Abstract

All countries pledged to strive to limit global warming. The implementation of renewable energy must be accelerated. One of the most essential components of renewable energy is lithium-ion batteries. The surging demand for lithium necessitates new technologies for direct recovery from brine. One of the most promising methods is adsorption. Because of its advantages, lithium-aluminum layered double hydroxides have started their application on a commercial scale. This research uniquely explores the synthesis of lithium adsorbent from aluminum waste, an approach that is both cost-effective and environmentally sustainable. The reaction behavior was studied, including the rate of hydrogen gas production and the co-precipitation process. The quality of the product was assessed by its adsorption capacity and characterization. The synthesis of lithium adsorbent was successfully performed through two-step processes, with the reaction kinetics studied at temperatures between 30 and 60 °C. XRD and FTIR results confirmed the adsorbent product. The adsorbent worked well for synthetic brine with 39–1350 ppm lithium concentration and adsorption capacity until 6.7 mg lithium ion per g of adsorbent. These findings contribute to the development of sustainable technologies for lithium extraction and can be applied to improve industrial lithium recovery processes.
