摘要: In this work, mixed (electron and ion) conducting LiFePO4/graphene composites have been prepared through a facile hydrothermal route followed by heat treatment. It was found that the LiFePO4 particles adhered to surface of graphene and/or embedded in nanosheets. As result, an effective three-dimensional network formed bridging nanosheets, which can facilitate electron transport effectively thus improve kinetics rate performance LiFePO4. The (92:8 wt.) exhibited discharge capacity 160.3 mAh g(-1) at 0.1 C 81.5 10 C, respectively. comparative investigation on proved establishing with has potential enhance specific capability (C) 2010 Elsevier B.V.
