Nonaqueous redox flow batteries face challenges like costly membranes and unstable electrolytes. Here, authors develop a membrane-free battery using a polypropylene carbonate gel polymer electrolyte with Li anode and Tri-TEMPO catholyte, achieving a high voltage of 3.45 V, capacity retention of 96.8%, and efficiency of 98.4%.
