Description
Technical field
The present invention relates to a kind of oxygen-impermeable crack methods of scrap lithium ion battery water proof, regenerate for waste and old lithium ion battery
Broken dismantling in the process.
Background technique
By the end of the year 2017, China is accumulative to promote new-energy automobile more than 180 ten thousand, assembles power accumulator about 86.9
GWh, it is retired will to enter scale for new-energy automobile power accumulator after 2018, it is contemplated that accumulative by 2022 will be more than 400,000
Ton.Waste and old lithium ion battery is put into National Hazard waste register, and random heap, which outcasts the soldier, causes extremely seriously big gas and water and soil
Pollution, while also resulting in the significant wastage of valuable resource.It is socio-economic development that waste battery, which is carried out cleaning recycling,
Necessary demand.The key link of waste and old lithium ion battery recycling and reusing is the dismantling of battery, moves back applying waste lithium ionic complexity
It still has a surplus after very high, retired electricity, and organic, the fluorine-containing electrolysis big and inflammable containing the active elemental lithium of chemical property and pollution
Liquid, these substances encounter water and oxygen easily burns, these attributes are that the safe disposal of retired lithium dynamical battery is brought very greatly
Difficulty.Waste and old power battery can generate high temperature during dismantling, and there are toxic exhaust emissions, easily shape during dismantling
At short circuit, battery catches fire is caused to explode, there is biggish environmental pollution and security risk, these problems during Dismantlement
It is extremely inconvenient when battery recycling being caused to recycle or disassemble.Domestic existing old and useless battery disassembling technology and equipment cannot at present
Adapt to power lithium-ion battery dismantling technique requirement, in the prior art, most equipment can only automatic cutting battery electrode
The process that battery core is taken out still is needed manual progress by head, this process has the following disadvantages：1）Entire dismantling process is discontinuous
Production, inefficiency；2）By hand during dismantling, operator is likely to be exposed the liquid of waste cell and sucking pernicious gas, and harm is strong
Health；3）Old and useless battery still has the possibility of explosion, and manual operation has security risk.Therefore lithium ion battery recycling industry compels to be essential
The disassembling technology of automatic high-efficiency rate is wanted, really realizes power battery energy conservation and environmental protection, safe and reliable, efficiently dismantling recycling.
Summary of the invention
The purpose of the present invention is to provide a kind of oxygen-impermeable crack methods of scrap lithium ion battery water proof, realize used Li ion
The safety of battery, standardization dismantling.
The technical scheme is that：
A kind of oxygen-impermeable crack method of scrap lithium ion battery water proof, which is characterized in that the dismantling process of battery is liquid-immersed
Lower completion completely cuts off air and water, includes the following steps：
The lithium ion battery scrapped first is classified by geometric dimension, then in liquid-immersed lower excision terminal, terminal is collected again sharp
With the battery pack for eliminating terminal overturns depoling, and battery case recycles after collecting, and battery core is broken under liquid-immersed by cracker
It is broken.
Further, the liquid for submerging battery is one of dibutyl carbonate, carbonic acid dioctyl ester and diphenyl carbonate
Or it is two or more.
Further, be crushed gained mixing and remove remaining maceration extract through decompression drying after liquid phase separation, electrolyte with
It is recycled after immersion liquid layering.
The beneficial effects of the present invention are：
Method of the invention disassembles lithium ion battery under conditions of exclusion of water and oxygen, and technique is very simple, can be not first
Row excludes the risk of explosion of dismantling process under the premise of carrying out remaining electric discharge treatment to refuse battery, can be realized continuous metaplasia
It produces, high production efficiency is practical, and highly-safe, production capacity is big.
Detailed description of the invention
Fig. 1 is process flow diagram of the invention.
Specific embodiment
Below with reference to embodiment, the invention will be further described.
Embodiment 1：The rectangular or cylindrical lithium ion battery scrapped first is classified by geometric dimension, with two fourth of carbonic acid
Ester is totally submerged as maceration extract, sorted lithium ion battery, and the one end for having electrode tip is cut and terminal recycles, overturning is de-
Battery case is recycled after core, battery core is crushed under submergence, and broken mixing removes remaining leaching through decompression drying after liquid phase separation
Stain liquid, electrolyte recycle after being layered with immersion liquid.
Embodiment 2：The soft-package battery shell scrapped is disassembled, single battery packet is taken out and is soaked in carbonic acid dioctyl ester
It in liquid, cuts battery pack and is crushed, broken mixing removes remaining maceration extract through decompression drying after liquid phase separation, electricity
It is recycled after solution liquid and immersion liquid layering.
Claims (3)
