摘　　要：采用金属铝片和金属锂片组装纽扣电池。通过电化学性能测试和充放电前后Al片的X射线衍射分析及SEM显微观察,表明在合适充放电条件下,Al与Li形成金属间化合物,具有较高的电化学容量和一定的循环性能。Aluminum plate and lithium plate were combined to make button cells. The results of electrochemical test, XRD analysis and SEM observation indicated that aluminum formed intermetallic compound with lithium under appropriate chargedischarge conditions. The compound has a large electrochemical capacity and certain circulating capacity.
