Special Issue Information

Dear Colleagues,

Due to the rapid depletion of fossil fuels and increasingly serious environmental issues facing the world, sustainable renewable energy conversion devices are now receiving great attention, as are sustainable energy storage devices. Recently, carbon-based nanomaterials have been extensively studied as excellent candidates for electrochemical energy storage applications due to their high conductivity, chemical stability, enhanced surface area, and excellent electrical properties. As a result, they are attracting increasing amounts of attention among the scientific community. Generally, the electrochemical storage properties of carbon-based nanomaterials are highly dependent on the design of their nanoarchitectures. Thus, efforts have been made to develop novel and improved methods of carbon nanomaterial synthesis, which would allow us to obtain the desired parameters (morphology, nanotexture, surface composition, etc.), resulting in differences in their chemical and physical properties and, thus, their electrochemical performance. This scientific field is blooming, with many new ideas and discoveries being made, while, at the same time, challenges that need to be thoroughly studied and overcome in the future are being identified.

This Special Issue will focus on discussing the synthesis, design, development, and fundamental advances made in various carbon-based nanoarchitectures (graphene, carbon nanotubes, carbon nanofibers, carbon quantum dots, etc.) for applications in electrochemical energy storage. We invite researchers to submit their original results on relevant topics. All types of contributions, including full-length research articles, review articles, and short communications, are welcome.

Silicon could revolutionize the performance of lithium-ion batteries (LIBs) due to its formidable theoretical gravimetric capacity, approximately ten times that of graphite. However, huge volume expansion during charge/discharge processes and poor electronic conductivity inhibited its commercialization. To address the problems, new carbon-silicon core-shell microparticles have emerged for prospective anodes in LIBs. In this study, we develop a core-shell structure by using hard carbon derived from phenolic resin as the core and nano silicon/pitch coating as the shell to the resulting HC@Si-P composite anode. A composition-optimized 20 wt.% pitch coated-Si/HC composite anode delivers superior cycling stability over 200 cycles under 1 A/g current density, showing a 398 mAh/g capacity. At 5.0 A/g current density during charge and discharge processes, the reversible capacity reaches 215 mAh/g. Upon reducing the current density to 0.1 A/g, the capacity remains high at 537 mAh/g. Impedance testing shows that after pitch coating, the RSEI impedance decreases and the diffusion coefficient of HC@Si-P increases. Moreover, the facile and scalable preparation technique is encouraging for the potential practical application of silicon-based anode materials of this type in the upcoming generation of LIBs.

Carbon is predominantly used in zinc-ion hybrid capacitors (ZIHCs) as an electrode material. Nitrogen doping and strategic design can enhance its electrochemical properties. Melamine formaldehyde resin, serving as a hard carbon precursor, synthesizes nitrogen-doped porous carbon after annealing. Incorporating transition metal catalysts like Ni, Co, and Fe alters the morphology, pore structure, graphitization degree, and nitrogen doping types/proportions. Electrochemical tests reveal a superior capacitance of 159.5 F g−1 at a scan rate of 1 mV s−1 and rate performance in Fe-catalyzed N-doped porous carbon (Fe-NDPC). Advanced analysis shows Fe-NDPC’s high graphitic nitrogen content and graphitization degree, boosting its electric double-layer capacitance (EDLC) and pseudocapacitance. Its abundant micro- and mesopores increase the surface area fourfold compared to non-catalyzed samples, favoring EDLC and fast electrolyte transport. This study guides catalyst application in carbon materials for supercapacitors, illuminating how catalysts influence nitrogen-doped porous carbon structure and performance. Full article
