摘要：

Orthorhombic magnesium manganese silicate (Mg1.03Mn0.97SiO4) was prepared and evaluated as a new cathode material for rechargeable magnesium batteries. Although the electrochemical activity of the Mg1.03Mn0.97SiO4 synthesized by high-temperature solid-state reaction is low, the magnesium storage capacity of nanosized Mg1.03Mn0.97SiO4 prepared by modified sol-gel route and in situ carbon coating reaches 244 mAh g(-1). The capacity increase mechanism during charge/discharge cycling was also preliminary studied. (C) 2008 Elsevier B.V. All rights reserved.
