摘要：Sisal is a perennial tropical biomass with largest dosage in industry. Due to the special hard structure of sisal fiber, it can be prepared as carbon material and applied for negative material of lead-carbon battery. The pretreatment of sisal fiber was carried out by 5% NaOH and 5% H3PO4 and tested by the measurement of FTIR, thermogravimetric analysis and SEM. Carbazole was doped in pretreated sisal fiber to prepare carbon material by a simple approach with two-step method. The characterization of the synthesis doped-N carbon material was tested by Raman, BET, XRD and EDS. According to the result of BET, it was turned out that the doped-N carbon material had a larger specific surface area. And the electrochemical properties were measured by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). Besides, the cycling life test and charge/discharge curve were performed on battery testing instrument. In addition, the lead-carbon battery contained doped-N carbon material had a longer discharge plateau and a higher ultimate capacity. It was concluded that doped-N carbon material had a better electrochemical performance compared to undoped-N carbon material. (C) 2018 Elsevier Ltd. All rights reserved.
