Abstract
The invention provides a waste lithium battery treatment method which comprises the following steps: crushing a waste battery; removing electrolyte; removing irony metal through magnetic separation; dissolving surplus scrap materials of the treated battery into hydrochloric acid; adding hydrogen peroxide to promote dissolving; filtering the above dissolving solution to obtain a solution containing metal ions; carrying out electrolytic deposition on the obtained solution containing the metal ions step by step to obtain zinc and manganese dioxide; and finally extracting other metals by adopting ion exchange resin.
Description
Technical field
The invention belongs to the solid waste process field, be specifically related to the method that a kind of waste lithium cell is innoxious, resource recycles.
Background technology
The environmental type energy products that lithium ion battery is earned foreign exchange as high-tech, high production, high profit, height are referred to as one of one of large high-tech of 21 centurys ten or ten large money-making industries by external expert.In addition, along with the electronic product consumption increases day by day, its consumption figure is just with at double speed increment.And along with the development of lithium ion battery industry, its cost reduces gradually, and lithium battery is expected to occupy whole world Battery Market lion's share, is used widely.In the U.S., chargeable lithium cell accounts for 11% of U.S.'s lithium consumption figure with the lithium amount, and Japanese chargeable lithium cell accounts for 54% of Japanese lithium consumption figure with the lithium amount, and lithium battery has surpassed ickel-cadmium cell and Ni-MH battery aspect sale.
The negative material that uses in the lithium ion battery mostly is graphite, and positive electrode is then for the embedding lithium transition-metal oxide, and such as LiCoO2, LiNiO2, LiVO2 and LiMn2O4 etc., wherein using maximum is LiCoO2.In addition, along with to the going deep into of anode material for lithium-ion batteries research, people mix a small amount of nickel in LiCoO2, are used for the production of lithium ion battery as positive electrode with their mixed oxide.
Contain a large amount of expensive metallic cobalts in the waste and old lithium ion battery.Cobalt is a kind of rare precious metal, content in various ore deposits is very low, resource scarcity, and metal recovery rate is low in the production process, complex process, production cost is high, its content in lithium ion battery is then relatively high, if the cobalt resource in the waste and old lithium ion battery can be recycled, no matter is from the environmental protection aspect, or the recycling aspect of resource all is significant.
Summary of the invention
The object of the present invention is to provide a kind of recycling processing method of waste lithium cell, adopt the dissolving with hydrochloric acid battery waste, and to wherein adding hydrogen peroxide to promote the dissolving of metal in acid, the metal maximization in the refuse battery is reclaimed.
For reaching above-mentioned wood, the present invention adopts following technical scheme:
The waste lithium cell processing method, adopt following method:
(1) refuse battery is broken: refuse battery is broken, remove electrolyte, and remove ferrous metal by magnetic separation again;
(2) dissolving: the remaining power waste material after step (1) processing is dissolved in the hydrochloric acid, and adds hydrogen peroxide promotion dissolving;
(3) filter: the lysate of filtration step (2) obtains the solution of metal ion;
(4) ion-exchange: adopt the metal in ion exchange resin extraction step (3) the gained solution.
In the technical scheme provided by the invention, the described concentration of hydrochloric acid of step (2) is 6mol/L; The mass ratio of the described battery waste of step (2) and hydrochloric acid is 1:3 ~ 5.
In the technical scheme provided by the invention, the addition of the described hydrogen peroxide of step (2) is 12 ~ 18wt% of battery waste.
For the metal in the battery waste better is dissolved in the hydrochloric acid, the present invention adds hydrogen peroxide in the process of dissolving.The adding of hydrogen peroxide not only promotes the dissolving of metal in hydrochloric acid, and makes the process of dissolving also can obtain very high dissolution rate at normal temperatures.In addition, the present invention continues other heavy metal ion is extracted by ion exchange resin, has reduced to greatest extent the pollution of heavy metal to environment, and heavy metal ion has been realized recovery.
