ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.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.

Process and model of a chemically buffered supported liquid membrane system for cobalt extraction
Journal of Chemical Technology &Biotechnology, EarlyView.Abstract BACKGROUND Cobalt is a valuable metal whose total annual supply from recycling is projected to be 34 000 t by 2030, primarily from batteries. Supported liquid membrane (SLM) technology is emerging as a promising technology alternative to conventional hydrometallurgy for cobalt recovery.
