Climate change and the energy crisis have promoted the rapid development of electrochemical energy-storage devices. Owing to many intriguing physicochemical properties, such as excellent chemical stability, high electronic conductivity, and a large specific surface area, porous carbon materials have always been considering as a promising candidate for electrochemical energy storage. To date, a wide variety of porous carbon materials based upon molecular design, pore control, and compositional tailoring have been proposed for energy-storage applications. This focus review summarizes recent advances in the synthesis of various porous carbon materials from the view of energy storage, particularly in the past three years. Their applications in representative electrochemical energy-storage devices, such as lithium-ion batteries, supercapacitors, and lithium-ion hybrid capacitors, are discussed in this review, with a look forward to offer some inspiration and guidelines for the exploitation of advanced carbon-based energy-storage materials.

“…However, mass production of high-quality carbon nanomaterials through environmentally-friendly and inexpensive strategies remains a signicant challenge. Considering the above factors and the factors affecting the performance of supercapacitors, [3][4][5][6] the key to electrochemical performance of supercapacitors is to design a green, simple and efficient method to obtain hierarchical porous carbon materials with both high specic surface area and reasonable pore structure, such as carbide-derived carbon, 7 carbon onions, 8 carbon nanotubes (CNTs), 9 carbon aerogels, 10 template porous carbon 11 and carbon nanobers (CNFs). [12][13][14] It is common knowledge that CNFs as one of the typical onedimensional nanomaterials not only provide pathways shortened for the rapid transportation of electrons, but also facilitate the penetration of electrolyte along the direction of the ber diameter, as well as supplying a high active area to electrochemical reactions.…”

The development of new materials to improve interfacial charge transfer characteristics will drastically improve energy storage, heterogeneous catalysis, and many other electrochemical applications. Here, we report a simple procedure that can harness the Faradaic nature of residual iron nanoparticle catalysts that endure within multi-walled carbon nanotubes (MWNT) post-synthesis, thereby alleviating the challenges associated with forging hybrid nanocomposite electrodes. Nonpurified MWNTs, undergo a chemical oxidation process in acidic conditions with KMnO 4 to partially "unzip" the MWNTs and expose the redox-active iron nanoparticles to the electrolyte. A stable redox peak associated with the Fe 2 + /3 + transition is achieved during the MWNT oxidation process yielding a~350 % increase in capacitance (> 300 F g À 1 ) relative to purified MWNT electrodes (70 F g À 1 ). While these materials solely may be pragmatic as energy storage electrodes, the integration of redox species within an inert carbon electrode will also provide new opportunities to accelerate heterogeneous charge transfer reactions.
