Abstract Bi 2 MoO 6 is a potentially promising anode material for lithium-ion batteries (LIBs) on account of its high theoretical capacity coupled with low desertion potential. Due to conductivity and large volume expansion/contraction during charge/discharge cycling , effective modification indispensable address these issues. In this study, plate-to-layer /Ti 3 C T x (MXene) heterostructure proposed by electrostatic assembling positive-charged nanoplates negative-charged MXene nanosheets. nanosheets in the act as highly conductive substrate load anchor nanoplates, so improve electronic structural stability. When mass ratio optimized 30%, /MXene exhibits specific capacities 692 mAh g −1 at 100 mA after 200 cycles 545.1 99.6% coulombic efficiency 1 A 1000 cycles. The results provide not only high-performance lithium storage material, but also an strategy that could intrinsic issues various transition metal oxides anchoring them form heterostructures use materials LIBs.
