From green cathode material to sustainable energy technology: A holistic approach
This study presents the development and preliminary evaluation of aqueous lithium-ion battery (ALIB) systems, employing LiFePO₄ (LFP) cathodes paired with Li₄Ti₅O₁₂ (LTO) anodes. ALIBs represent a promising alternative to traditional lithium-ion batteries due to improved safety, enhanced ionic conductivity, reduced environmental impact, and lower production costs. To support sustainability, nickel-plated aluminum current collectors were employed to improve conductivity and electrode adhesion. LiFePO₄ cathodes synthesized under optimized conditions exhibited crystallinity and uniform morphology, as verified by X-ray diffraction (XRD) and scanning electron microscopy (SEM). Spray deposition was found to be an effective method for preparing stable cathode layers with potential for scalability. Electrochemical evaluations demonstrated that the pairing of an LFP cathode with an LTO anode in an aqueous system, reported for the first time, exhibited stable cycling behavior and coulombic efficiency. These findings mark an important step forward in advancing environmentally sustainable and scalable aqueous lithium-ion energy storage solutions.
