Herein we report that novel two-dimensional (2D) Ti3Si0.75Al0.25C2 (TSAC) nanosheets, obtained by sonically exfoliating their bulk counterpart in alcohol, performs promising electrochemical activities in a reversible lithiation and delithiation procedure. The as-exfoliated 2D TSAC nanosheets show significantly enhanced lithium-ion uptake capability in comparison with their bulk counterpart, with a high capacity of ≈350 mAh g−1 at 200 mA g−1, high cycling stability and excellent rate performance (150 mAh g−1 after 200 cycles at 8000 mA g−1). The enhanced electrochemical performance of TSAC nanosheets is mainly a result of their fast Li-ion transport, large surface area and small charge transfer resistance. The discovery in this work highlights the uniqueness of a family of 2D layered MAX materials, such as Ti3GeC2, Ti3SnC2 and Ti2SC, which will likely be the promising choices as anode materials for lithium-ion batteries (LIBs).

Abstract It is urgent to explore high-capacity and efficient anode materials for rechargeable lithium-ion batteries (LIB). For borophene and phosphorene, two configurations are considered to form a heterojunction: twist angles of 0º (I) and 90º (II). There is a less degree of mismatch and larger formation energy in the formation of a B/P heterojunction, implying that borophene and phosphorene form the stable heterojunction. The heterojunctions of these two configurations demonstrate good conductivity, and the electrons near the Fermi level are mainly provided by borophene. Very importantly, the low energy barrier for interlayer migration of Li is observed in configuration I (0.14eV) and II (0.06 eV), and the migration of Li on the borophene and phosphorene side of the heterojunction still maintains its original energy barrier in bare monolayer. Moreover, the two configurations show the theoretical capacity as high as 738.69 and 721.86 mA h g-1, respectively, which is comparable to bare phosphorene. Furthermore, compared with bare phosphorene, the average voltage is greatly reduced after the formation of heterojunction. Hence, the overall electrochemical properties of the B/P heterojunction have been enhanced by combining the advantages of the individual phosphorene and borophene monolayers, which guarantees the B/P heterojunction as a good candidate for the anode material used in Li-ion batteries.
