ABSTRACT
The rapid development of electrochemical energy storage (EES) systems is inseparable from the continuous exploration of high-performance electrode materials. Two-dimensional (2D) transition metal dichalcogenides (TMDs) have attracted considerable attention as promising materials for EES applications owing to their large specific surface area and high theoretical capacity. Meanwhile, 2D TMDs provide short paths for ion transportation as well as high surface area for ion adsorption, which play key roles in improving many aspects of EES devices. However, the practical applications of 2D TMDs are still hindered by their poor rate performance and large volume change during charge/discharge cycling. In this chapter, the synthetic strategy and the electrochemical reaction mechanisms of 2D TMDs-based nanomaterials have been briefly summarized. Furthermore, we have reviewed recent advances of 2D TMDs-based nanomaterials and their applications were also summarized for stable lithium/sodium-ion (Li/Na-ion) batteries. This work aims to provide an effective reference for the development of 2D TMD nanomaterials as high-performance electrode materials for Li/Na-ion batteries.
