摘要

Looking for low-cost materials for high energy storage has been a hot topic in recent years. Iron materials and biomass carbon, which both have the properties of good natural abundance and low cost, are very promising materials for large-scale use. Here, beta-FeOOH nanorods adhered to pine-biomass carbon (BC/FeOOH) were synthesized by a facile precipitation method. TEM and SEM results show that beta-FeOOH nanorods grow in the inner pores and are inserted into the surface pores. We analyzed the effects of the amount of BC in the composite on the electrode performance in Li-ion battery cells. The as-prepared composites showed excellent electrochemical performance as the anode electrode material in Li-ion batteries, which maintained a current density of 650 mAh g(-1) at 1 C (1 C = 1000 mAg(-1)) and above 660 mAh g(-1) at 0.2 C after 450 cycles.
