“…Batteries and electrochemical capacitors (ECs), which are also called super capacitors, are the two most important applications for CQDs. Javed et al 20 prepared CQDs from the chemical oxidation of D-(+)-glucose. The CQDs possess a quasi-spherical structure with facile storage and transport channels for lithium and sodium-ions.…”

“…Nevertheless, Abbas et al. prepared uniformly sized and evenly distributed CQDs as anode materials, which exhibited a long cycle life and a fast rate capability (Figure A) . Such CQDs‐anode materials retain Li storage capacity of 864.9 mAh g −1 after 500 cycles at a current rate of 0.5 C, while the capacity is 415.8 mAh g −1 at 10 C, which is ascribed to their high conductivity, rapid ion transport, and a stable electrical layer, and a steady performance with a minimal efficiency loss.…”

Lithium-ion battery (LIB) is a dominating power source in the market owing to its high energy density, good cycling stability and environmental benignity. However, technical challenges remain after years' optimization and commercialization, which are detrimental to the expected performance and lifespan of LIBs. For instance, many cathode materials of LIBs suffer from rapid capacity fading and poor high-rate performance, which are ascribed to self-aggregation, dissolution and fast increased charge transfer resistances during cycles. In terms of the anode materials, low coulombic efficiency, electrolyte depletion and safety issues are common. In addition, the liquid electrolyte systems trigger safety concerns because flammable and volatile organic solvents are necessary. Recently, carbon dots (CDs) emerge as a sound material to address those challenges of LIBs, and also present promising applications in bioimaging, fluorescence sensing, photo/electro-catalysis, and electroluminescence. This review will overlook the state-of-the-art advances in the employment of CDs based composites to build cathode/anode materials and electrolytes in LIBs, through tailoring the internal structures and the surface states of electrode materials, and being additives in electrolyte, to improve the performances of the next-generation LIBs. The major challenges and opportunities in front of CDs in LIBs will be outlined and discussed in detail.

“…Besides, they are known to cause rapid ion transport, change in buffer volume and also to provide continuous conduction pathways. They have stable electrical double layer leading to a constant performance with a minimum loss of efficiency 28, 29. In addition, the abundant functional groups present on the surface of CQDs act as coordination sites with transition metal ions.…”

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.
