摘要
A rechargeable magnesium ion electrochemical cell comprising an anode, a cathode, and a non-aqueous magnesium electrolyte disposed between the anode and the cathode is described herein. The cathode comprises a redox-active anthraquinone-based polymer comprising one or more of 1,4-polyanthraquinone or 2,6-polyanthraquinone. Both 2,6-polyanthraquinone and 1,4-polyanthraquinone can operate with 1.5-2.0 V with above 100 mAh/g capacities at a reasonable rate, higher than the state-of-the-art Mg—Mg6S8 battery. More than 1000 cycles with very small capacity loss can be realized.
