Ti3C2/MoS2 composite as anode material for lithium-ion batteries — •Peng Guo^1,2, Yuquan Wu¹, Lennart Singer¹, Peter Comba², and Rüdiger Klingeler¹ — ¹Kirchhoff-Institut für Physik, Universität Heidelberg, Germany — ²Inorganisch-Chemisches Institut, Universität Heidelberg, Germany

MXene, represented by Ti3C2, has received increasing attention when applied as anode material for lithium-ion battery due to its superior conductivity and hydrophilicity. Since the application of MXene is limited by its low capacity, in this work, a PDDA-assisted electrostatic attraction method was used to assemble a Ti3C2/MoS2 composite. The microscopic morphology, crystalline features and microstructure of the Ti3C2/MoS2 composite materials studied by X-ray diffraction (XRD) and field emission scanning electron microscopy (FESEM) are reported. Electrochemical studies reveal a specific capacity of 747 mAhg-1, at 400 mAg-1, of the Ti3C2/MoS2 composite electrode which notably increases to 776 mAhg-1 after 30 cycles.
