The utility of carbon quantum dots (CQDs) based electrodes prepared from biomass has drawn the attention of the scientists and industrialists due to their structural diversities, tuneable physical or chemical properties, and economical, environmental, and social considerations. As the raw material for the production of CQDs is abundantly available in nature at low‐cost any technological know‐how is bound to be sustainable. These carbon quantum dots with porous structure have ideal architecture, physicochemical properties, amenability for doping with heteroatoms, good electrical conductivity thus making them very attractive for electrochemical energy storage. In this paper, application potentialities of various metal ion batteries (Li+, Na+, K+, Al2+, and Zn2+) using nanostructured carbon materials, Columbic efficiency, cyclic ability, reversible discharge capacity, current density, dimensional effects and cost considerations are brought into close focus.

“…pinecone have been pyrolyzed to achieve hard carbon resulting in different pore structures and/or doped elements. [57][58][59] The chemical nature of the precursors has indeed a complex effect on the microstructure, texture, and the content and type of heteroatoms of the as-generated hard carbon, leading to a difficult correlation to the structure and sodium storage behavior. Furthermore, the type of electrolyte also affects the electrochemical behavior, that is, certain carbons behave differently in different solvents.…”

Sodium ion batteries (SIBs) have been extensively investigated as a promising alternative for lithium ion batteries (LIBs) owing to the readily available character of sodium, lower costs of battery systems, as well as a similar working mechanism to LIBs. However, this view turns out to be oversimplified; countless reviews especially in the last years contradict each other, and it is still a challenging task to design highly performing electrode materials for SIBs. Due to the larger radius of Na+, its lower covalent character, and the resulting changes in intercalation chemistry, sodium is far from being only the bigger relative of lithium, and the difference leads to altered loading curves, and the occurrence of a multiplicity of binding sites. An in‐depth holistic understanding of the sodium storage mechanisms is needed to resolve the controversial discussions in the research community, ideally starting with unquestionable thermodynamic points. Here, taking a tutorial perspective, first the recent discussions on the storage mechanism of sodium in carbons are reviewed from an unorthodox viewpoint, namely addressing sodium uptake as a multifaceted adsorption process with an added electrochemical binding potential. This model is based on literature data. Afterward, challenges and perspectives revealed by such a model are discussed.

Given the merits of affordable cost, superior low‐temperature performance, and advanced safe properties, sodium‐ion batteries (SIBs) have exhibited great development potential in large scale energy storage applications. Among various emerging carbonaceous anode materials applied for SIBs, hard carbon (HC) has recently gained significant attention regarding their relatively low cost, wide availability, and optimal overall performance. However, the insufficient initial Coulombic efficiency (ICE) of HC is the main bottlenecks, which is inevitably hindering their further commercial applications. Herein, an in‐depth holistic exposition about the reasons causing the unsatisfied ICE and the recent advances on effective improvement strategies are comprehensively summarized in this review, which have been divided into two aspects including the intrinsic property (degree of graphitization, pore structure, defect, et al.) and the extrinsic factor (electrolyte, electrode materials, et al.). In addition, future prospects and perspectives on HC to enable practical application in SIBs are also briefly outlined.
