Pretreatment, the initial step in recycling spent lithium-ion batteries (LIBs), efficiently separates cathode and anode materials to facilitate key element recovery. Despite brief introductions in existing research, a comprehensive evaluation and comparison of processing methods is lacking.
6. Conclusion Pretreatment is the first step in the recycling of spent LIBs, which is aimed at efficiently sorting various battery components to simplify the subsequent material recycling process, reduce chemical usage, and improve recycling efficiency.
The process of recycling used lithium-ion batteries involves three main technology parts: pretreatment, material recovery, and cathode material recycling. Pretreatment includes discharge treatment, uniform crushing, and removing impurities.
Battery recycling is a downstream process that deals with end-of-life batteries of different types and health conditions. Many established battery-recycling plants require a standardized presorting process to distinguish spent LIBs, as direct recycling reduces the efficiency of recovering valuable metals.
The review concludes that hydrometallurgy might be the most efficient method of recycling waste LIBs on an industrial scale. Recently, the demand for lithium-based battery-operated electronics, solar panels, e-scooters and, most importantly, electric vehicles (EVs), has increased.
