to be applied in space missions such as exploring Mars, Jupiter, and the Moon in the future .…”

Garnet-type lithium−lanthanum−zirconium−oxygen (LLZO) oxide solid-state electrolytes (SSEs) have become one of the most promising SSEs for future deep space exploration because of their excellent energy density and mechanical strength. However, the effects of high-energy irradiation on LLZO-type oxide SSEs in the space domain are still unknown. To this end, the Ta-doped lithium−lanthanum−zirconium−tantalum−oxygen (LLZTO) SSE with high ionic conductivity at room temperature was prepared by a solid-phase reaction method, and the γirradiation effects on the cell structure and performance (ionic conductivity, hardness, and elastic modulus) of the LLZTO SSE were investigated in detail. The results show that the γ-irradiated electrolyte did not produce other heterogeneous phases, but the lattice spacing was subsequently reduced, which would be detrimental to the ionic transport in the lattice. In addition, the neutron diffraction data also illustrate that irradiation does not change the cell structure of the LLZTO SSE, but the decrease in Li1 occupancy at the tetrahedral-24d site will have a detrimental causal effect on ion transport. The impedance test at room temperature further demonstrated that after γ-irradiation, the total resistance of LLZTO becomes larger and the ionic conductivity of the corresponding irradiated samples tends to decrease. Fortunately, the ionic conductivity retention of irradiated samples at low temperatures was higher than that of unirradiated samples (48.45 > 29.9%). The test results of nanoindentation indicate that the irradiated samples have high mechanical properties at a low load (2 mN), which can effectively prevent lithium dendrite penetration, and this is supported by the low electronic conductivity of the irradiated samples at room temperature. The first use of γ-irradiation to probe its effect on the cell structure and properties (electrochemical and mechanical) of the LLZTO oxide SSE has important research implications for the development of oxide SSEs for aerospace applications.
