Toward Sustainable Spent Cathode Recycling Technology: Failure Mechanism, Advancing Technology and Prospect

Rare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT The cathode materials from spent batteries are expected to become a resource stream rich in critical metals, drawing increasing attention to the disposal and recycling of spent lithium‐ion batteries (LIBs). However, due to current technological limitations, the recycling efficiency and environmental sustainability of LIBs still face ...

Electrochemical Lithium‐Ion Recovery from Battery Recycling Process Water

ChemSusChem, Volume 19, Issue 8, 28 April 2026.
A high‐purity Lithium‐ion solution was recovered by implementing a simple two‐step process combining the wet‐shredding of spent Lithium‐ion batteries with efficient electrochemical desalination. This work provides a simple and novel approach for the electrochemical extraction of Lithium ions from spent batteries.

Behavior and Study of the Kinetics Aspects of Hydrothermal Leaching Conducted on Thermal Activated Products of Complex Polymetallic Secondary Sulfide Concentrate [PDF]

Archives of Metallurgy and Materials
The utilization of complex polymetallic secondary sulfide concentrate (CPSSC) is difficult, owing to its special structure and composition. In this paper, CPSSC was firstly activated by roasting under atmosphere, followed by hydrothermal leaching under ...

Toward 4R Electronics: Liquid‐Metal‐Enabled Thin Film, and Field‐Effect Transistors for Sustainability and E‐Waste Reduction

Advanced Materials Technologies, Volume 11, Issue 7, 6 April 2026.
The 4R principle—Resilience, Repairability, Recyclability, and Renewability—enables sustainable liquid‐metal transistors. LM materials provide stretchable, damage‐tolerant architectures, allow rapid circuit repair, permit full material recovery through dissolution, and support renewable fabrication cycles, forming a closed‐loop pathway toward ...

Engineered Biopolymer Architectures for Selective Metal Ions Extraction

Advanced Sustainable Systems, Volume 10, Issue 4, April 2026.
This review establishes a mechanism‐oriented framework that connects biopolymer chemistry, structural engineering, ligand design, and hydrometallurgical process variables for selective metal‐ion extraction. It analyzes how functional groups, hierarchical architectures, and solution speciation govern adsorption capacity and selectivity in acidic ...

Circular Potential of Lithium‐Ion Battery Recycling Slags: Quantifying Microstructure and Elemental Distribution for a Holistic Valorization

Advanced Science, Volume 13, Issue 22, 17 April 2026.
A lithium‐bearing slag is investigated with the goal of holistic valorization. The present β‐eucryptite (LiAlSiO4) exhibits a high lithium content and low levels of impurities. The spinel contains most of the chromium and vanadium, representing additional valorization opportunities.

Development of Recycling Process for Copper-Gallium Target

Journal of MMIJ, 2018
Gallium is used as a raw material for a CIGS solar cell. In the manufacturing process of CIGS solar cells, only 30% of the target material is used, and the rest is not used and becomes a spent target scrap.

Germanium and Indium Recovery from Zinc Metallurgy by-Products—Dross Leaching in Sulphuric and Oxalic Acids

Metals, 2018
Leaching of the dross containing 28.7% Sn, 18.0 Pb, 10.6% Cu, 8.9% Ge, 8.1% Zn, and 2.7% In in sulphuric and oxalic acid solution was investigated. The dross was obtained from thermal oxidation of by-product alloy generated during a New Jersey (NJ) zinc ...
