Rechargeable magnesium battery is a potential candidate as an alternative to lithium-ion battery for use in energy storage systems due to low cost, high specific volumetric capacity (3833 mAh/cm3) and reasonable gravimetric capacity (2205 mAh/g). However, the development of Mg cells still faces many challenges. The formation of electrochemically inactive surface blocking layer on Mg metal anode prohibits its reversible reaction in electrolyte containing commercially available magnesium salts such as Mg(TFSI)2 or Mg(ClO4)2 in room temperature polar aprotic solvents. To mitigate those issues, insertion-type anode materials have been introduced as alternatives to Mg metal. Our recent works have demonstrated that tin-based materials have a high potential for use as anode active materials in Mg-ion batteries at room temperature. In this presentation, we will report the synthesis and characterization tin-alloy materials, and their electrochemical behavior in room temperature Mg-ion cells. |
