The escalating demand for sustainable and efficient energy storage solutions has catalyzed the exploration of advanced materials and technologies in battery systems. Deep Eutectic Solvents (DES), a novel class of ionic liquids, have emerged as promising candidates due to their unique physicochemical properties, including low volatility, high thermal stability, and tunable solvation capabilities. This paper investigates the roles of DES in enhancing the performance and sustainability of batteries, particularly focusing on lithium-ion and sodium-ion technologies. DES-based electrolytes offer significant advantages, such as improved ionic conductivity and enhanced electrochemical stability, which are critical for the longevity and efficiency of battery systems. Furthermore, the eco-friendly nature of DES, derived from biodegradable and non-toxic components, aligns with the overarching goal of developing green and sustainable energy storage solutions. This study synthesizes recent advancements in DES research, evaluates their practical applications in current battery technologies, and discusses future directions for integrating DES in next-generation energy storage systems. The findings underscore the potential of DES to revolutionize battery technology, contributing to a sustainable energy future through enhanced battery performance and reduced environmental impact.

Iron oxide nanoparticles synthesized from plant materials have garnered considerable attention due to their environmentally friendly nature and wide-ranging applications in various fields. These NPs possess unique attributes, including biocompatibility, low toxicity, catalytic capabilities, and intricate reaction mechanisms, making them highly desirable for diverse biomedical uses. This study presents an innovative green synthesis approach for utilizing the fruit extract of Vicia faba (V. faba). The synthesized NPs underwent comprehensive characterization using advanced techniques such as Fourier-transform infrared spectroscopy (FTIR), UV-visible spectrophotometry, X-ray diffractometry (XRD), and Scanning Electron Microscope-Energy Dispersive X-ray (SEM-EDX). Notably, the V. faba fruit extract served as an effective reducing agent, facilitating the synthesis of Iron oxide nanoparticle (IONP) with well-defined structural and chemical properties. The size of Iron oxide nanoparticles falls between the range of 299.3-527.4 nm. Furthermore, the synthesized Iron oxide nanoparticles were evaluated for their antioxidant activity, revealing promising results against 2,2-diphenyl-1-picrylhydrazyl DPPH and 2,2’-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) ABTS radicals. These findings highlight the significance of V. faba fruit extract in producing IONPs endowed with valuable bioactive properties, offering considerable potential for applications in biomedicine and beyond.
