Electrochemistry involving superconcentrated electrolytes has rapidly gained attention as a transformative approach in electrochemical processes. Superconcentrated electrolytes have emerged as a groundbreaking solution in electrochemical applications, recognized for their nonflammable nature, ecofriendly composition, and expanded electrochemical stability window compared to conventional dilute aqueous electrolytes. The electrochemical hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) are fundamental processes in energy conversion and storage technologies. This study investigates the electrochemical activity of platinum electrodes in lithium-based electrolytes for understanding the electrochemical characteristics from low to high concentration. The HER and OER kinetics in superconcentrated electrolytes were performed to address challenges related to stability and efficiency in high-concentration ionic environments. Highly concentrated electrolytes characterized by their unique solvation structure and extended electrochemical stability potential window offer promising avenues for enhancing energy storage and conversion applications. Through cyclic voltammetry and linear sweep voltammetry, we analyze key parameters such as redox reactions, overpotentials, and kinetic reactions. This study explores the interaction between platinum and highly concentrated aqueous electrolytes to elucidate its influence on catalytic performance. The results provide insights into optimizing platinum-based electrocatalysis for next-generation sustainable energy solutions, highlighting the role of electrolyte composition in dictating reaction kinetics, potential window, and overall electrochemical performance.
