The widely recognized theory states that ions rearrange themselves around charged surfaces in an electrolyte to form the structure known as the electrical double layer (EDL). This structure fluctuates with the electrode voltage and is distinct from the electrolyte's bulk composition. The electric double layer effect is significant in the storage of lithium ions in batteries, and improving recycling methods to maintain the integrity of these layers is a major area of research. Some techniques involve using solvents or advanced materials to break down battery components while preserving the reliability of the electric double layer for potential reuse. When batteries are taken apart for recycling, there is a risk of disrupting the electric double layer structure, which can become contaminated with impurities and degradation products, and the electrodes may experience physical and chemical alterations. To address these challenges and issues related to the electric double layer effect in battery recycling, innovative recycling technologies, quality control measures, and a comprehensive understanding of the electrochemical processes involved are required. Solar power is one of the clean, renewable energy sources that contemporary civilization needs more have because of the depletion of fossil fuels and their detrimental effects on the environment. Energy may be saved by switching from fossil fuels to renewable energy sources, which can help streamline the distribution of energy by moving electrons across grids. This review paper discusses the EDL effect, its importance in battery recycling, its influence on energy storage technologies, electrochemical capacitors, battery recycling techniques, factors that affect EDL capacitance, and how the EDL behaves during charging and discharging cycles. Consequently, this paper provides insights into future challenges in battery recycling related to battery materials and chemical compositions, as well as potential strategies and approaches to tackle these challenges.
