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.

Carbon-coated lithium vanadium phosphate cathode materials were successfully prepared via an ultra-fast microwave irradiation route in 5 min with using activated carbon as the microwave adsorbent. We aimed to utilize this ultra-fast and facile route to shorten the synthesis procedure for obtaining Li3V2(PO4)3/C cathode material with superior rate capability. To characterize the intrinsic crystal structure and exterior architecture morphology of targeted material, X-ray diffraction pattern (XRD), scanning electron microscopy (SEM) in combined with transmission electron microscopy (TEM) were applied in experiment. The role of microwave irradiation treatment time in affecting the crystalline structure and related lithium-storage electrochemical performance is also investigated in detail. For the optimal Li3V2(PO4)3/C material, it delivered a specific discharge capacity of 110.1 mAh g−1 at a 0.2 C charging/discharging rate while hold a superior cycling stability over 50 cycles when tested at a 1 C rate. The ultra-fast synthesis route should pave a new way to save the energy in the preparation of phosphate-based electroactive cathode material.
