Lithium refinery residue reuse in construction materials production: Status, challenges and further perspectives.

With the booming of rechargeable battery production for energy transition to a cleaner pattern, more lithium refinery residues (LRRs) are being generated and feasible ways to LRRs consumption must be found. In this work, recent advances in utilizing LRRs for fabrication of cement, concrete and geopolymer as well as some other applications, are critically reviewed. It is demonstrated that LRRs contain a significant number of micro-fine particles and are abundant in silica and alumina contents.

Leaching Li from mixed cathode materials of spent lithium-ion batteries carbon thermal reduction.

The use of a carbon thermal reduction roasting method to recover lithium resources from spent lithium-ion batteries (S-LIBs) provides an important opportunity for recycling S-LIBs. The preferential extraction of Li reduction roasting has been widely studied; however, the extraction of Li from mixed cathode materials has been rarely reported. Herein, we propose a method based on carbon thermal reduction to preferentially extract Li from mixed cathode materials.
