氨基蒽醌衍生物的合成及其用作锂电池正极材料的电化学性能
Preparation and Electrochemical Performance of Aminoanthraquinone Derivative as Cathode Materials in Rechargeable Lithium Batteries
摘要
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.关键词
