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...

“…This hierarchical porous structure notably reduced the resistance of the cell (see Figure d), indicating a faster ion transport in the ITN defined by the 3D printed architecture. Another example is a 3D‐printed cathode based on LiMn 1− x Fe x PO 4 (LMFP) nanocrystals reported by Pan and co‐workers . As shown in Figure e–g, in this study, the authors employed carbon‐coated LMFP nanoparticles as the AM and printed the electrode with width around 450 µm and height of 18 µm.…”

portable electronics, cell phones, electrical vehicles (EVs), aerospace, etc. For advanced batteries, higher and higher energy density and/or power density, long cycling stability, good device safety, and low-cost are the primary goals. Since the energy density is mainly dependent on the specific capacity and loading level of active materials (AMs), AMs usually dominate the volume and weight inside the batteries. Because of this, tremendous efforts have been focused on high-performance AMs. However, the electrochemical performance of energy storage devices (ESDs) is fundamentally determined by a collective contribution or teamwork of all the components: AMs, electrolyte, separator, conductive agent, binders, etc. More importantly, with the increasing interests on high-capacity AMs (e.g., silicon, sulfur, Li-rich cathode, etc.), it becomes very clear that the "traffic system" (i.e., the charge transport system) plays very critical roles in the performance of the high-capacity AMs. Take silicon anode for example, a durable and flexible conductive network inside the electrode composite has been vital for addressing the big volume change issue. In this case, high-performance binders and conductive agent that can generate advanced conductive network are the keys. [2] In addition, with the increasing interests on EVs and flexible electronics, building a powerful and robust charge transport system inside ESDs is an urgent and critical task to support fast charging/ discharging capability and even flexibility of ESDs. In short, with the fast development of energy storage technologies, EVs, cell phones, etc., there is a critical, urgent, and challenging task on building powerful and durable charge transport system in next-generation advanced ESDs. Charge Transport Inside ESDsThe thriving of big cities highly relies on a powerful traffic system that transports the people, foods, products, etc. Similar to this picture, ESDs are powered by the transportation of charges, including both ions and electrons. As illustrated in Figure 1a, one can analogize the charge transport system and AMs in the electrodes of ESDs to the traffic system and buildings (i.e., host system of people), respectively. This analogy example not only help to explain the relationship between The charge transport system in an energy storage device (ESD) fundamentally controls the electrochemical performance and device safety. As the skeleton of the charge transport system, the "traffic" networks connecting the active materials are primary structural factors controlling the transport of ions/electrons. However, with the development of ESDs, it becomes very critical but challenging to build traffic networks with rational structures and mechanical robustness, which can support high energy density, fast charging and discharging capability, cycle stability, safety, and even device flexibility. This is especially true for ESDs with high-capacity active materials (e.g., sulfur and silicon), which show notable volume change during cycling. Therefore, there is an ur...

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.
