Batteries waste is found anywhere in the world because most of the electronic devices use batteries to operate them. Batteries that were used for electronic devices nowadays is lithium ion batteries. Lithium ion batteries is one of the rechargeable batteries where it contained heavy metals which is very dangerous for health and environment. However, in order to minimalize the composition before its being disposed many researchers have found a way to recover heavy metals, because it can be useful to reproduce lithium ion batteries in the future. In this research, hydrometallurgical leaching process has been done for recovery cobalt from used lithium ion using hydrogen peroxide as reducing agent and citric acid as a leaching agent by varying citric acid concentration (0-2 M), reaction temperature (50-80°C), and reaction time (5-60 minutes). The result were analyzed by atomic absorption spectroscopy (AAS) and showed that the best operation condition is at concentration 1 M, temperature 80oC with stirring time 60 minutes can recover more than 90% of Cobalt.
