Polyanthraquinone-based organic cathode for high-performance rechargeable magnesium-ion batteries

Patent Liao, Chen; Pan, Baofei; Burrell, Anthony

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.

Non-aqueous electrolyte for high voltage rechargeable magnesium batteries

Patent Doe, Robert Ellis; Lane, George Hamilton; Jilek, Robert E; ...

An electrolyte for use in electrochemical cells is provided. The properties of the electrolyte include high conductivity, high Coulombic efficiency, and an electrochemical window that can exceed 3.5 V vs. Mg/Mg.sup.+2. The use of the electrolyte promotes the electrochemical deposition and dissolution of Mg without the use of any Grignard reagents, other organometallic materials, tetraphenyl borate, or tetrachloroaluminate derived anions. Other Mg-containing electrolyte systems that are expected to be suitable for use in secondary batteries are also described.
