MoS2 has attracted tremendous attention as a promising electrode material for rechargeable alkali metal ion (Li+ , Na+ , K+ ) batteries due to its high capacity and low cost. However, the practical application of MoS2 for energy storage has not been achieved yet, which is restricted by its intrinsic charge-storage behavior. Debates still exist in this field although great efforts have been made to reveal alkali metal ion (Li+ , Na+ , K+ ) storage mechanism of MoS2 . This Minireview aims to provide an analysis and summary of the related phase conversion, structure collapse, and loss of active material in a MoS2 electrode during the intercalation/extraction process of alkali metal ions. Hence, the fundamental understanding about the charge storage in MoS2 is of importance for the rational design of MoS2 electrodes with excellent electrochemical performance.
