説明
<p>The effect of electrolyte additive 1,2-dichloroethane (DCE) on the electrochemical stability of aluminum-graphite battery using acetamide-AlCl3 electrolyte is investigated comparatively. Original dendritic and dead aluminum are observed in Al-Al cells at a high operation rate. Original dendritic and dead aluminum are observed in the anode and separator of Al-Al cells at a high operation rate. DCE is a preferred electrolyte additive to reduce the polarization of the acetamide-AlCl3 electrolyte. Furthermore, DCE can effectively suppress the dendrites on the Al anode in Al|acetamide-AlCl3|Al cells. Besides, it has a positive effect on improving the discharge specific capacity and cycle stability of aluminum-graphite batteries with a high coulombic efficiency over 300 cycles. This result indicates that organic additive is suitable to improve the electrochemical performance of aluminum-graphite batteries.</p>
