In response to the current policy of high storage capacity, two-dimensional (2D) materials have revealed promising prospects as high-performance electrode materials. MoB, a type such material, is widely regarded an anode candidate for Li-ion batteries due its large specific surface area and abundant ion diffusion channels; long-term cycling stability, however, poor owing material pulverization during cycle. Therefore, MoB/Si3N4 heterojunction in this work proposed with Si3N4 acting skeleton, maintaining stability structure, while retaining energy properties MoB well. addition, certain built-in electric field formed between them, which can play role regulating charge transfer, improving transport channel, accelerating migration rate. Herein, structural, electronic, electrochemical are systematically investigated by first-principles calculations; final results indicate that does indeed fields, promote possess excellent electrical conductivity outstanding property. Meanwhile, introduction vacancy defects bolster kinetic performance greatly reduce barrier Li ions, conducive realization rapid discharge battery. Based on synergistic effect two single-component materials, synthesized displays theoretical capacity 461 mAh/g, calculated open-circuit voltage 0.66 V, within range negative criterion 0–1 effectively preventing formation dendrites; these comparable other 2D Given intriguing properties, exceptional advanced LIB
