In this era of exponential growth in energy demand and its adverse effect on global warming, electrochemical energy storage systems have been a hot pursuit in both the scientific and industrial communities. In this regard, supercapacitors, Li-ion batteries, and Li–S batteries have evolved as the most plausible storage systems with excellent commercial adaptations. Intending to get the best performance from these systems, researchers all over the world have been engaging to develop various new methods for the synthesis of advanced carbon materials with a target of economical viability, abundance, low cost, and ease of preparation. Among them, activated carbon has proven to be an attractive electrode material due to its many advantageous properties such as a large surface area, high pore density, good conductivity, low cost, and good mechanical and chemical stability compared to other alternatives, such as high-cost graphene, carbon nanotubes, Mxenes, transition metal complexes, and conducting polymers. Among the numerous synthetic and biological resources that are used for the synthesis of activated carbon, coal/coal-like materials have found tremendous importance in recent times due to their relative abundance, extremely low cost, and excellent large-scale production possibilities. The present review attempts to collect all the significant innovations carried out for the use of cheap and economically viable coal-derived/-based activated carbon and its composites in supercapacitors, Li-ion batteries, and Li–S batteries and to critically evaluate their comparative performances. The progress in advanced three-dimensional printing technology for these energy storage applications is also discussed. The highlight of this review is also to assess the challenges that remain for the synthesis of high-performance electroactive-activated carbon materials from coal-based resources as alternative electrode materials, which would become promising candidates in the foreseeable future.

“…Moreover, two strong bands are observed for the FRC at 1340 and 1585 cm –1 , assigning to the disordered (D) band and the graphite (G) band. The I D / I G ratio of FRC is 0.81, which is higher than that of common carbon, indicating that FRC contains more defects and vacancies because of its puffed and loose structure, which will promote Li + and electron transport. , The increasing I D / I G ratios of the FRC/NP-Si@C composites (Figure d) with increasing Si loading verify that the introduction of Si can add the disorder degree of the compounds. The robust microsphere structure with 3D conducting nanosized porous channels can both enhance the conductivity and relieve the volume expansion of Si during an electrochemical reaction.…”

To relieve the volume expansion of silicon during the lithium insertion/desertion process, we designed fluffy rice carbon/nano-Si@C (FRC/NP-Si@C) composites with a stable structure via spray drying, a large-scale produced low-cost approach. Nanosilicon particles are fixed in robust microspheres assembled from FRC and pitch carbon while forming three-dimensional (3D) conducting nanosized porous channels. FRC/NP-Si@C composites, as anodes for lithium-ion batteries, display outstanding cycling and rate performances at room temperature owing to their special structure. They exhibit a reversible capacity of 600 mAh g −1 at 0.1 A g −1 after 200 cycles as well as stable capacities of 1688.2 and 579.8 mAh g −1 at current densities of 0.1 and 1.6 A g −1 , respectively, indicating their use as alternative anode materials for lithium-ion batteries (LIBs).

Carbon based nanomaterials are acknowledged for their admirable optical, electrical, mechanical characteristics and broad class of applications. Choice of precursor and simple synthesis techniques have decisive roles in viable production and commercialization of carbon produce. The intense demand to develop high purity carbon nanomaterials through inexpensive techniques has promoted usage of fossil derivatives as feasible source of carbon. Coal serves as a naturally available, abundant and cheap feedstock for carbon materials. From the crystalline clusters of aromatic hydrocarbons in a cross-linked network, carbon nanostructures can easily be extracted through green synthesis routes. It promotes a potent alternative for the cost effective and scaled up production of nanocarbon. The well-developed pores distribution, presence of numerous active sites and appropriate migration channels for ions enhance the electrochemical parameters necessary for the fabrication of supercapacitors, batteries and electrochemical sensors. The metallic impurities contained in coal contribute towards faradic redox reactions required for an efficient electrode modification. In this review, the potential uses of coal based carbon nanomaterials in energy storage and environmental sectors are discussed in detail.
