The electrolyte in spent Li-ion batteries is prone to cause a high risk of hazardous emissions (HF, etc.) the state-of-the-art recycling processes. It main source fire risks and represents significant burden for recyclers due safety. Still, extended research fully recycle without its destruction at elevated temperature scarce. This study focuses on extraction from LiBs using sub- supercritical carbon dioxide fill this gap. effects critical process parameters, pressure (60–120 bar), (15–55...
Electrolyte recovery is seldomly considered in state-of-art lithium-ion battery recycling methods but rather evaporates and decomposes uncontrolled during the pre-treatment steps. However, controlled safe removal of electrolyte inevitable high importance to industry minimize environmental impact processes by preventing severe threats produced inflammable, toxic hazardous components electrolyte. This study investigated effects temperature process time a low thermal treatment on recovery. The...
Ethylene carbonate is, among other applications, used in Li-ion batteries as an electrolyte solvent to dissociate Li-salt. Supercritical CO2 extraction is a promising method for the recycling of solvents from spent batteries. To design process, knowledge solute solubility essential. In this work, ethylene at different pressure (80–160 bar) and temperature (40 °C, 60 °C) conditions studied. It shown that increased with both temperatures, ranging 0.24 8.35 g/kg CO2. The retrieved data were...
