| Abstract |
A redox flow battery (RFB) is one of the most promising technologies for large-scale energy storage system. It stores its energy in the redox-active materials dissolved in liquid electrolytes by utilizing the redox chemistry for energy conversion between electrical energy and chemical energy. It has some advantages: independent design of the power and energy capacity, high capacity, and long cycle life. But conventional aqueous flow batteries have low energy density due to the limited cell voltage (<1.8 V). So recent research efforts have focused on identifying various organic systems which enable high cell potentials (>2.5 V) and energy densities. Here we showed the improved electrochemical properties by utilizing organic radical active materials which can have high solubility, chemical stability leading to the high energy density, cell voltage and cycle stability. |
