摘要： 合成了两种新型的有机正极材料——5-氨基-2,3-二氢-1,4-二羟基蒽醌(ADDAQ)和5-氨基-1,4-二羟基蒽醌(ADAQ), 用核磁氢谱(1H-NMR)、质谱(MS)、元素分析(EA)、傅里叶红外(FTIR)光谱、紫外-可见(UV-Vis)光谱等方法对材料进行了表征, 应用恒流充放电(GD/C)、循环伏安法(CV)、交流阻抗(EIS)等测试手段对材料的电化学性能进行了测试. 实验结果表明: 相比ADDAQ, ADAQ首次放电容量和循环性能都有显著提高. ADAQ的首次放电比容量为185 mAh·g-1, 50次循环之后容量为93 mAh·g-1. 并讨论了ADDAQ和ADAQ电化学性能差异的原因.

Abstract: Two novel organic compounds, 5-amino-2,3-dihydro-1,4-dyhydroxy anthraquinone (ADDAQ) and 5-amino-1,4-dyhydroxy anthraquinone (ADAQ), were synthesized as cathode materials for lithium batteries. The compounds were characterized by 1H nuclear magnetic resonance (1H NMR) spectroscopy, mass spectrometry (MS), elemental analysis (EA), Fourier transform infrared spectroscopy (FTIR), ultraviolet-visible (UV-Vis) spectroscopy. The electrochemical performance of the compounds was investigated by galvanostatic discharge/charge (GD/C) measurements, cyclic voltammetry (CV), and electrochemical impedance spectrum (EIS). Compared with ADDAQ, the initial discharge specific capacity and cycle performance of ADAQ were effectively improved. The initial discharge specific capacity of ADAQ was 185 mAh·g-1, after 50 cycles, the specific capacity was maintained at 93 mAh·g-1. A reason for this improvement is discussed.
