Description
Technical field
The present invention relates to method for recovering power cells for new energy vehicles.
Background technology
Rely on day by day exhausted petroleum resources for breaking away from, reduce orthodox car exhaust emissions to severe environmental pollution, electric automobile is more and more subject to the attention of countries in the world." country's " 12 " scientific and technological development planning ", will promote the development of New-energy electric vehicle industry during clearly proposing " 12 " energetically.By 2015, electric automobile recoverable amount reached 1,000,000, and output value expection is more than 1,000 hundred million yuan.
The energy of electric automobile is all or part of from electrokinetic cell, and the life-span of electrokinetic cell generally only has 1 to three years, relative to automobile or electric automobile, the replacement frequency of electrokinetic cell is larger, at least needs replacing three to four electrokinetic cells in an electric automobile life cycle.In not far future, when after electric automobile formation scale, need process by having a large amount of electrokinetic cells of scrapping.
At present, the recovery technology of battery is all the recycling for miniature charging batteries such as general battery of mobile phone, digital camera batteries, because the volume of these miniature charging batteries is little, electricity is little, voltage is little, its danger disassembled is smaller, so be all generally adopt staff or Mechanical Crushing, technique is very simple.But Vehicular dynamic battery is because of the use of demand fulfillment automobile, and its volume, voltage and electricity are all very large.And Vehicular dynamic battery is generally by many battery cells or form battery module by tens or several tens of battery monomer and form.With regard to a battery cell, the volume of the miniature charging batteries such as the battery of mobile phone that its volume ratio is general, digital camera battery is large, its voltage and electricity are also high, and thus Vehicular dynamic battery and module thereof and disassembling of monomer all exist very large danger, such as easily on fire or blast.The structure also more complicated of Vehicular dynamic battery, except battery cell, also have the materials such as picture iron plate, copper sheet, electric wire, wiring board, plastics and rubber, its recycling difficulty is very large.And have that volume is large just because of Vehicular dynamic battery, electricity is large, complex structure and disassemble the feature with very large danger, the thus recovery and treatment method of the general miniature charging battery that safety is not high the recycling of inapplicable Vehicular dynamic battery.
But, the electrokinetic cell lost efficacy is not equal to its internal battery or monomer all loses use value, this is because electrokinetic cell requires that internal battery and battery cell have high consistency, any battery monomer hydraulic performance decline all can cause whole electrokinetic cell to lose efficacy.Most of battery cells of inefficacy electrokinetic cell inside still have higher performance (being also called complementary energy), and these battery cells can recycle again, and the complementary energy of electrokinetic cell can be utilized fully effectively can to improve the utilance of resource.And not high for complementary energy, do not continue the battery cell of use value, if only to its simple and easy landfill disposal or simply and easy treat, can cause becoming to them the material that environment is difficult to clear up, secondary pollution and day by day serious destruction are produced to environment.The battery material of electrokinetic cell also has worth in fact, can reclaim these battery materials, recycles, also can improve comprehensive resource utilization rate simultaneously, alleviate environmental pressure and pollution with the material resourcesization realizing dead battery.At present, in the recovery of electrokinetic cell resource and surplus energy utility, also not relevant report.

(4) battery cell is disassembled: discharge to not having the battery cell of use value, then disassemble, when disassembling, the position that shell is disassembled will not damage inside battery both positive and negative polarity pole piece for principle, first from cutter under the positive and negative electrode pole piece of battery cell, cut off and connect positive and negative electrode pole piece and as the Copper Foil of the collector of pole piece or aluminium foil, then break shell along the outer of battery cell, take out positive pole and the cathode pole piece of battery cell; Then adopt magnetic separation, gravity separation, cyclone separation method the material preliminary classification after disassembling, be divided into plastics, metallic copper, metallic aluminium, stainless steel, rubber, anode pole piece, cathode pole piece and diaphragm element, and disassemble the plastics, metallic copper, metallic aluminium, stainless steel, rubber, anode pole piece, cathode pole piece and the diaphragm element that obtain through sorting, fragmentation and the recycling of screening operation;
(5) chemical analysis is carried out to nickel, cobalt, manganese, lithium, iron and titanium elements in the positive and negative electrode pole piece of each batch, obtain the nickel in positive and negative electrode pole piece, cobalt, manganese, lithium, iron and titanium elements content, the combined amount of different batches raw material is determined according to the ratio of nickel, cobalt, manganese, lithium, iron and titanium essential element in target product, adopt the method for hydrometallurgy to extract metallic element, prepare target product;
(6) to the battery cell having use value, by the residual capacitance sorting of battery sorting machine according to battery cell, carry out range by capacitance, and then be applied in product according to actual needs and go.
2. method for recovering power cells for new energy vehicles according to claim 1, is characterized in that, in described step (2) when electrokinetic cell inside is made up of some battery pack, continues to take battery-pack exterior casing and link apart, takes out battery cell.
