dc.description.abstract | The three-dimensional (3D) graphene aerogel (GA)-wrapped LiFePO4 submicron-rod composite (LFP@GA) has been prepared successfully through a solvothermal method followed with rapid freezedrying. Monodispersed LiFePO4 submicron-rods are well-enwrapped with the graphene sheets and which further form a highly porous and conductive 3D structure, leading to the overall rapid electron transport of the composite electrode and affording many interwoven pores for fast supply of Liþ and storage of electrolyte. Moreover, the combination of the rod-shaped LFP and porous 3D structure can effectively relieve the stress resulted from the structural change during the insertion/deinsertion of Liþ. Owing to these particular structure and characteristics, the LFP@GA composite presents a high discharge capacity (162.7 mAh g_1 at 0.1 C), a remarkable rate capacity (119.9 mAh g_1 at 5 C) and an excellent long-term cycle stability after 1000 cycles at 1 C (86.5% capacity retention), which is potential for use in Li-ion batteries. | nb_NO |
