- Summary:
- Recently, high energy density battery attracts public attentionwith the application to power source of electric vehicle andelectric energy storage system in solar and wind generation.Magnesium electrode has large theoretical capacity as much as 3839mAh cm-1. Besides, magnesium compounds are abundant in theearth's crust and most of them are nontoxic. Therefore,rechargeable magnesium battery, whose negative electrode reactionis magnesium deposition / dissolution, is one of the most expectedcandidates.However, rechargeable magnesium deposition and dissolution isnot achieved in most electrolytes. Magnesium has extensively highreactivity, leading the formation of surface films in theelectrolytes. These films cannot conduct magnesium ion and inhibitmagnesium deposition and dissolution reactions. So far, reversiblemagnesium deposition and dissolution can be achieved only in RMgX(R = alkyl or aryl, X = halogen), Mg(BR4)2 or Mg(AlCl2RR')2 /ether solutions [1,2,3]. In these solutions, magnesium is thought not to becovered with surface films. However, since these solutions havelimitation for the battery electrolyte, due to their thermal andchemical instability, studies for more proper electrolytes areneeded.In this work, we focused on the electrolyte consisting ofmagnesium bromide and 2-methyltetrahydrofuran (2-MeTHF), which werecomposed of Grignard reagents. The electrochemical behavior ofplatinum electrode in the solution and the analysis of depositswere studied in detail
