“…With the ongoing research of global scientists, it is expected that coal-based activated carbon composite anode materials for Li-ion batteries are being used in a variety of fields, including individual movable tools or hybrid vehicles. A huge number of excellent studies focusing on the benefits of porous coal-based porous graphitic carbon materials/composite materials in Li-ion batteries for energy storage devices have nicely documented the implementation progress in research and development. − However, there is limited research in coal-based carbon materials for such technologies despite having a good supply chain of coal materials. Table summarizes the Li-ion batteries’ performances of different coal-derived anode materials, and it was observed that there is a serious need to explore abundant coal resources for producing good quality carbon materials to use in Li-ion batteries.…”

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.

All‐solid‐state Li batteries (ASSBs) promise better performance and higher safety than the current liquid‐based Li‐ion batteries (LIBs). Sulfide ASSBs have been extensively studied and considerably advanced in recent decades. Research on identifying suitable cathode materials for sulfide ASSBs is currently well established, with great progress being made in the commercialization of layered cathodes in the liquid‐based LIBs. Research on anode materials for sulfide ASSBs is of great importance for enhancing the battery energy density. However, it seems that little has been published that summarizes studies of anode materials for sulfide ASSBs and suggests future research directions. Thus, within this Minireview, we aim to provide an overview of previous and current research focused on anode materials for sulfide ASSBs and to suggest a future research direction for developing suitable anode systems for sulfide ASSBs.

“…Not only the thin film, but Si powder has also been started to be used in the all-solid-state LIBs (Arthur et al, 2018;Kato et al, 2018;Okuno et al, 2019). A slurry mixture consisting of Si, solid electrolytes, and acetylene black was shaken in a centrifuge tube with ZrO 2 balls and coated onto a carbon-coated copper foil electrode (Yamamoto et al, 2018).…”

This mini review article summarizes the recent progress of the all-solid-state lithium ion batteries (LIBs) with high-capacity anodes. Although the theoretical capacity of silicon (Si) is exceptionally high, the large volume change during cycling is a severe drawback for practical applications. The volume change of the active materials leads to mechanical degradation and electrical contact loss, resulting in a poor cycling performance. Recently, the number of reports about Si anodes in liquid electrolytes has significantly increased, leading to the better understanding of the electrochemical performances of Si. For the realization of the LIBs with a high capacity and safety, highcapacity alloy anodes are highly required to be used in all-solid-state batteries. However, at the present stage, research studies of high-capacity anodes with solid electrolytes are scarce compared to the vast amount of reports using liquid electrolyte. The selection of solid electrolytes is also a key factor for the stable performance of high-capacity anodes in the all-solid-state batteries, while previous studies on Si anodes have mainly focused on the fabrication of the hollow structured anodes for reducing their volume expansion. This review will provide some reports about the cycling properties of highcapacity anodes in the all-solid-state batteries and the solid electrolyte interface (SEI) formation at the anode interface of solid electrolytes. The potential of the high-capacity anodes for practical applications in all-solid-state batteries will be discussed.
