Description
Summary:An attempt has been made to synthesize chloride free Magnesium salt. Magnesium Diethylphosphate (Mg(DEP)) by adopting a novel and economically viable chemical route. The salt is dissolved in N,N‐Dimethylformamide (DMF) and used as electrolyte for rechargeable magnesium battery (RMB). Reversible magnesium dissolution and deposition was examined in Mg‐half cell and full cell at varying potential windows. The reversible Mg intercalation and de‐intercalation at graphite cathode was analyzed by cyclic voltammetry, galvanostatic charge‐discharge and impedance analysis. Mg‐Graphite full cell has shown a discharge capacity of 70 mAh/g for 180 cycles. The cycled electrode's SEM, XRD, XPS analysis conclude the plausible Mg‐ions intercalation into the graphite. The studies could help in the development of chloride free Mg salts with potential application to serve as electrolyte for RMBs. Synthesis of Magnesium Diethylphosphate (Mg(DEP)) by adopting a novel and economically viable chemical route. Mg(DEP) is helping for the chloride free Mg salts with potential application to serve as electrolyte for Rechargeable Magnesium Batteries (RMBs). The salt is dissolved in N,N‐Dimethylformamide (DMF) and used as electrolyte for (RMBs). The reversible Mg intercalation and de‐intercalation at graphite cathode is examined. Mg‐Graphite full cell has shown a discharge capacity of up to 70 mAh/g for 180 cycles.
