Abstract Scope |
The high-capacity/low-cost amorphous alloy anode materials was prepared by using mechanical alloying method. By manipulating the particle size of the nanophase and the amorphous phase and the ratio of the two phases, the performance of the amorphous alloy anode material was improved. And the nano metal and carbon form a conductive carbon network to improve the conductivity of the amorphous alloy anode material. The developed Sn-ZrFeNi-C amorphous alloy anode material has the characteristics of high reversible capacity. The Sn-ZrFeNi-C amorphous alloy material is used in the EC/EMC/DMC electrolyte. The initial reversible capacity of the material is 694 mAh/g and the irreversible capacity loss is 171 mAh/g, so it has a very high first-time efficiency up to 80%. Sn-ZrFeNi-C amorphous alloy material has twice the capacity of traditional graphite (330~350 mAh/g) anode material, but the cycle life of Sn-ZrFeNi-C amorphous alloy material needs to be improved. |
