This study presents the fabrication and characterization of a phosphorene/MXene heterostructure-textured nanopiezocomposite as an asymmetric membrane electrode for lithium-ion batteries (LIBs). The phosphorene/MXene nanocomposite is prepared through a polar urea-assisted self-assembly strategy, which promotes uniform distribution of phosphorene and enhances piezoelectricity. The optimized phosphorene/MXene ratio is 1:3, providing a high reversible capacity of 1463 mAh g⁻¹ at 100 mA g⁻¹ and excellent cycling stability (420 mAh g⁻¹ for 1,000 cycles at 500 mA g⁻¹). The enhanced electrochemical properties are attributed to the increased active sites, improved conductivity, and the synergistic effect of phosphorene and MXene. The corrugated textured surface further facilitates lithium-ion transfer, contributing to the superior performance.This study presents the fabrication and characterization of a phosphorene/MXene heterostructure-textured nanopiezocomposite as an asymmetric membrane electrode for lithium-ion batteries (LIBs).
