Lithium Storage

As anode material for lithium-ion batteries, graphite has the disadvantage of relatively low specific capacity. In this work, a simple yet effective strategy to overcome the disadvantages by using a composite of flake graphite (FG) and small-sized graphene (SG) has been developed. The FG/SG composite prepared by dispersing FG and SG (90:10 w/w) in ethanol and drying delivers much higher specific capacity than that of individual component except for improved rate capability. More surprisingly, FG/SG composite delivers higher reversible capacity than its theoretical value calculated according to the theoretical capacities of graphite and graphene. Therefore, a synergistic effect between FG and SG in lithium storage is clearly discovered. To explain it, we propose a model that abundant nanoscopic cavities were formed due to physical adhesion between FG and SG and could accommodate extra lithium.

Fe3O4@C spheres were synthesized by hydrothermal reaction at 190°C followed by a low temperature heat annealing at 600 °C and applied as an anode material for lithium-ion batteries. The samples were characterized by XRD and SEM. The electrochemical performances of as-synthesized Fe3O4@C were systemically investigated. A reversible capacity of 873 mAh g-1 is obtained in the second cycle at 400 mA g-1. More importantly, the discharge specific capacity can still maintain at about 767 mAh g-1 after 80 cycles. Moreover, Fe3O4@C spheres electrode shows satisfactory rate capability even at a rate up to 2000 mA g-1. Thus, the results demonstrate that Fe3O4@C spheres show encouraging application potential to be an advanced anode material for lithium storage
