Rechargeable Zn‐based batteries provide a compelling supplement to subsistent energy storage devices owing to their high energy density, good safety, and low cost. Nevertheless, inherent imperfections such as dendrite growth, side reactions, and andante reaction kinetics, severely impede their commercialization. As new 0D nanomaterials, carbon dots (CDs) with unique characteristics and excellent electrochemical activity, exhibit promising potential exploitation in electrochemistry and electrocatalysis areas. Herein, the adhibition of CDs in resolving the aforementioned drawbacks of Zn‐based batteries is introduced. To begin with, concepts, physicochemical properties, and synthetic methods of CDs are discussed. Next, recent developments and advances exploiting CDs in respectively ameliorating the performance of the Zn anode, the cathode, and electrolytes of Zn ion batteries and bifunctional electrocatalytic activities including oxygen reduction reaction and oxygen evolution reaction for Zn‐air batteries, are roundly reviewed and minutely generalized. Finally, current challenges and prospects are surveyed as well, aiming to offer a reference for the blossom of advanced Zn‐based batteries.

Aqueous zinc‐ion batteries (AZIBs) possess high theoretical capacity and good safety, making them highly hopeful for large‐scale energy storage applications. Nevertheless, the uncontrolled growth of Zn dendrites on anode significantly reduces the cycle life of AZIBs. In this study, a series of porphyrin‐based porous organic polymers (CuTAPP‐NTCDA‐POP and ZnTAPP‐NTCDA‐POP) are synthesized using aminophenylporphyrin (TAPP) and aromatic dianhydride, which are served as porous protective coating layers for Zn anode. The coating effectively prevents the formation of Zn dendrites and guides the deposition of Zn2+ because of the abundance of zincophilic sites. As expected, the symmetric cells equipped with the optimum ZnTAPP‐NTCDA‐POP@Zn anode demonstrate a longer cycle life of over 1200 h at 0.5 mA cm−2 compared to bare Zn (64 h). Moreover, when the ammonium vanadate (NHVO) cathode is coupled with ZnTAPP‐NTCDA‐POP@Zn anode, the resulting full cell displays superior cycle stability that sustains over 350 cycles with a higher invertible capacity (225 mAh g−1 at 1 A g−1). This performance surpasses that of a full cell equipped with just a bare Zn anode. This work proposes a viable strategy to address Zn dendrites, presenting a promising horizon for the widespread application of AZIBs.
