MXenes have great application prospect in energy storage fields due to a series of special physicochemical properties. However, the is greatly limited low intrinsic capacity. Here, through spray drying and vapor deposition methods, N-doped Ti3C2Tx phosphorus composites (N-Ti3C2Tx/P) were prepared for first time. The red particles absorbed walnut-like N-Ti3C2Tx matrix, facilitating transport Li+ electrons. When used as anodes lithium-ion batteries, battery can cycle up 1040 cycles with high stable capacity 801 mAh/g at 500 mA/g. Impressively, there an obvious increase subsequent higher current density increment interlayer spacing nanosheets. XPS measurements confirm that Ti-O-P bond was formed composites, granting robust structure leading superior performances during cycling. facile synthesis method by will facilitate development other 2D materials combined high-capacity storage.
