“…As we all know, doping N into carbon is beneficial for improving surface wettability, electronic conductivity, and energy storage performance. − For instance, Wang initially studied the effect of various nitrogen types on the performance of NVP by preparing a series of N-doped carbon-coated NVP composites with various molar ratios of N to C and found that all doped composites exhibited remarkably improved rate performance compared to the undoped one. Specially, Zhang and Kong et al − ,− confirmed the positive effect of N-doped carbon derived from the carbonization of PDPA on battery performance. However, so far, there is no report about PDPA-derived nitrogen-doped carbon coating for NVPF.…”

“…In an alkaline solution, DPA can easily self-polymerize by an oxidation cross-linking reaction and forms a complete and uniform polydopamine (PDPA) layer strongly attached to the surfaces of virtually all types of materials. − Also, the coating thickness of PDPA layers can be easily adjusted by polymerization time . Thus, polydopamine has become attractive in a new route of carbon coating for modifying electrode materials. − More importantly, the obtained continuous PDPA film can be further converted into a nitrogen-doped (N-doped) carbon layer after high-temperature sintering.

d Na 3 V 2 (PO 4 ) 2 F 3 (NVPF/C-PDPA) composites have been successfully prepared by self-polymerization of dopamine on the NVPF surface and subsequent sintering. The X-ray diffraction results show that the NVPF/C-PDPA has good crystallinity and introducing dopamine does not affect the lattice structure of NVPF. The high-resolution transmission electron microscopy, high-angle annular dark-field images, and energy dispersive X-ray spectroscopy analyses reveal that the NVPF/C-PDPA particles are covered by a complete and uniform covering layer, which is effective at preventing corrosion of NVPF in the electrolyte to greatly increase cycling stability. Furthermore, N-doping into the carbon layer can produce additional active sites to improve the capacity especially the rate capacity. Such a NVPF/C-PDPA electrode delivers a remarkable rate capacity (98.0 mA h g −1 at 10 C) and superior cycle performance (∼95.8% capacity retention at 10 C after 800 cycles). We believe that this work may be beneficial for accelerating the development of high-performance electrode materials and the commercialization of Na-ion batteries.

“…Moreover, the well resolved lattice fringes with an interplanar spacing of 0.72 nm, as exhibited in the inset, corresponding to the (001) crystal planes of δ-MnO 2 can be observed, which is also consistent to the XRD characterization. 35,36 Figure 4a exhibits the CV curves of the cathode of C-coated δ-MnO 2 nanoflakes on CC at the scan rate of 1 mV s −1 in the potential window of 1.0-2.0 V. Two separate reduction peaks were noticed around 1.17 and 1.36 V that can be attributed to the intercalation of H + and Zn 2+ into the δ-MnO 2 host structure, respectively, and the corresponding reduction of Mn 4+ to Mn 3+ . 37 In the meantime, there is a broad oxidation peak around 1.75 V that is attributed to the overlapped de-intercalation of Zn 2+ and H + from δ-MnO 2 accompanied by reinstatement of the Mn 4+ state.…”

Aqueous zinc (Zn)-ion batteries (AZIBs) are one of the most promising secondary battery technologies for electricity storage with high performance-to-cost ratios. Herein, a highly reversible AZIB using interconnected vertical δ-MnO2 nanoflakes coated by a dopamine-derived carbon thin shell of ∼2 nm in thickness on carbon cloth as a self-supporting cathode is reported. The vertical nanoflake structure ensures the effective contact with electrolyte, large specific surface area and efficient stress relief during charge and discharge processes, and the coated thin carbon shell increases the electrical conductivity of the cathode and meanwhile relieves the dissolution of the electrode material during cycle. Thanks to these advantages, a high capacity of ∼346.7 mA h g–1 at 0.5 A g–1 and good long-term cycling stability with 96.8% capacity retention after 2000 cycles at 6.0 A g–1 can be delivered. Furthermore, the electricity storage mechanism is investigated using various characterization tools. Benefiting from the facile preparation and high performance, this study is believed to provide a valuable exploration of high-performance self-supporting cathodes for aqueous Zn-ion batteries.

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.
