Zinc–air batteries (ZABs) are promising as energy storage devices owing to their high energy density and the safety of electrolytes. Construction of abundant triple‐phase boundary (TPB) effectively facilitates cathode reactions occurring at TPB. Herein, a wood‐derived integral air electrode containing Co/CoO nanoparticles and nitrogen‐doped carbonized wood (Co/CoO@NWC) is constructed with a dual catalytic function. The potential gap between oxygen reduction and evolution is shortened to 0.77 V. Liquid ZABs using Co/CoO@NWC as cathode exhibit high discharge specific capacity (800 mAh gZn−1), low charge–discharge gap (0.84 V), and long‐term cycling stability (270 h). Co/CoO@NWC also shows distinguished catalytic activity and stability in all‐solid‐state ZABs. The inherent layered porous and pipe structures of wood are well maintained in catalytically active carbon. The different hydrophilicity of carbonized wood and Co/CoO endow abundant TPBs for battery reaction. The Co/CoO located on TPB provides main active sites for oxygen reactions. The inherent pipe structures of wood carbon and the interaction between Co/CoO and NWC effectively prevent nanoparticles from aggregation. The design and preparation of this monolithic electrocatalyst contribute to the broad‐scale application of ZABs and promote the development of next‐generation biomass‐based storage devices.

“…Besides, compared to current industrial electrode preparation, 3D printing technique is immature and limited to lab-scale research. [321,322] It is still a long way for large-scale fabrication of high mass loading electrode by 3D printing technique in practical applications within a short time and at a low cost. iv) The high mass loading electrode exhibits poor rate/cycling performance and face serious self-discharging issue than thin electrodes.…”

vehicles (HEVs), because of their high energy density and long lifetime. [1][2][3] In recent years, the ever-growing demand on electric vehicles contributes to the continuous growth of the battery market, and the energy storage devices of EVs/HEVs raise stern demands on higher energy density (>300 Wh kg −1 ) and lower cost (500 Wh kg −1 ), and the standard parameters for different electrode systems toward this high energy density goal are well summarized in the previous works. [7][8][9] In particular, the innovative battery chemistries (i.e., Li-metal battery and all-solid-state lithium battery) using Li metal as anode, exhibit much higher energy density than current lithium-ion batteries, whereas some technological issues are needed to be addressed first, such as dendrite formation suppression, industrial battery Current lithium-ion battery technology is approaching the theoretical energy density limitation, which is challenged by the increasing requirements of ever-growing energy storage market of electric vehicles, hybrid electric vehicles, and portable electronic devices. Although great progresses are made on tailoring the electrode materials from methodology to mechanism to meet the practical demands, sluggish mass transport, and charge transfer dynamics are the main bottlenecks when increasing the areal/volumetric loading multiple times to commercial level. Thus, this review presents the state-of-the-art developments on rational design of the commercialization-driven electrodes for lithium batteries. First, the basic guidance and challenges (such as electrode mechanical instability, sluggish charge diffusion, deteriorated performance, and safety concerns) on constructing the industry-required high mass loading electrodes toward commercialization are discussed. Second, the corresponding design strategies on cathode/anode electrode materials with high mass loading are proposed to overcome these challenges without compromising energy density and cycling durability, including electrode architecture, integrated configuration, interface engineering, mechanical compression, and Li metal protection. Finally, the future trends and perspectives on commercializationdriven electrodes are offered. These design principles and potential strategies are also promising to be applied in other...

“…In view of a mature integrated circuit, electric-driven 3D microactuators may be employed more widely due to their advantages [52,175]. For example, the sensor signal needs to be changed into an electrical signal to facilitate processing, while electrically driven microactuators enable the actuator and sensor components to be integrated [52,176]. The two large gaps that need to be bridged for practical electrical-driven 3D microactuators are materials and manufacturing strategies [177][178][179].…”

Microactuators, which can transform external stimuli into mechanical motion at microscale, have attracted extensive attention because they can be used to construct microelectromechanical systems (MEMS) and/or microrobots, resulting in extensive applications in a large number of fields such as noninvasive surgery, targeted delivery, and biomedical machines. In contrast to classical 2D MEMS devices, 3D microactuators provide a new platform for the research of stimuli-responsive functional devices. However, traditional planar processing techniques based on photolithography are inadequate in the construction of 3D microstructures. To solve this issue, researchers have proposed many strategies, among which 3D laser printing is becoming a prospective technique to create smart devices at the microscale because of its versatility, adjustability, and flexibility. Here, we review the recent progress in stimulus-responsive 3D microactuators fabricated with 3D laser printing depending on different stimuli. Then, an outlook of the design, fabrication, control, and applications of 3D laser-printed microactuators is propounded with the goal of providing a reference for related research.
