Quantum dot-carbonaceous nanohybrid composites: preparation and application in electrochemical energy storage

Abstract

Quantum dot (QD)-based materials have been employed to enhance thermodynamic and kinetic properties of electrochemical reactions for energy storage and engineering. Nonetheless, the high reactivity, chemical instability, material agglomeration and low electrical conductivity of QDs are still the main challenges in their large-scale application. In this review, we compiled the state-of-the-art research activities on QD-carbonaceous-based nanohybrids in rechargeable energy storage applications, including lithium-ion batteries (LIBs), sodium-ion batteries (SIBs), potassium-ion batteries (PIBs), lithium–sulfur batteries (LSBs) and supercapacitors. In addition, the corresponding storage mechanisms of representative examples are discussed, and perspectives on future research directions are provided to facilitate further innovation and research in this field.
