Synthesis of MgMnSiO4 and Its Application as Cathode Material for Magnesium Battery

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.
