Description
Technical field
The invention belongs to lithium ion battery and manufacture field, be specifically related to one and lithium from battery leftover pieces and is scrapped positive plate
The method carrying out secondary utilization.
Background technology
The main material of based lithium-ion battery positive plate includes for LiFePO 4, other auxiliary material be carbon, glue be poly-inclined tetrafluoro
Ethylene, carrier aluminium foil) etc., in lithium ion battery production process, inevitably produce positive plate leftover pieces, and also meeting
Pole piece is scrapped in generation, generally, due to leftover pieces and scrap the secondary of positive plate and utilize preparation technology, especially separates work
Skill is extremely complex, and the enthusiasm causing battery manufacturer to re-use is greatly reduced, and thereby results in material waste serious, as China is special
Profit CN 104183887 A, it needs through three calcinings, then need through over cleaning, filter, dry, the technique such as ball milling, also
Needing to add lithium carbonate to be modified processing, technique is extremely complex！
Chinese patent CN 103219561 B also discloses a kind of method for recycling anode material, and it is need to forge through 3 times equally
Burn, and also carbonaceous reducing agent need to be added, Silicon stone, Calx carry out mixed smelting, and also need to carry out precipitating, the technique such as filtration.
Above-mentioned technique is the most extremely complex, is unfavorable for the recovery of anode material of lithium battery.
Summary of the invention
For solving the defect that prior art exists, the present invention provides a kind of based lithium-ion battery positive plate secondary utilization method,
It only needs by once calcining, and the feature of varying in weight then making full use of granule carries out gas detached job, the method
The separation and the recovery process that make positive electrode are simplified, and device therefor is with low cost, common apparatus, increases greatly
Add separation efficiency, and add recycling enthusiasm.
For achieving the above object, the present invention is by the following technical solutions: a kind of based lithium-ion battery positive plate secondary utilization side
Method, adopts and is prepared by the following steps:
A is by based lithium-ion battery positive plate leftover pieces or scraps in material input pulverizer, is crushed to nanoscale minitype particle；
The minitype particle that step A prepares is put in high temperature furnace and is burnt 1-5 hour with 200 degree of temperatures above by B, obtains admixture
Lithium, superconduction white carbon black and alumina particles；
C prepares 400 mesh above granule sieves, at the placement air port, bottom of granule sieve hair-dryer upwards, and above granule sieves
Three groups of negative-pressure air fans of longitudinal arrangement, wherein the top negative-pressure air fan connection superconduction white carbon black collection device, bottom negative-pressure air fan is even
Logical aluminum collection device, middle part negative-pressure air fan connection lithium collection device；
D starts hair-dryer and three groups of negative-pressure air fans, and lithium, superconduction white carbon black and alumina particles that step B prepares at the uniform velocity are poured on granule
On sieve；
Lithium collected by LiFePO 4 collection device, superconduction white carbon black collection device and superconduction white carbon black are put into positive plate by E again
Produce, cut through dispensing coating, roll-in, make lithium battery after film-making.
Having the beneficial effects that of the technical program: only need once to calcine, the purpose of calcining is to remove binding agent, viscous
Knot agent, in the case of high-temperature calcination, is decomposed, and then only stays containing lithium granule, superconduction carbon black pellet and alumina particles, and the present invention is closed most
The technology point of key is to take full advantage of the difference of specific gravity (lithium 1.0 to 2.5g/ of lithium granule, superconduction carbon black pellet and alumina particles
cm3;Superconduction carbon is 0.2 below g/cm3, and the proportion of aluminum is more than 4.0g/cm3), under the blowing of hair-dryer, superconduction white carbon black
Being floated to the superiors space, aluminum is floated to orlop space, and lithium then swims in interlayer spaces, then by above granule sieve
Set gradually the absorption superconduction white carbon black collection device of variable grain, lithium collection device, aluminum collection device collect different of recovery
Grain, and then realize detached job, in the case, it is only necessary to the granule after separating according to purposes carries out utilizing, and without
Other operation, the present invention greatly simplify recovery process, adds organic efficiency.
Preferably, the ignition temperature in described step B is 200-500 degree；It is special that the technical program further increases this case
The organic efficiency of profit.
Preferably, described aluminum collection device, superconduction white carbon black collection device, lithium collection device be the pocket with cavity or
Box-shaped body；The technical program, further increases the range of choice of collection device, reduces cost recovery.
Accompanying drawing explanation
It is clear that following drawings and the embodiments are only those skilled in the art fully understands that this case patent is provided
Technical scheme, be not intended that the restriction to this case patent.
Fig. 1 is granule of the present invention sieve, hair-dryer and negative-pressure air fan positional structure schematic diagram.
Detailed description of the invention
A kind of based lithium-ion battery positive plate secondary utilization method, adopts and is prepared by the following steps:
A is by based lithium-ion battery positive plate leftover pieces or scraps in material input pulverizer, is crushed to nanoscale minitype particle；
The minitype particle that step A prepares is put in high temperature furnace and is burnt 2 hours with 400 degree of temperatures above by B, obtains admixture
Lithium, superconduction white carbon black and alumina particles, in this step, calcining heat is the highest, the fewest；
C prepares 400 mesh above granule sieves, as it is shown in figure 1, at the placement air port, bottom of granule sieve 1 hair-dryer 2 upwards, and
Three groups of negative-pressure air fans of the top longitudinal arrangement (3,4,5) of granule sieve 1, wherein the top negative-pressure air fan 3 connects the collection of superconduction white carbon black
