Special Issue Information

Dear Colleagues,

The growing demands of energy and limited fossil fuel have accelerated the necessity to develop reliable energy storage technologies for the utilization of intermittent renewable energies, such as solar and wind energies. Batteries, especially lithium-ion batteries, have played an increasingly important role in our modern life since their successful launch in the market. However, the growing demand for electric vehicles and stationary energy storage systems requires batteries with a higher energy density, lower cost, longer cycle life and better safety than those that the current Li-ion batteries can offer. Thus, exhaustive efforts have been devoted to exploring new battery systems recently. On the path to developing advanced electrodes for new electrochemistry systems, nanocarbon and its derived materials have opened up frontiers in materials science and engineering issues. Carbon nanomaterials, mainly including carbon nanotubes/nanofibers, graphene, fullerenes and nanoparticles/quantum dots, have been intensively investigated for batteries over recent decades. The numerous varieties of nanocarbon make it capable of storing energy or serving as a host or conductive additive in battery electrodes.

The aim of this Special Issue is to tackle the following topics in nanocarbon-based energy storage systems: (i) sustainable and smart engineering of nanocarbon materials; (ii) the correlation among the nanostructure of carbon, charge storage mechanisms and the electrochemical performance; (iii) the working mechanisms of nanocarbon and its derived materials as anodes in emerging battery systems such as Na-ion batteries, K-ion batteries and multivalent-ion batteries; (iv) key parameters determining the properties of nanocarbon as a host or additive in new battery systems. To promote the comprehensive research progress on the application of nanocarbon to improve battery performance, we thereby invite authors to contribute original research and review papers covering the above topics and beyond.

Fast charging capability is highly desired for new generation lithium-ion batteries used in consumer-grade electronic devices and electric vehicles. However, currently used anodes suffer from sluggish ion kinetics due to limited interlayer distance. Herein, the coal-based semicoke was chosen as precursor to prepare cost-effective carbon anodes with high-rate performance through a facile pyrolytic strategy. The evolution of microstructure and its effect on electrochemical performance are entirely studied. The results show that large number of short-ordered defective structures are generated due to the occurrence of turbostatic-like structures when pyrolyzed at 900 °C, which are propitious to large interlayer distance and developed porous structure. High accessible surface area and large interlayer spacing with short-ordered defective domains endow the sample treated at 900 °C under argon (A900) with accelerated ion dynamics and enhanced ion adsorption dominated surface-induced capacitive processes. As a result, A900 delivers high capacity (331.1 mAh g−1 at 0.1 A g−1) and long life expectancy (94.8% after 1000 cycles at 1 A g−1) as well as good rate capability (153.2 mAh g−1 at 5 A g−1). This work opens a scalable avenue to fabricating cost-effective, high-rate, and long cycling life carbon anodes. Full article
