Abstract
- Repressing the hampers of poor electrical conductivity and pulverization is central for the applications of metal oxides anode materials, yet remains big challenge. To meet the target, pie-like graphene paper@Fe 3 O 4 nanorod arrays@carbon film is designed and fabricated as high-performance integrated electrode for lithium ion batteries. Graphene paper is selected as binder-free integrated substrate, which could accelerate electron transfer, buffer volume changes of Fe 3 O 4 , contribute to additional capacity, and endow the electrode with flexibility. The carbon film serves as the package to prevent the dissolution of Fe 3 O 4 into the electrolyte, extending the cyclic life of the integrated electrode. The architecture of Fe 3 O 4 nanorod array offers void space for volume buffer and fluid electrolyte infiltration. Based on the combined structural advantages, the present pie-like electrode with interior array architecture therefore exhibits excellent electrochemical lithium storage properties, especially large, stable, and durable cyclic performance at high current density (852 mA g −1 after 1000 cycles at 2 A g −1 ), making it a promising candidate as high-performance flexible electrode.
