Abstract
The invention discloses a method for reclaiming valuable metals from waste lithium batteries, which comprises the following steps of: crushing discharged waste lithium batteries, calcining at the high temperature of 350-400 DEG C to obtain a material containing cobalt, copper and aluminum, adding 5-10% sodium hydroxide solution to the material, making the sodium hydroxide solution react with the material for 2-3 hours, filtering alkaline liquor, washing and drying to obtain a material containing cobalt and copper; adding sulfuric acid with a certain concentration and Na2S2O3 to the material containing cobalt and copper, mixing, dissolving, adding an extractant to extract copper, and adding an extractant to the copper-extracted solution to extract cobalt. The method is simple and effective and has low reclamation cost.
Description
Technical field
The present invention relates to recycling, particularly from waste lithium cell, reclaim the method for valuable metal from waste lithium cell.
Background technology
Lithium ion battery has been widely used in the portable type electronic product field since 20th century, entered commercialization the nineties.But lithium ion battery is after using after a while, and electrode materials can expand, shrink, even the performance of active substance also will change, and cause the decline of cell container, even battery is scrapped.In recent years, along with lithium ion battery applications more and more widely, the battery consumption increases rapidly, the lithium ion battery of scrapping also will increase year by year significantly.After the lithium ion battery of these tons oves is scrapped, can produce serious potential safety hazard and environmental pollution if deal with improperly, also can cause the great wasting of resources simultaneously, along with the positive development of society and the people pay attention to day by day to environmental protection, the recovery of waste and old lithium ion battery will become very urgent problem.
Contain the multiple precious metal that recovery value is arranged in the lithium ion battery, as cobalt, copper, lithium, aluminium etc., therefore, the recycling lithium ion battery has bigger economic worth, but at present also not simply, recovery and treatment method efficiently.
