Mesoporous magnesium manganese silicate as cathode materials for rechargeable magnesium batteries

摘要

Mesoporous magnesium manganese silicate materials were prepared using mesoporous silica SBA-15 or KIT-6 as both template and silicon source. The materials exhibited improved electrochemical intercalation and deintercalation toward Mg~(2+), compared with the corresponding bulk material.rnIt is well known that the morphology and surface area of materials have a profound effect on the electrochemical properties of electrodes for energy conversion and storage. With the rapid development of mesoporous nanostructures, recent strategies have focused upon the synthesis of electrode materials with mesoporous structure.
