Lithium-ion batteries have been the premier technology in modern portable devices and electric vehicles but they exhibit certain limitations such as mineral resources and cost. Recently, the search for alternative battery systems particularly based on earth-abundant elements has thus attracted remarkable attention. Of the possible substitute to lithium-ion, rechargeable magnesium (Mg) batteries are a potential candidate due to the abundance of Mg in the earth’s crust, as well as the high specific volumetric capacity (3833 mAh/cm-3), and good safety features of Mg metal.1 However, critical issues impeding commercialize Mg battery prototypes is the formation of surface blocking layer in conventional electrolytes which passivate and inactivate Mg metal anode, and limited selections of cathode material and electrolyte materials against Mg metal anode. To mitigate those issues, insertion-type anode materials have been developed as alternatives to Mg metal.2-4 Our recent works have shown that tin-based anode materials are capable of providing superior operating voltage and capacity for rechargeable Mg batteries.4 In this presentation, we report synthesis and characterization tin-based anode materials, and electrochemical studies with Mg-cells.
