2D MXenes are highly attractive for achieving ultrafast and stable lithium/sodium storage due to their good electric conductivity and abundant redox active sites. While, effective strategies for scalable preparation of oligolayered MXenes are still under exploration. Herein, oligolayered Ti3C2Tx MXene is successfully obtained after conventional synthesis of multilayered Ti3C2 and subsequent delamination process via an organic solvent of tetramethyl-ammonium hydroxide (TMAOH). Comprehensive electrochemical study reveals that surface-controlled redox reaction dominated the charge storage behavior of oligolayered Ti3C2Tx with fast reaction kinetics. Impressively, the obtained oligolayered Ti3C2Tx exhibits excellent lithium/sodium storage performance, featured for a high specific capacity of 330 mAh·g-1 at 1.0 A·g-1 after 800 cycles for lithium storage and 280 mAh·g-1 at 0.5 A·g-1 after 500 cycles for sodium storage. Such impressive performance will advance the development of oligolayered Ti3C2Tx based materials for lithium/sodium storage and even broaden their application into energy storage.
