As cobalt is a strategic metal essential for the energy and digital transition, the current research work focuses on cobalt recovery from Li‐ion batteries by precipitation. Simulation results allow determination of the cobalt hydroxide precipitation conditions for a complete cobalt recovery. The experimental results show the high impact of temperature on cobalt hydroxide precipitation kinetics and on particle size distribution. Indeed, cobalt recovery is optimal at 25 °C, with a yield of nearly 100 %. However, the simulation results show that it is necessary to be careful about the chosen temperature to avoid coprecipitation of cobalt with manganese. These promising results allow a better understanding of cobalt hydroxide precipitation for a complete recovery from Li‐ion battery leachates.
