| Abstract: | The metal iron ions in the leaching solution of copper clad by microbiological method were recovered and the added value of
the leaching solution of copper clad was improved. The octahedral and spherical Fe2O3/graphene composites were prepared by using
the iron ions obtained by hydrothermal method and assembled as a negative electrode for lithium ion battery. The results show that
the specific volumes of Fe2O3/graphene composites with octahedral morphology are higher than that of spherical, and the octahedral
Fe2O3/graphene composites are circulated at 100 mA/g, and the first discharge and charge specific volumes are as high as 1 343 and
970 mAh/g, after 47 cycles, the discharge and charge specific volumes are 769 and 740 mAh/g, respectively. |
