Abstract Scope |
The effects of the chlorine content used as electrolyte should be controlled in the recycle process of Mg-air battery. The influence of MgCl2 and NaCl in Si-thermic reduction of MgO has been studied in this study. The mixture of MgO with MgCl2 or NaCl was reduced by metallic Si at 1150C° for 3h, and the reduction rate was estimated. The reduction rate without MgCl2 or NaCl addition was about 55% under our reduction condition, and 1mol% addition of MgCl2 rarely affected the reduction rate. However, the reduction rate decreased with added amount of MgCl2. and became about 15% in 10mol% addition. Even 1mol% addition of NaCl worsened the reduction rate, and the reduction rate decreased with the addition amount. It is confirmed that the chlorine content should be removed before Si-thermic reduction in the recycle of Mg-air battery. |
