Novel Biomass-derived Hollow Carbons as Anode Materials for Lithium-ion Batteries
A novel hollow carbon derived from biomass lotus-root has been prepared by a one-step carbonization method. The carbon anode obtained at 900 °C showed the best electrochemical performance, corresponding to a high specific capacity of 445 mA·h/g at 0.1 C, as well as excellent cycling stability after 500 cycles. Further investigation exhibits that the lithium storage of hollow carbon involves Li+ adsorption in the defect sites and Li+ insertion. The results showed that the intrinsic structure of lotus root can inspire us to prepare biomass carbon with a hollow structure as an excellent anode for lithium-ion batteries.
