Abstract
The utility model discloses apparatus for baking before a kind of lithium ion battery liquid injection, it comprises drying shed (1), vacuum oven (2), transition vacuum oven (3), glove box (4) and transitional storehouse (5), several vacuum oven (2) is provided with in drying shed (1), the rear end of drying shed (1) is communicated with glove box (4) by transition vacuum oven (3), and the rear end of glove box (4) is communicated with transitional storehouse (5).It eliminates by increasing the transition vacuum oven inner drying once before fluid injection water in air part that battery repeats through drying shed or dry channel to absorb, and thoroughly to remove moisture content in battery pole piece, improves the combination property of battery.
Description
Technical field:
The utility model relates to apparatus for baking before a kind of lithium ion battery liquid injection, belongs to lithium ion battery baking technology field.
Background technology:
The features such as lithium ion battery has that nominal voltage is high, specific energy is high, has extended cycle life, memory-less effect, and environmental protection, pollution-free, be therefore widely used in the digital products such as mobile phone, notebook computer, MP3 and all kinds of portable product.
Water content contained in lithium ion battery, on battery impact greatly, when battery pole piece institute water content exceeds standard, can carry out side reaction with electrolyte, cause a devastating effect to battery, such as battery capacity is on the low side, battery generation bulging is exploded, the internal resistance of cell is on the low side, and size is bigger than normal, and cycle performance reduces etc.
Given this, controlling the water content in battery, is be very crucial factor in battery manufacture link.Usual battery producer is controlled by baking drying etc. moisture content at each production link of lithium ion battery, especially before injection electrolyte, carries out drying baking to the battery of not airtight sealing, removes moisture content and be very important.
But battery toasts through vacuumize, need, through being exposed to ambient humidity relative vacuum baking box, after the dry channel that glove box etc. are larger, then to enter glove box fluid injection.But battery, in handling process, again can absorb the moisture content in air, control, have risk to inside battery water content.
Given this, necessaryly provide a kind of battery drying device before entering glove box, eliminate the risk that battery absorbs in transit moisture content again.
Utility model content:
For the problems referred to above, the technical problems to be solved in the utility model is to provide apparatus for baking before a kind of lithium ion battery liquid injection.
Apparatus for baking before the utility model lithium ion battery liquid injection, it comprises drying shed 1, vacuum oven 2, transition vacuum oven 3, glove box 4 and transitional storehouse 5, several vacuum oven 2 is provided with in drying shed 1, the rear end of drying shed 1 is communicated with glove box 4 by transition vacuum oven 3, and the rear end of glove box 4 is communicated with transitional storehouse 5.
As preferably, increase by a joint transition vacuum oven 3 before described glove box 4, carry out supplementing baking;
As preferably, described transition vacuum oven 3 connects into an entirety with glove box 4, directly enters glove box 4, no longer through drying shed or dry channel from transition vacuum oven 3 battery out.
As preferably, described transition vacuum oven 3 is open the door in both sides, is sidelong battery, goes out battery from glove box 4 side from drying shed 1.
As preferably, described transitional storehouse 5 is open the door in both sides, is sidelong battery from glove box 4, to go out battery from glove box 4.
As preferably, described transition vacuum oven 3 is two cavitys.
The beneficial effects of the utility model: it can overcome the drawback of prior art, reasonable in design is novel, by increasing the transition vacuum oven inner drying once before fluid injection, eliminate water in air part that battery repeats through drying shed or dry channel to absorb, thoroughly to remove moisture content in battery pole piece, improve the combination property of battery.
Accompanying drawing illustrates:
For ease of illustrating, the utility model is described in detail by following concrete enforcement and accompanying drawing.
Fig. 1 is the utility model structural representation.
Embodiment:
As shown in Figure 1, this embodiment is by the following technical solutions: it comprises drying shed 1, vacuum oven 2, transition vacuum oven 3, glove box 4 and transitional storehouse 5, several vacuum oven 2 is provided with in drying shed 1, the rear end of drying shed 1 is communicated with glove box 4 by transition vacuum oven 3, and the rear end of glove box 4 is communicated with transitional storehouse 5.
As preferably, increase by a joint transition vacuum oven 3 before described glove box 4, carry out supplementing baking;
As preferably, described transition vacuum oven 3 connects into an entirety with glove box 4, directly enters glove box 4, no longer through drying shed or dry channel from transition vacuum oven 3 battery out.
As preferably, described transition vacuum oven 3 is open the door in both sides, is sidelong battery, goes out battery from glove box 4 side from drying shed 1.
As preferably, described transitional storehouse 5 is open the door in both sides, is sidelong battery from glove box 4, to go out battery from glove box 4.
As preferably, described transition vacuum oven 3 is two cavitys.
The baking method of the battery of this embodiment is: vacuum oven 2 put into by battery, setting vacuum drying process parameter, temperature 80 DEG C, and vacuum degree-85Kpa, changes nitrogen once in every 4 hours, continues dry 24 hours; Taken out by battery in drying shed 1 by battery, drying shed dew point≤30%RH, the control time proceeds to transition vacuum oven 3 in 10min, the technological parameter of setting transition vacuum oven 3, temperature 80 DEG C, vacuum degree-85Kpa, after dry 1 hour, be filled with nitrogen breaking vacuum, after keeping 5-10min, be again again evacuated to≤-85Kpa, then be filled with nitrogen, open glove box 4 side door, battery is taken out.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
