Abstract: The present invention relates to a method of simultaneously recovering cobalt (Co) and manganese (Mn) from lithium-based BATTERY, and more particularly, to a method that is capable of simultaneously recovering cobalt and manganese from lithium-based BATTERY, i.e., recycled resources that contain large amounts of cobalt and manganese, with high purities using multistage leaching and electrowinning methods. According to the method of the present invention, cobalt and manganese can be simultaneously recovered from lithium-based BATTERY as recycled resources, and a recovery method that is cost-effective compared to conventional methods can be provided.
