Abstract |
It is very important to recycle the waste biomass resources for the environment protection and the circular economy. For this purpose, the waste old loofah was carbonized at 800 degrees C for 1 h in the inert nitrogen gas (N-2) atmosphere for lithium ion battery anode. The resultant waste-loofah-derived carbon was investigated by scanning electron microscopy, energy dispersive X-ray spectroscopy, Fourier transform infrared spectroscopy, X-ray diffraction, nitrogen adsorption and desorption, galvanostatic charge/discharge, cyclic voltammetry and alternating current impedance. The results suggested that the waste-loofah-derived carbon powders consisted of many concomitant microparticles and nanoparticles with a specific surface area of about 492m(2)/g. Furthermore, the waste-loofahderived carbon anode also delivered high electrochemical lithium (Li) storage activity. For example, the initial specific discharge capacity was about 697 mAh/g, and the reversible discharge capacity was about 187 mAh/g at 1000 mA/g for 500 cycles and still about 98 mAh/g even at 3000 mA/g for 500 cycles, exhibiting good cycling stability. High surface area and structural defects may jointly contribute to high electrochemical performances. |
