Description
Technical field
The utility model relates to a kind of environmental protection and reclaimer, and more particularly, the utility model relates to a kind of recovery production technology and equipment that contains the aluminium waste battery.
Background technology
Lithium rechargeable battery, since nineteen ninety realizes commercially producing application, because have that volume is little, in light weight, storage electric energy power is big, charging rate fast, the serviceability temperature wide ranges, the operating time is long and longly recycle plurality of advantages such as life-span, thereby is widely used in video camera, mobile phone, notebook computer and Portable Measurement Instrument etc.
Lithium rechargeable battery, comprise the shell of metal or plastics and the electric core of content, the electricity core comprises positive pole, negative pole, barrier film, generally, positive electrode active materials is made up of about 90% cobalt acid lithium powder, the agent of 7-8% carbon black conductive, 3-4% organic bond, and positive electrode active materials is coated on the aluminium flake collector body; Negative active core-shell material is made up of about 94% carbon element powder, 5-6% organic bond, and negative active core-shell material is coated on the copper sheet collector body.Lithium ion battery can be because electrode expands, capacity descends and scraps through after the discharging and recharging of certain number of times; Also having wide variety of materials in process of production scraps.
Along with technology and expanding economy, the use amount of lithium ion battery constantly increases year by year, and the lithium ion battery of scrapping also will increase considerably year by year.With common mobile phone lithium ion battery is example, and wherein cobalt content is about 15%, and lithium content is about 0.1%, and cobalt is a heavy metal element, can cause great harm to environment.Waste and old lithium ion battery or production waste are reclaimed, not only can eliminate the pollution of harmful substance, but also can make full use of resource, thereby have important Significance for Environment and potential economic worth environment.Now, along with the environmental consciousness of entire society is strengthened gradually, and natural resources is in short supply day by day, recycles resource material in the discarded lithium rechargeable battery, reduces waste battery has caused industry day by day to the pollution of environment concern.
After with the lithium rechargeable battery broken shell, the barrier film of metal wherein, plastic casing and content is easy to adopt physical separation method such as gravity, wind-force, magnetic force to be separated and reclaims or handle; And in anode and cathode active materials wherein and aluminium flake, the copper sheet collector body: physical property such as the proportion of copper sheet collector body, mechanical tenacity and even commercial exploitation be worth with its on carbon element powder, organic bond difference bigger, thereby relatively easy separating treatment; In contrast to this, the difference of the proportion of aluminium flake collector body and even commercial exploitation value and the acid of the positive electrode active materials cobalt on it lithium powder is all less, along with the resource growing tension, positive electrode has the more and more higher market price and value, therefore, the requirement that the separation of positive electrode is reclaimed is higher relatively.
In this regard, have application number be 200510018601.6 Chinese patent application file disclose a kind of from waste and old lithium ion battery the method for separating and recovering cobalt, it is characterized in that: after waste and old cobalt acid lithium battery discharge, carry out physics and disassemble, obtain containing the positive electrode of cobalt acid lithium, this positive electrode is calcined or after organic solvent soaks, is peeled off the aluminium flake on the positive electrode, obtain containing the black solid material of cobalt acid lithium, the black solid material that will contain cobalt acid lithium places under the acid condition uses H
