Abstract: Quantum dots (QDs) are emerging as a new class of zero-dimensional nanomaterials with semiconducting properties. Among many applications, QDs find useful employment in high-capacity electrodes in secondary batteries by virtue of their nanodimension. The recent advancements of QDs and their application as QD-based nanocomposites in electrodes are published in numerous accounts. Well-dispersed QDs in conductive carbonaceous materials can lead to the formation of nanocomposites with excellent cyclic stabilities and large reversible capacities, which are suitable for applications in many batteries. Inorganic QDs are also being investigated as potential candidates to fabricate nanocomposites in different secondary batteries. However, there are not many review articles available detailing the synthetic methodologies used to fabricate such QD-based nanocomposites along with their electrochemical properties. In this article, we are documenting a comprehensive review of a variety of QD nanocomposites with their manufacturing processes and successful utilization in battery applications. We will be highlighting the application of QD-based nanocomposites as anode and cathode materials for applications in different secondary batteries and discussing the enhancement of the electrochemical performances of such batteries in terms of energy density and cyclability.
