LiFePO4 nanoparticle and graphene loaded carbon nanofibers for use of lithium-ion battery cathodes. |
초록 |
LiFePO4/Graphene/C nanofibers, in which LiFePO4 nanoparticles were encapsulated in graphene-containing carbon nanofiber matrix, were synthesized by electrospinning. Graphene was used in order to increase the conductivity of the composite. Polyimide (PI) fabricated by first electrospinning of the pre-polymer, poly(amid acid) ammonium salt (PAAS) then imidizing the electrospun nanofiber was used as the electrospinning media and the carbon source. The morphology and microstructure of LiFePO4/Graphene/C nanofiber were characterized using scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Electrochemical performance of LiFePO4/Graphene/C nanofibers was evaluated in coin-type cells. Both graphene and PI contribute to improve electrochemical performance of lithium batteries cathode sesulting in the enhancement of capacity and cycling ability. |
