tunable porous structures, various morphologies, and high electron conductivity, which makes them very attractive in many different fields of applications, such as energy storage, absorption, water filtration, drug delivery, catalysis, and sensing. [3] Their unique properties can be utilized in various kinds of templates, substrates, capsules, and decorations, especially in energy storage research fields. [4] Due to global concerns about greenhouse gas emissions from the fossil fuels and climate change, many renewable energy technologies have been extensively developed and investigated to alleviate the reliance on the traditional fossil energy sources. [5] In order to store the intermittent forms of energy such as wind energy and solar energy, rechargeable batteries are widely considered as one of the best types of power storage for large-scale electrical energy storage systems (EESs). [6][7][8] In the past few decades, lithium-ion batteries (LIBs) have dominated the power source markets for advanced electric vehicles and portable electronics, since they possess the obvious advantages of high energy density and long cycle life. [9] Nevertheless, the low abundance, uneven distribution, and high price of lithium are increasingly hindering its application in the energy storage area. [10] Sodium-ion batteries (SIBs), which share a similar electrochemical nature, have been considered as the most promising low-cost alternative candidates to the commercial LIBs, especially for the EESs and smart grid applications, owing to the high abundance of sodium sources worldwide. [11,12] Considerable efforts and progress have been made toward transferring the successful experience on the LIB system to SIBs, especially in terms of electrode materials. Both the anode and cathode materials suffer, however, from sluggish reaction kinetics, lower specific capacity, and less electrochemical activity because of the large ionic radius of Na + (1.02 Å for Na + vs 0.76 Å for Li + ). [13,14] Furthermore, graphitic carbon is almost electrochemically inactive in SIBs. Therefore, developing desirable electrode materials for high performance SIBs, especially desirable anode materials, is still an urgent task that is necessary for the real application of SIBs. [15][16][17][18] Unlike the intercalation-type materials, most of the anode materials for SIBs store Na + ions through alloying reactions Over the past decades, porous carbonaceous and carbon-incorporated composites have aroused tremendous attention owing to their unique properties such as high surface area, excellent accessibility to active sites, tunable morphologies and structures, and superior mass transport and diffusion. They have been widely investigated and applied in various fields, such as energy storage, absorption, water filtration, drug delivery, catalysis, and sensing. In the energy storage area, rechargeable sodium-ion batteries (SIBs) have attracted tremendous attention as the next-generation power plants for large-scale energy storage systems (EESs). However, their low ene...

The Construction of advanced electrode materials can push the boundaries of electrochemical performance of energy storage devices and accordingly open up a booming energy storage market. Typically, porous carbon is one of the most widely used materials in the field of batteries due to its attractive properties including large porosity, high electronic mobility, good mechanical strength and chemical stability, and ultrahigh specific surface area. This review focuses on diverse synthetic methods of multiscale porous carbon nanomaterials including direct carbonization, electrospinning, puffing, hydrothermal methods, and chemical vapor deposition, with and without templates, as well as their applications in different rechargeable secondary batteries. We summarize different dimensional porous carbon (1D, 2D and 3D) with controlled pore sizes and analyze their formation mechanisms. Additionally, the structure-activity relationship of multiscale porous carbon nanomaterials is reviewed in detail. Meanwhile, we propose general guidelines to fabricate multiscale porous carbon nanomaterials with large surface area and high conductivity. Finally, future prospects and development trends on the advanced multiscale porous carbon nanomaterials toward construction of next-generation batteries are presented.
