In this paper, MoO3 microrods was prepared using corn straw as biological template via roasting process．The components and crystal characterization of the material were investigated via X-ray diffraction(XRD), scanning electron microscopy(SEM), and the electrochemistry property and mechanism was studied．The results show that the MoO3 material synthesized by template method is Orthorhombic structures．And the MoO3 particles were submicron and micron rods with uniform distribution and a smooth surface. MoO3 microrods had an average diameter that ranged from 1 to 2 μm. The result indicated that the MoO3 as the new negative of aluminum battery delivers a higher discharge capacity of 190 mAh/g at a scanning rate of 1mv/s, which showing good capacity and cycling performance.

Prussian Blue type Na2MnFe(CN)6 was prepared by direct precipitation method and a subsequent drying procedure as a cathode material for aqueous rechargeable sodium-ion batteries. XRD patterns showed that Na2MnFe(CN)6 has a typical Prussian Blue structure with space group Fm3m. Na2MnFe(CN)6 presents good electrochemical behaviors at 10 mAg-1 discharge current density with specific capacity 73.1 mAhg-1 after 30 cycles. The results show that Na2MnFe(CN)6 could be a potential cathode material for aqueous Sodium-ion battery. [ABSTRACT FROM AUTHOR]

Orthosilicate MgMnSiO4 was prepared by sol-gel route and a subsequent heating procedure as a cathode material for rechargeable magnesium batteries. XRD patterns showed that MgMnSiO4 has a orthorhombic system with space group Pbnm(62). MgMnSiO4 presents good electrochemical behaviors at 10 mAg-1 discharge current density with specific capacity 130.1 mAhg-1 after 20 cycles. The results show that MgMnSiO4 could be a potential cathode material for high-energy magnesium secondary battery. [ABSTRACT FROM AUTHOR]
