As one kind of carbon nanomaterials, since their discovery at the beginning of the century, carbon dots (CDs) have been attracting extensive attention in sensing, bioimaging, catalysis, organic light-emitting diodes, etc. due to their rich and diverse physical and chemical properties. Although the precise structures of CDs need to be further analyzed and elaborated, it is confirmed that there are many functional groups on the surfaces including amino, hydroxyl, carboxyl and thiol, depending on the precursors and preparation processes used. The crystalline/amorphous conjugated graphite-like sp2 domains and segments inside the CDs provide good electrical conductivity and photoelectric conversion capability. The applications of CDs in electrochemical energy storage have been carried out extensively and become a hot topic in recent years. In this review, the recent progress about the applications of CDs in typical electrochemical energy storage devices including supercapacitors, lithium-ion batteries, sodium-ion batteries and potassium-ion batteries is outlined and summarized. The relationships between material structures and device performances are mainly analyzed. Finally, it is anticipated that the development of CDs can continuously boost the study of high-efficiency energy storage devices profoundly.

“…Carbon nanomaterials are considered as ideal lithium deposition carriers because of their lightweight, robust electrical conductivity, high mechanical flexibility, good electrochemical stability, and low cost. − The theoretical specific capacity of graphite anode is much lower than that of LMAs, so much attention is focused on the development of lithium/carbon-based composite electrodes. In this regard, lithiophilic materials such as porous carbon nanofibers, graphene, and graphene oxide are acknowledged to be the main materials of composite lithium anodes. − Typically, the carbon nanotube (CNT) has good thermal and mechanical properties, as well as good electrical conductivity, and Li-CNT composites have good dendrite inhibition property and high specific capacity. , However, because of its small size, the composites have high activity, leading to severe spontaneous combustion even in dry air. , To address this issue, the lithium/carbon composite anode containing fluorocarbon nanotubes (Li/FCNT, only 1.6 wt %) was prepared by the melting-impregnation method and had significantly enhanced chemical and electrochemical stability compared to lithium metal.…”

If meeting the industrial demand for energy storage technology to power the next-generation smart systems is the problem, then lithium metal as an anode for lithium metal batteries (LMBs) could be our best solution. It has the lowest negative electrochemical potential, ultrahigh theoretical specific capacity, and ultralow mass density. However, the high reactivity of lithium metal under environmental conditions triggers serious corrosion or safety problems. Therefore, air stability and water resistance are important factors in the design of practical LMBs. Herein, we review the research status and the latest progress of interface engineering and architecture design for protection of the lithium metal anode (LMA) in air and water. First, a brief introduction is given to highlight the importance of developing air-stable and waterproof LMAs for high-energy batteries. Then, the key strategies including the use of protective layers, modified electrolytes, and composite lithium anodes proposed in recent years are comprehensively classified for suppressing the oxidation or corrosion of LMAs in air and water. Finally, this review puts forth the current challenges and scrutinizes various strategies for LMA protection and proposes possible future perspectives for continuous development of air-stable and water-resistant LMAs. This review will be a helpful guideline for constructing high-energy-density LMBs in practical applications.

Lithium metal, as the “Holy Grail” of lithium battery anodes, is promising to be used in the next‐generation of high‐energy‐density storage devices. However, serious safety risk and poor cycle performance are inevitable when bare lithium foil is used as the anode material, due to the uncontrolled growth of lithium dendrites, unstable solid electrolyte interface, and infinite volume expansion of lithium during cycling, which largely hinder the further commercial application of lithium metal batteries (LMBs). The utilization of up‐to‐date current collectors with specific composition and structure is believed to be effective to overcome these shortcomings. However, a systematic evaluation of the merit of different current collector materials for realizing high‐performance lithium metal anodes is still lacking. This review summarizes the fashionable advanced current collector materials for long‐life LMBs in recent years. The superiorities and related electrochemical performances by using these current collector materials are discussed in detail. It is expected that this review may promote the rational choice of appreciatory current collector materials with unique structure designs to extend the cycle life of lithium metal anodes for achieving the next‐generation of high‐energy‐density LMBs.
