Efficient Recycling of Spent LiCoO2 Cathodes Via Confined Pore‐Assisted Simplified Direct Carbothermic Reduction Without External Reducing Agents

open access: yesENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 2, March 2026.
A simplified direct carbothermic reduction (SDCR) process is developed for efficient recycling of spent LiCoO2 cathodes. The SDCR method employs carbon conductive agents and organic binders embedded in the electrode as internal reducing agents, while the confined pores of calendered electrodes promote the retention of in situ generated reduction gases.

Advances in Hydrometallurgy [PDF]

open access: yes, 2020
The development of new technologies and the increasing demand for mineral resources from emerging countries are responsible for significant tensions in the pricing of non-ferrous metals. Some metals have become strategic and critical because they are used in many technological applications such as flat panel TVs (indium), solar panel cells (indium ...

Lanthanum biosorption by different Saccharomyces cerevisiae strains [PDF]

open access: yes, 2016
Biosorption can be a promising technology in rare earth metal separation and recovery due to the low costs of waste biomasses (used as biosorbents) and the high selectivity exploiting specific interaction between metals and biological active sites.

Advanced Characterization and Rejuvenation of End‐Of‐Life Lithium‐Ion Anodes: Toward the Development of a Green Upcycling Route

open access: yesSmall, Volume 22, Issue 14, 6 March 2026.
Green solvents (DI water or ascorbic acid) enable the regeneration of end‐of‐vehicle‐life battery anodes without delamination and re‐manufacture. Multimodal characterizations reveal several graphite microstructures and crystallography, and restored cycling performance.

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

open access: yesArchives 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 ...

Iron‐Based Materials for Advanced Lithium/Sodium‐Ion Batteries

open access: yesChemSusChem, Volume 19, Issue 4, 25 February 2026.
This Review examines iron‐based anode materials for lithium‐ and sodium‐ion batteries, emphasizing how phase chemistry (sulfides, oxides, and metal–organic framework (MOF)‐derived compounds), multiscale structural engineering, and interface regulation collectively address volume expansion, conductivity limitations, and cycling instability, while ...
