Method of recovering lithium compound from positive electrode material of spent lithium secondary battery |
| abstract |
The present invention relates to a method for recovering a lithium compound from the positive electrode material of the spent lithium secondary battery. Specifically, the recovery method includes adding a carbon-based additive to the positive electrode material separated from the spent lithium secondary battery, and thermally decomposing under an oxidizing atmosphere in the temperature range of 400 to 800 ℃; Eluting the pyrolyzed positive electrode material to obtain an aqueous solution containing a lithium compound; And concentrating the aqueous solution.n n n The method for recovering a lithium compound according to the present invention is environmentally friendly because it does not use harmful compounds such as acids, and it is economical because it does not use expensive chemicals. In particular, it is possible to recycle the lithium secondary battery mainly used in small household appliances, mobile products and hybrid electric vehicles (HEV / EV) in recent years, it can be usefully applied to the industrial field for the recycling of waste lithium secondary battery. |
