    • Alkaline Benzoquinone Aqueous Flow Battery for Large-Scale Storage of Electrical Energy 

      Yang, Zhengjin; Tong, Liuchuan; Tabor, Daniel; Beh, Eugene; Goulet, Marc-Antoni; De Porcellinis, Diana; Aspuru-Guzik, Alán; Gordon, Roy; Aziz, Michael
      An aqueous flow battery based on low-cost, nonflammable, noncorrosive, and earth-abundant elements is introduced. During charging, electrons are stored in a concentrated water solution of 2,5-dihydroxy-1,4-benzoquinone, ...
    • Alkaline Quinone Flow Battery with Long Lifetime at pH 12 

      Kwabe, David G.; Ji, Yunlong; Lin, Kaixiang; Kerr, Emily F.; Goulet, Marc-Antoni; De Porcellinis, Diana; Tabor, Daniel P.; Pollack, Daniel A.; Aspuru-Guzik, Alán; Gordon, Roy; Aziz, Michael (Elsevier BV, 2018-09)
      We demonstrate a long-lifetime, aqueous redox-flow battery that can operate at a pH as low as 12 while maintaining an open-circuit voltage of over 1 V. We functionalized 2,6-dihydroxyanthraquinone (2,6-DHAQ) with highly ...
    • Extending the Lifetime of Organic Flow Batteries via Redox State Management 

      Goulet, Marc-Antoni; Tong, Liuchuan; Pollack, Daniel; Tabor, Daniel P.; Odom, Susan A.; Aspuru-Guzik, Alán; Kwan, Eugene; Gordon, Roy; Aziz, Michael (American Chemical Society (ACS), 2019-04-26)
      Redox flow batteries based on quinone-bearing aqueous electrolytes have emerged as promising systems for energy storage from intermittent renewable sources. The lifetime of these batteries is limited by quinone stability. ...
    • Flow Batteries: Alkaline Benzoquinone Aqueous Flow Battery for Large-Scale Storage of Electrical Energy 

      Yang, Zhengjin; Tong, Liuchuan; Tabor, Daniel; Beh, Eugene S.; Goulet, Marc-Antoni; De Porcellinis, Diana; Aspuru-Guzik, Alan; Gordon, Roy Gerald; Aziz, Michael J. (Wiley-Blackwell, 2018)
      We introduce an aqueous flow battery based on low-cost, non-flammable, non-corrosive and Earth-abundant elements. During charging, electrons are stored in a concentrated water solution of 2,5-dihydroxy-1,4-benzoquinone ...
