Efficient energy storage is crucial for integrating renewable energy sources and ensuring climate security. Redox flow batteries (RFBs) offer a scalable solution but are currently hindered by high costs and limited ion exchange membranes. To address these limitations, biphasic membrane-free redox flow batteries (RFBs) have received significant attention. However, it is important to note that this membrane-free technology is still in its early research stages and presents several challenges such as self-discharge, low Coulombic efficiency, and reduced state of charge. To address this, hybrid Zn-based biphasic membrane-free RFBs have emerged as a potential solution. These systems utilize a metal-based anolyte (Zn metal anode) that remains separate from the catholyte, thereby mitigating self-discharge and enhancing coulombic efficiency. However, existing hybrid Zn-based membrane-free RFBs predominantly use aqueous electrolytes for the Zn metal anode. This approach presents several issues, including dendrite formation, undesired side reactions such as hydrogen and oxygen evolution, a restricted voltage window, and surface passivation problems. To overcome these challenges, this research proposes the development of a hybrid Zn-based membrane-free RFB utilizing a nonaqueous biphasic electrolyte system. By employing a eutectic solvent for the Zn metal anode and a nonaqueous solvent for the redox-active cathode materials, this approach aims to reduce dendrite formation, eliminate unwanted side reactions, and extend the electrochemical stability window. This innovative system promises to enhance both efficiency and energy density, addressing the limitations of both aqueous and nonaqueous systems. Conducted at IMDEA Energy under the guidance of Dr. Rebeca Marcilla, the project will focus on developing advanced electrolytes, fabricating the biphasic system, designing high-voltage batteries, and evaluating performance.
