摘要
Abstract
Water-soluble binder carboxymethyl cellulose sodium(CMC) was synthesized by slurry process. The Fourier transform infrared(FT-IR),nuclear magnetic resonance(1H-NMR)and SEM analyses were taken.The 9,10-anthraquinone( AQ)electrodes was tested by galvanostatic discharge-charge,cyclic voltammetry and electrochemical impedance spectroscopy. The specific capacity and cycle performance of electrode using CMC as binder was higher than the one using PVDF. When cycled with the current density of 0.2 mA/cm2 in 1.5～3.5 V,the specific discharge capacity of AQ/CMC-1 electrode which was prepared with the binder CMC-1 which had high degree of substitution(DS= 1.23)in the initial and 50th cycle was 226.4 mAh/g and 70.9 mAh/g, respectively. The electrochemical performance of CMC-1, which had a higher DS was superior to CMC-2 with a lower DS(DS= 0.86). 关键词
