The drying device for the lithium battery cell comprises an oven for roasting the lithium ion battery cell. The lithium ion battery cell is placed inside the oven, a drying agent for drying the lithium ion battery cell is placed inside the oven. By means of the technical scheme, the drying agent can effectively absorb evaporated moisture of the lithium ion battery cell in the oven, steam inside the oven can be reduced continuously, the roasting time is effectively reduced, and the moisture content of the cell is reduced.
Description
Technical field
The utility model belongs to lithium ion battery manufacturing equipment field, relates in particular to a kind of lithium ion battery cell drying equipment.
Background technology
At present in the lithium ion battery industry, producer's positive pole more than 90% all is to adopt non-aqueous technology, most of producer negative pole also is to adopt non-aqueous technology, this carries out strictness control with regard to requiring lithium ion battery manufacturing firm to the moisture of positive and negative pole material, general water content all be require ppm(1,000,000/) level.Yet lithium ion battery cell all contacts with air in each operations such as batch mixing, film-making, assembling unavoidably, causes moisture to exceed technological requirement.Meet technological requirement in order to ensure the lithium ion battery cell water content, lithium ion battery manufacturer all can toast electric core before fluid injection, to reduce the water content of electric core.
The general employing of prior art is put into baking box with lithium-ion electric core and is toasted, though this method can reduce the water content of electric core, stoving time is longer, and effect remains further to be improved.
The utility model content
The purpose of this utility model is to provide a kind of lithium ion battery cell roasting plant, and it is longer to be intended to solve existing roasting plant stoving time, the problem of poor effect.
The utility model is to realize like this, a kind of lithium ion battery cell drying equipment, comprise that one is used for the baking box of baking lithium ion battery cell, described lithium ion battery cell is positioned within the baking box, is provided with the drier for dry lithium ion battery cell in the described baking box.
After adopting above technical scheme, described drier can effectively absorb the moisture that lithium ion battery cell evaporates in the baking box, makes the steam continuous decrease in the baking box, effectively reduces stoving time, has reduced the water content of electric core.
Wherein, described drier is molecular sieve desiccant.
Wherein, described drier is positioned over the top of lithium ion battery cell.
Wherein, it is characterized in that: comprise that also one is used for holding the container of drier.
Wherein, described container bottom is provided with a gauze, and described drier is contained on the gauze.
Wherein, described baking box is the vacuum-pumping baking box.
Description of drawings
Fig. 1 is the schematic diagram of the lithium ion battery cell drying equipment that provides of the utility model embodiment.
Fig. 2 is the schematic perspective view that is used for holding desiccant container that the utility model embodiment provides.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
See also Fig. 1, Fig. 2, the utility model provides a kind of lithium ion battery cell drying equipment, comprises a baking box 1, and described baking box 1 is used for baking lithium ion battery cell 2, reduces its water content, makes it meet technological requirement.Described lithium ion battery cell 2 is positioned within the baking box 1, is provided with the drier 4 for dry lithium ion battery cell 2 in the described baking box 1.
After adopting above technical scheme, described drier 4 can effectively absorb the moisture that lithium ion battery cell 2 evaporates in the baking box 1, makes the steam continuous decrease in the baking box 1, effectively reduces stoving time, has reduced the water content of electric core.It needs to be noted that this lithium ion battery cell drying equipment is not limited to dry cell electricity core, but other products such as dry cell pole piece also.
See also Fig. 1, Fig. 2, described drier 4 is molecular sieve desiccant, and in the present embodiment, the fundamental diagram of described molecular sieve desiccant is:
Described molecular sieve desiccant is prior art, in this manual it is not elaborated.Because molecular sieve desiccant is that physics suction and soaking effect are remarkable, shortens the production time thereby can not only significantly shorten drying time, and the reduction electricity core water content of energy vast scale, guarantee that the battery water content meets technological requirement.
In addition, it is little that described molecular sieve desiccant has a particle, take baking box volume little, can do the characteristics that regeneration cycle is used after the use, convenient production not only, and significantly reduced drying cost.At last, described son sieve drier not can with material generation chemical reaction in the electric core 2, the side effect of having avoided drier in the process of suction, to produce.
See also Fig. 1, Fig. 2, described drier 4 is positioned over the top of lithium ion battery cell 2.After adopting above technical scheme, described drier 4 can effectively absorb the steam that upwards evaporates from electric core 2, improved drying efficiency greatly.
See also Fig. 1, Fig. 2, described lithium ion battery cell drying equipment comprises that also one is used for holding the container 3 of drier, and in the present embodiment, described container 3 is circular, and its below is provided with a gauze 31, and described drier 4 is tiled on the gauze 31.After adopting above technical scheme, described drier 4 above and belows can absorb the moisture in the baking box 1 simultaneously, and water-taking efficiency doubles.It is worthy of note that the user also can arrange two-layer in container 3 or multilayer gauze 31 as required, and drier 4 is tiled on the gauze 31, drying effect is better.
See also Fig. 1, Fig. 2, described baking box 1 is the vacuum-pumping baking box.During dry electric core 2, with baking box 1 state that is evacuated, regulate the temperature to 80 degree centigrade of baking box 1, electric core 2 was positioned in the baking box baking 2 days.The gained data are as follows:
Table 1: dry preceding 3 electric core water content
Table 2: 2 days 5 electric core water content of conventional baking process
Table 3: 5 electric core water content behind the adding molecular sieve desiccant
From above form as can be known, adopt dry electric core 2 drying effects of technical scheme that the utility model provides very obvious, can effectively reduce electric core water content and reduction drying time.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
