Abstract
The present invention relates to a regeneration process of a glove box waste molecular sieve for lithium battery liquid injection. The regeneration process comprises: a, treating a failure molecular sieve for 1-12 h at a temperature of 100-280 DEG C so as to remove water in the molecular sieve; b, heating to a temperature of 280-600 DEG C, and treating for 1-28 h so as to remove the water remained in the molecular sieve and the electrolyte organic solvent absorbed in the molecular sieve; and c, re-loading the treated molecular sieve in a glove box so as to be used. The present invention provides the process for recycling the glove box waste molecular sieve for lithium battery liquid injection.
Description
Technical field
The present invention relates to the discarded regenerating molecular sieve technique of a kind of lithium battery fluid injection glove box.
Background technology
That lithium ion battery has is lightweight, volume is little, the life-span is long, advantages of environment protection, is optimal portable power source.In Production Process of Lithium Battery, need strictly to control moisture, often use the moisture in molecular sieve control glove box in fluid injection.When production, molecular sieve absorbs the moisture in glove box, and the moisture that utilizes the thermal regeneration system removal molecular sieve in molecular sieve to absorb when idle has reached the object of regeneration.But molecular sieve is in use for some time due to the organic matter that has adsorbed a large amount of electrolyte and volatilize, and these organic matters use existing regenerative system to be difficult to remove, so the accumulation of organic electrolyte causes molecular sieve pores rate to decline, and then molecular sieve dehumidifying effect is reduced.In the face of the present current way of this problem is exactly the molecular sieve renewing, and the molecular sieve losing efficacy is often just worked as offal treatment, has caused the waste of resource, has increased the cost of enterprise.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of technique that can make the discarded molecular sieve recycling of lithium battery fluid injection glove box.
The technical solution adopted for the present invention to solve the technical problems is: the discarded regenerating molecular sieve technique of glove box for a kind of lithium battery fluid injection, comprise the steps: a, the molecular sieve of inefficacy is processed to 1～12h at the temperature of 100 DEG C～280 DEG C, to remove the moisture in molecular sieve; B and then be warming up to 280 DEG C～600 DEG C and process 1～28h, to remove moisture residual in molecular sieve and to be adsorbed on the electrolyte organic solvent in molecular sieve; C, molecular sieve after treatment is reloaded in glove box and used.
The molecular sieve losing efficacy in step a is processed 3h at the temperature of 170 DEG C.
In step b, be warming up to 340 DEG C and process 6h.
Beneficial effect: the invention solves the defect existing in background technology, carry out high-temperature process twice by discarding molecular sieve, effectively remove moisture and the electrolyte organic solvent in molecular sieve, the dehumidifying effect of discarded molecular sieve is recovered, thereby molecular sieve can be reused, reduce the wasting of resources, reduced production cost.
Detailed description of the invention
The discarded regenerating molecular sieve technique of glove box for a kind of lithium battery fluid injection, comprises the steps: a, the molecular sieve of inefficacy is processed to 1～12h at the temperature of 100 DEG C～280 DEG C, removes the moisture in molecular sieve; B and then be warming up to 280 DEG C～600 DEG C and process 1～28h, removes moisture residual in molecular sieve and is adsorbed on the electrolyte organic solvent in molecular sieve; C, molecular sieve after treatment is reloaded in glove box and is used, can make the moisture in glove box remain on 30ppm(1,000,000/30) below.
Preferred embodiment: the molecular sieve losing efficacy in step a is processed 3h at the temperature of 170 DEG C; In step b, be warming up to 340 DEG C and process 6h.
Should be appreciated that specific embodiment described above, only for explaining the present invention, is not intended to limit the present invention, every by the fluid injection of high-temperature process lithium battery with glove box molecular sieve with the method that can reuse all within protection scope of the present invention.The apparent variation of being extended out by spirit of the present invention or variation are still among protection scope of the present invention.
