| titleOfInvention | A method for recovering lithium carbonate from NCM111 positive electrode material of waste ternary lithium ion battery |
| abstract | A method for recovering lithium carbonate from the NCM111 positive electrode material of a waste ternary lithium ion battery relates to a method for recovering lithium carbonate from the positive electrode material of a waste ternary lithium ion battery. The invention aims to solve the problem that the existing method for regenerating the NCM111 waste material of the positive electrode material of ternary lithium ion battery causes serious secondary pollution to the atmospheric environment and water environment, high requirements for the anti-corrosion performance of the recycling equipment, and high regeneration cost. , The technical problems of low added value of recycled products and high energy consumption in the regeneration process. In the present invention, waste NCM111 is mixed with sodium chloride and then hydrothermally reacted, the reaction product is filtered, the filtrate is evaporated and concentrated, sodium carbonate solution is added for heating to precipitate lithium, and the filter residue obtained by filtration is lithium carbonate. The invention has the advantages of low regeneration cost, easy operation, low requirements for equipment anticorrosion, the recovered lithium carbonate has a purity of up to 95%, the lithium ion recovery rate reaches 80%, and no secondary pollution is generated during the recovery process. The present invention is applied to the recovery of lithium carbonate. |
