Lithium-ion batteries (LIBs) have played a significant role in various applications, such as powering electronics and electric vehicles. However, due to the rising cost of lithium and its limited availability in the earths crust arises, doubts whether the LIBs only have the capability to meet the increasing energy demand in the transportation sector in the future. Hence, researchers viewed sodium-ion batteries (SIBs) as a viable alternative to lithium-ion batteries (LIBs) for future energy storage applications due to the abundant availability of sodium resources, and their excellent electrochemical performance as comparable to that of LIBs. But, the commercialization of Na-ion batteries has been hindered by the degradation of conventional anode material performance and their unstable performance. To address these issues, Carbon Nanotubes (CNTs) based metal sulfide (MS) composites were recently employed as anode materials due to their low cost and higher gravimetric capacities. This review discusses the recent advancements in carbon nanotube-based metal sulfide anode materials, their various synthesis methods, morphological characteristics, and electrochemical properties. Finally, we also present strategies for increasing the electrochemical performance of future-generation SIBs. Graphical abstract: Carbon nanotube-based anodes make sodium-ion batteries stronger.
