Abstract: Poly(1-aminoanthraquinone) is synthesized by chemical method and used as positive electrode in rechargeable lithium battery. Using the techniques of infrared (IR) spectrum, scan electronic microscopy (SEM), granularity, cyclic voltammograms (CVs) and charge-discharge, the function group, microscopic structure, particulate size and the electrochemical performance of the polymer are studied and analyzed. When used in lithium second battery with lithium, the initial discharge capacity of poly(1-aminoanthraquinone) is 218.3 mAh•g－1,it can keep excellent cycle efficiency after 25 charge-discharge cycles. In virtue of its high energy density and good cycling capability, the poly (1-aminoanthraquinone) is a promising positive electrode material for lithium secondary battery.

Key words: Poly(1-aminoanthraquinone), Positive electrode material, Charge-discharge, Cycle, Lithium secondary battery
