Özet
MnCr₂O₄ (M) and carbon-coated MnCr₂O₄ composites were synthesized via the glycine–nitrate combustion method and evaluated as potential anode materials for lithium-ion batteries (LIBs). Sucrose (S), polyethylene glycol (P), and multi-walled carbon nanotubes (MWCNT’S) were employed as carbon sources to enhance the electrochemical performance of MnCr₂O₄. Among these composites, the M-S-P-C electrode exhibited the highest discharge capacity and improved cycling stability, delivering 310 mAh/g under 50 mA/g current density after 50 cycles. This excellent electrochemical behaviour is attributed to its interconnected nanosheet morphology and porous architecture, which facilitate efficient ion transport and enlarge the electroactive surface area. Detailed analyses of the pristine and carbon-composited MnCr2O₄ samples were conducted using X-ray powder diffraction (XRD), Brunauer emmett eller (BET) surface area measurements, energy-dispersive X-ray spectroscopy (EDX), and field emission scanning electron microscopy (FESEM).
