“…Wang and co‐workers presented a highly branched N‐doped graphitic as anode for Li‐ion batteries. Compared with the flat tube domains, there are many structural defects and edge defective sites in the branched portions, which provide abundant storage sites for lithium ions, thus achieving high storage capacity and fast storage of lithium ions (Figure b) …”

The reasonable design of electrode materials for rechargeable batteries plays an important role in promoting the development of renewable energy technology. With the in‐depth understanding of the mechanisms underlying electrode reactions and the rapid development of advanced technology, the performance of batteries has significantly been optimized through the introduction of defect engineering on electrode materials. A large number of coordination unsaturated sites can be exposed by defect construction in electrode materials, which play a crucial role in electrochemical reactions. Herein, recent advances regarding defect engineering in electrode materials for rechargeable batteries are systematically summarized, with a special focus on the application of metal‐ion batteries, lithium–sulfur batteries, and metal–air batteries. The defects can not only effectively promote ion diffusion and charge transfer but also provide more storage/adsorption/active sites for guest ions and intermediate species, thus improving the performance of batteries. Moreover, the existing challenges and future development prospects are forecast, and the electrode materials are further optimized through defect engineering to promote the development of the battery industry.

“…), [38,39] especially graphene-like 2D ultrathin nanomaterials which result in a wealth of unprecedented functionalities, [40,41] have exhibited a large superiority for LIBs. [18,46,[56][57][58][59][60][61][62] These fascinating features can effectively avoid the self-aggregation of active nanomaterials, and benefit the insertion/extraction of Li + , so that excellent cycling and rate performances can be obtained. [42][43][44] One main problem is that although exhibiting higher capacity, these simplex lowdimensional nanomaterials still suffer from the serious selfaggregation and pulverization during cycling caused by their quite large surface area and energy, which makes nanomaterials lose their advantages, and consequently leads to poor cycling and rate performance.…”

IntroductionWith the economic, science and technology increasing at an amazing speed, energy has become one of the most important issues in the 21 st century. In addition, the supply of fossil With revolutionary electric vehicles and the smart grid fast developing, more advanced energy storage technologies become quite crucial issues. Li-ion batteries (LIBs) and Na-ion batteries (NIBs) are considered as the most promising electrochemical energy storage technologies. Low-dimensional nano-structural electrode materials can greatly increase the specific capacity, but they still suffer from poor cycling and rate performances due to their serious self-aggregations. Constructing 3D structures, such as micro/ nano-structures and free-standing electrodes, is a quite promising method to address the above issues. Such 3D structures can simultaneously avoid the disadvantages of low-dimensional nanomaterials, and preserve their advantages. As one group of promising high-capacity and low-cost electrode materials, vanadium-based oxides have exhibited an quite attractive electrochemical performance for energy storage applications in many novel works. However, their systematic reviews are quite limited, which is disadvantageous to their further development. Herein, this article provides an overview of vanadium-based oxides in the applications of LIBs and NIBs by focusing mainly on the aspect from low-dimensional nanomaterials synthesis to 3D micro/nano-structures and free-standing electrodes fabrication. Moreover, a feasible strategy to controllably fabricate the 3D micro/nano-structure for the whole vanadium-based oxides family is presented. Furthermore, and importantly, a quite promising solution method for the practical commercialized applications of vanadium oxides cathode materials in the future is proposed, i.e., fabricating the "vanadium oxides-based cathode/solid electrolyte/Li metal anode-type" all solid-state secondary-ion batteries.

“…As an example, graphene, a single layer of carbon atoms arranged in a hexagonal lattice, is an appealing material for photonics and electronics [23][24][25]. Conventional graphene materials can absorb photons from visible to infrared range [26,27] and exhibit a huge electrical mobility up to 200,000 cm 2 V −1 s −1 for a free sheet for both electrons and holes [28], which promote ultrafast conversion of photons or plasmons [29] to electrical currents or voltages for photo response.…”

Photodetectors based on two-dimensional (2D) nanostructures have led to a high optical response, and a long photocarrier lifetime because of spatial confinement effects. Since the discovery of graphene, many different 2D semiconductors have been developed and utilized in the ultrafast and ultrasensitive detection of light in the ultraviolet, visible, infrared and terahertz frequency ranges. This review presents a comprehensive summary of recent breakthroughs in constructing high-performance photodetectors based on 2D materials. First, we give a general overview of 2D photodetectors based on various single-component materials and their operating wavelength (ultraviolet to terahertz regime). Then, we summarize the design and controllable synthesis of heterostructure material systems to promote device photoresponse. Subsequently, special emphasis is put on the accepted methods in rational engineering of device architectures toward the photoresponse improvements. Finally, we conclude with our personal viewpoints on the challenges and promising future directions in this research field.
