Facile fabrication and electrochemical performance of flower-like Fe3O4@C@layered double hydroxide (LDH) composite

Novel core–shell structured Fe₃O₄@C@Ni–Al LDH microspheres were prepared by a hydrothermal method following a facile in situ growth process. The as-prepared product exhibits high pseudocapacity (767.6 F g⁻¹), good rate capability, and remarkable cycling stability (92% after 1000 cycles).
