A two-dimensional MXene/BN van der Waals heterostructure as an anode material for lithium-ion batteries

A q-Ti 3 C 2 T x /BNNS heterostructure was prepared by means of high energy ball-milling, and exhibited a long-term cycling stability with 84.4% capacity retention after 1400 cycles at 0.5 A g −1 .
