    • All-soluble all-iron aqueous redox-flow battery 

      Gong, Ke; Xu, Fei; Grunewald, Jonathan B.; Ma, Xiaoya; Zhao, Yun; Gu, Shuang; Yan, Yushan (American Chemical Society, 2016-07)
      The rapid growth of intermittent renewable energy (e.g., wind and solar) demands low-cost and large-scale energy storage systems for smooth and reliable power output, where redox-flow batteries (RFBs) could find their ...
    • Exploiting immiscible aqueous-nonaqueous electrolyte interface toward a membraneless redox-flow battery concept 

      Gong, Ke; Xu, Fei; Lehrich, Michael G.; Ma, Xiaoya; Gu, Shuang; Yan, Yushan (Electrochemical Society, Inc., 2017-08-30)
      A new concept of membraneless battery based on immiscible aqueous and nonaqueous stratified-electrolytes was studied in a static cell for the purpose of constructing a redox flow battery (RFB). By selectively dissolving ...
    • Iodine Redox-Mediated Electrolysis for Energy-Efficient Chlorine Regeneration from Gaseous HCl 

      Zhao, Yun; Gu, Shuang; Gong, Ke; Zheng, Jie; Wang, Junhua; Yan, Yushan (Electrochemical Society, Inc., 2017-05-05)
      Hydrogen chloride (HCl) by-product is often produced from chlorine-consuming processes. Traditional electrochemical processes for converting HCl to chlorine (Cl-2) are completed by anodic oxidation reaction coupled with ...
    • Low-voltage gaseous HCl electrolysis with an iron redox-mediated cathode for chlorine regeneration 

      Zhao, Yun; Gu, Shuang; Gong, Ke; Zheng, Jie; Wang, Junhua; Yan, Yushan (John Wiley & Sons, Inc., 2017-08-28)
      Gaseous HCl as a by-product is often produced from chlorination processes using Cl-2 gas. Onsite Cl-2 regeneration from HCl is highly desirable as it eliminates the need to buy new Cl-2 and dispose HCl waste. A gaseous HCl ...
    • A new alkali-stable phosphonium cation based on fundamental understanding of degradation mechanisms 

      Zhang, Bingzi; Kaspar, Robert B.; Gu, Shuang; Wang, Junhua; Zhuang, Zhongbin; Yan, Yushan (John Wiley & Sons, Inc., 2016-09-08)
      Highly alkali-stable cationic groups are a critical component of hydroxide exchange membranes (HEMs). To search for such cations, we studied the degradation kinetics and mechanisms of a series of quaternary phosphonium ...
    • Relating alkaline stability to the structure of quaternary phosphonium cations 

      Zhang, Bingzi; Long, Hai; Kaspar, Robert B.; Wang, Junhua; Gu, Shuang; Zhuang, Zhongbin; Pivovar, Bryan; Yan, Yushan (Royal Society of Chemistry, 2018-07-25)
      Alkali-stable quaternary phosphonium (QP) is a type of cationic group for hydroxide exchange membranes (HEMs). To elucidate the relationship between structure and alkaline stability, we investigated the kinetics and ...
