Sammanfattning
The project is an evaluation of a recycling process of lithium batteries using a hydrometallurgical treatment method. The focus in this study was to investigate the effect of several parameters on the leaching process. The studied parameters were: acid concentration, temperature and solid to liquid ratio. A kinetic study was performed as well. The work started with theoretical studies to collect information about lithium-ion batteries in general and existing technologies which are used for the recycling. The work continued with experimental studies. The electrodes recovered from the lithium-ion battery were crushed. The black mass was then leached with sulphuric acid. Several parameters such as different temperature, acid concentration, time and solid to liquid ratio were studied.
