Abstract: Electrolyte is very important in the study of rechargeable magnesium batteries. Electrode materials are limited by the electrolyte. In this paper，electrolyte materials are reviewed，including organic Grignard salt solution electrolyte and novel Mg ion conductive gel polymer electrolyte (GPE). The corresponding preparation technology and the main problems are also detailed. Finally，the development trend of the electrolyte of rechargeable magnesium batteries is discussed.
