Abstract Recent studies dedicated to layered van der Waals crystals have attracted significant attention magnetic atomically thin offering unprecedented opportunities for applications in innovative magnetoelectric, magneto‐optic, and spintronic devices. The active search original platforms the low‐dimensional magnetism study has emphasized entirely new properties of two dimensional (2D) semiconductor CrSBr. Herein, first time, electrochemical exfoliation bulk CrSBr a non‐aqueous environment is demonstrated. Notably, crystal cleavage governed by structural anisotropy occurred along directions forming few‐layered nanoribbons. exfoliated material possesses an orthorhombic crystalline structure strong optical anisotropy, showing polarization dependencies Raman signals. antiferromagnetism exhibited multilayered gives precedence ferromagnetic ordering revealed nanostructures. Furthermore, potential application nanoribbons pioneered photodetector fabrication demonstrates its responsivity up 30 µA cm −2 visible spectrum. Moreover, CrSBr‐based anode lithium‐ion batteries high performance self‐improving abilities. This anticipates that results will pave way toward future practical magneto‐ optoelectronics.
