Spent batteries, which are omnipresent in modern life, have a dual challenge: disposal causes environmental damage, but recycling offers a transformational alternative. Battery recycling is a critical step towards more sustainable resource management. Recycling not only conserves resources, but also reduces the need for dangerous mining operations by preserving important elements like lithium, cobalt, and nickel. This strict recycling strategy dramatically decreases carbon footprint, promoting a circular economy in which materials are used rather than discarded. Nonetheless, life cycle assessment (LCA) is an effective method for guiding the development of higher-performing batteries with a lower environmental impact. This study investigates typical procedures in lithium-ion battery life cycle assessments and gives recommendations for future studies that are more interpretable, representative, and effective. Proper disposal keeps hazardous compounds from seeping into the environment, decreasing soil and water contamination. However, challenges persist, including technological limitations, cost-effectiveness, and the global demand for standard recycling methods. Increased public awareness and concerted efforts among businesses, governments, and consumers are necessary to optimize the environmental benefits of battery recycling, assuring a brighter future for future generations.
