Cover Story: This study introduces an innovative method for recycling lithium from spent LiFePO4 batteries and repurposing the recovered lithium carbonate (Li2CO3) as a carbon dioxide (CO2) absorber. The recycling process involves dismantling the battery packs, separating the active materials, and chemically treating the cathode to extract lithium ions, producing Li2CO3. Once recovered, Li2CO3 can be utilized for capturing CO2 in hydrogen purification processes, reacting with CO2 to form lithium bicarbonate (LiHCO3). The LiHCO3 can then be thermally decomposed to regenerate Li2CO3, ensuring the cyclic and sustainable use of the material. This dual-purpose process not only addresses the environmental impact of LiFePO4 battery disposal but also contributes to CO2 reduction. Utilizing recycled Li2CO3 decreases the demand for virgin lithium extraction, supporting a circular economy.
