Nanostructured materials afford a promising potential for many energy storage applications because of their extraordinary electrochemical properties. However, the remarkable electrochemical energy storage performance could only be harvested at a relatively low mass-loading via the traditional electrode fabrication process, and the scale of these materials into commercial-level mass-loading remains a daunting challenge because the ion diffusion kinetics deteriorates rapidly along with the increased thickness of the electrodes. Very recently, three-dimensional (3D) printing, a promising additive manufacturing technology, has been considered as an emerging method to address the aforementioned issues where the 3D printed electrodes could possess elaborately regulated architectures and rationally organized porosity. As a result, the outstanding electrochemical performance has been widely observed in energy storage devices made of 3D printed electrodes of high-mass loading. In this review, we systemically introduce the basic working principles of various 3D printing technologies and their practical applications to manufacture highmass loading electrodes for energy storage devices. Challenges and perspectives in 3D printing technologies for the construction of electrodes at the current stage are also outlined, aiming to offer some useful opinions for further development for this prosperous field.

“…Thick electrode with a high active material mass loading is considered to be an effect strategy to improve the whole energy density of cells. [ 35 ] Hence, Li anode scaffold paired with thick LCO electrode with a high mass loading of ≈12.8 mg cm −2 was also conducted and the electrochemical performance was shown in Figure 5c. As shown, cells with the two kinds of Li electrodes delivered almost the same discharge capacity of ≈142.2 mAh g −1 at 0.2 C. However, at higher current densities, cells with Li anode scaffold demonstrated superior electrochemical performance with much higher discharge capacities of 136.6, 126.6, and 108.9 mAh g −1 at 0.5, 1, and 2 C, respectively, in sharp contrast to that of only 119.8, 105.1, and 86.5 mAh g −1 for cells with conventional Li foil (Figure 5c and Figure S8, Supporting Information).…”

The rapid development of modern society have stimulated intensive research on advanced energy storage systems with high energy density and high safety to meet the rising demand for large-scale energy storage systems, such as electric vehicles and smart grid. As one of the most promising anode candidates, Li metal has received much attention owing to its ultrahigh theoretical capacity (3860 mAh g −1 ), the lowest electrochemical potential (−3.040 V vs standard hydrogen electrode) and low density (0.534 g cm −3 ). [1,2] Nevertheless, the practical large-scale application of Li metal has long been fettered by serious safety challenges caused by the uncontrollable Li deposition during Li plating/stripping process, resulting in lithium dendrite growth which could penetrate the separator leading to battery failureThe large-scale implementation of lithium metal batteries (LMBs) has long been plagued by the uncontrollable Li deposition triggered safety issues. Herein, a lithiophilic three-dimensional Li anode scaffold, which is prepared by molten Li infusion aided by confined growth of low-cost Zn clusters, is rationally constructed for high-performance LMBs. Owing to the synergy of the carbon host and the effective regulation from the Zn nanoclusters, the large volumetric change of Li metal is well mitigated and shows a smooth and dendrite-free behavior. The Li anode scaffold can deliver much improved Coulombic efficiency, superior rate performance, and long cycle lifespan with much lower voltage polarization. Furthermore, the half cells of Li anode scaffold paired with LiFePO 4 /LiCoO 2 /sulfur can achieve a higher specific capacity and longer stable cycling life than those with conventional Li foil. The Li|LFP cells can achieve a stable cycling over 250 cycles at 1C with a higher capacity retention of ≈90.8%, and a higher initial discharge capacity of 924.6 mAh g −1 with a high capacity retention over 300 cycles can also be obtained in Li|S cells at 1C. This work demonstrates a cost-effective and scalable strategy for stable Li metal anode toward next-generation and high-performance LMBs. www.advancedsciencenews.com

“…Transition to the nanoscale is an effective way to improve the electrochemical performance of Li 4 Ti 5 O 12 . [5,6] The respective Li 4 Ti 5 O 12 nanoparticles with small size were prepared via various routes, including solid-state, hydrothermal, microwave, sol-gel, molten salt, combustion, and rheological phase methods [4,7,8]. Although Li 4 Ti 5 O 12 nanoparticles can deliver good electrochemical performance, complex synthesis processes limit its applications [9].…”

Li 4 Ti 5 O 12 /V 2 O 5 nanocomposites were synthesized by a one-pot co-precipitation method. The structure and morphology of the as-prepared materials were analyzed by X-ray diffraction and transmission electron microscopy. The results show that Li 4 Ti 5 O 12 /V 2 O 5 composites with different nano size were successfully synthesized. The Li 4 Ti 5 O 12 /V 2 O 5 sample (2 wt.% V 2 O 5 addition of Li 4 Ti 5 O 12 ) keep at a high discharge capacity of 169.9 mAh g − 1 after 150 cycles at 1 C. The existence of the V 2 O 5 reduces the size of Li 4 Ti 5 O 12 , which improve the electrochemical activity of the sample.
