Currently, the potential of sodium-ion battery as an alternative to replace lithium-ion
battery have been widely studied, focusing on the exploration of anode and cathode
materials. Herein, the potential of Mn2O3 as anode materials is investigated since it
possesses high theoretical capacity (1018 mAhg -1 ). Mn2O3 were prepared by using
thermal decomposition of commercial MnCO3 and hydrothermally grown MnCO3 as the
metal precursor, respectively. The X-ray diffraction patterns for both Mn2O3 confirmed
that the samples do not have any impurities. From the scanning electron microscopy
images, Mn2O3 prepared from thermal decomposition of commercial MnCO3 were
having nanoparticles morphology, whereas it was polyhedral for hydrothermally grown
MnCO3. The polyhedral Mn2O3 exhibited the highest discharge capacity (85 mAhg -1 )
as compared to Mn2O3 nanoparticle (32 mAhg -1 ) when galvanostatically
charge/discharge at 0.1 C for 35 cycles. This result indicates that this material have a
potential to be explored as an anode materials for sodium-ion batteries.
