Description:
Aluminum has larger theoretical capacity of 2235 mAh/g than that of graphite (372 mAh/g), but it has big disadvantages including shorter cycle life and higher irreversible capacity loss. Improving cycle performance can be obtained via alloying of aluminum. In this paper, two ternary aluminum alloy, Al 7 Cu 2 Fe and Al 73 Cu 5 Fe 22 were prepared. The main phase of Al 7 Cu 2 Fe alloy was Al 7 Cu 2 Fe. The heat treatment increased the proportion of Al 7 Cu 2 Fe. The main phase of Al 73 Cu 5 Fe 22 alloy was Al 60 Cu 30 Fe 10 . The heat treatment reduced the proportion of Al 60 Cu 30 Fe 10 . For two alloys, the heat treatment could increase discharge capacity compared with cast alloy. The discharge capacity was improved by 50%. The content of aluminum in alloys has little effect on improving cycle perfor...
