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%.
A flow battery is an electrochemical battery, which uses liquid electrolytes stored in two tanks as its active energy storage component.
The major characteristic and benefit flow batteries is the decoupling by design of power and energy. Power is determined by the size and number of cells, energy by the amount of electrolyte. Their low energy density makes flow batteries unsuited for mobile or residential applications, but attractive on industrial and utility scale.
The battery with gel polymer electrolyte exhibits capacity retentions of 96.8% and 78.8% and Coulombic efficiencies of 97.8% and 98.4%. These results highlight the polymer electrolyte strategy’s potential for enhancing battery performance and safety. Nonaqueous redox flow batteries face challenges like costly membranes and unstable electrolytes.
