Synthesis and characterization of cathode material for rechargeable magnesium battery technology

Synthesis and characterization of magnesium manganese spinel (MgMn2O4) as cathode material for magnesium (Mg) secondary battery were reported in this paper. Wet chemical (coprecipitation) method was employed where graphite was used with precipitate for one sample. X-ray diffraction (XRD) analysis revealed formation of crystalline MgMn2O4 for both samples. Scanning electron microscopy (SEM) micrographs demonstrated that flake shape MgMn2O4 was formed by simple coprecipitation method, while nano spheroids of spinel were formed from precipitate having graphite. Carbon powder (μm) and carbon nano tube (CNT) were added to the cathode material as conductive additive separately. Electrochemical characterization exhibited promising results as cathode material for nano structured spinel for Mg secondary battery where carbon nanotube was added as conductive additive. © 2015, National Institute of Optoelectronics.
