An Integrated Chemicals‐Free Circular Model for Lithium Recovery From Spent Batteries to Direct Lithium Extraction From Brines

Battery Energy, Volume 5, Issue 3, May 2026.
A simple, chemical‐free method based on a 5‐min microwave treatment and using only water enables the synthesis of Li/Al layered double hydroxides (LDHs) from waste lithium‐ion batteries. These Li/Al LDHs can then be used for lithium extraction from primary resources, supporting a truly sustainable circular economy for lithium.
