Abstract
The utility model provides a formation cup for lithium cell formation, relates to tooling clamps in the battery industry, in particular to an electrolyte overflow cup for lithium cell formation, and mainly solves the problems of high manufacturing cost, large electricity consumption, and high construction cost and running cost caused by a formation workshop which is required to be built during the formation (pre-charging) process of a high-capacity lithium cell. The formation cup for lithium cell formation adopts the structure that the cup body of the formation cup is a hollow cylinder body; one end of the cylinder body is in threaded connection with a cup lid; the other end of the cylinder body is in threaded connection with a cup bottom; and through holes are formed in the cup lid and the cup bottom in the axial direction of the cup body. During use, the cup bottom is connected with a cell liquid injection hole, the cup lid is connected with a 1/4 ball valve, vacuum processing is conducted on the cell through a vacuum pump, and electrolyte overflows from the cell enters the formation cup so as not to contact with air, so that the quality of the cell is guaranteed; and as the building of the formation workshop is eliminated, the cost is reduced greatly.
Description
Technical field
The utility model relates to the frock clamp that a kind of battery industry is used, and specifically relates to the electrolyte overflow cup that formation of Li-ion batteries is used.
Background technology
Present high-capacity lithium battery is in changing into (precharge) process, battery pole piece, electrolyte are when charging for the first time, and inside battery can produce overflowing of gas and electrolyte, and the electrolyte that overflows also need be added again, the hydrophily of electrolyte is very strong, and lithium battery interior is the most water funk minute.Present battery producer makes drying shed to formation workshop.So in process of production, the first waste that can cause electrolyte; Second builds the drying shed unit that need to dehumidify, and the 3rd, need a large amount of electric power during the work of dehumidifying unit.The cost that existing drying shed is every square metre needs about 1400 yuan.A formation workshop area 50m
2, then cost is 70,000 yuan.50m
2Drying shed need the dehumidifier of 80KW, the price of dehumidifier is at 300,000 yuan ~ 800,000 yuan.The dehumidifying unit needed start shooting in 24 hours, the power consumption by 80%, and average power consumption every day 1536 degree, it is electric that the expense in 1 year was calculated as 46.08 ten thousand degree by 300 days, about 500,000 yuan of the expenses in 1 year.Therefore, present formation workshop needs very high construction cost and operating cost.
Summary of the invention
The purpose of this utility model is for above-mentioned deficiency, and saving production cost of proposing guarantees that the formation of Li-ion batteries of product quality is with changing into cup.
Technical solution of the present utility model is: formation of Li-ion batteries is with changing into the cylindrical shell that glass cup is a hollow, one end and the bowl cover of cylindrical shell are threaded connection, the other end of cylindrical shell is threaded connection at an end with cup, bowl cover and cup at the end along the through hole that is axially arranged with that changes into glass cup.
Bowl cover described in the technical solution of the present utility model and the cup end, are threaded in the two ends that change into glass cup by " O " RunddichtringO respectively.
The utility model will be connected with the liquid injection hole of battery at the bottom of the cup in use, bowl cover is connected with 1/4 o'clock ball valve, with vacuum pump battery is carried out vacuum treatment, because the electrolyte that overflows from battery enters into airtight changing in the cup, not with contact with air, therefore avoided airborne moisture to enter into and changed in cup and the battery, guaranteed the quality of battery, the electrolyte that lacks in the battery can reflux by changing into cup, changes into also recyclable recycling of the electrolyte that stores in the cup; In the battery formation process, use and change into cup, need not build formation workshop, and 500 of the about need of order of classes or grades at school change into cup, each changes into cup by 100 yuan, then need 50,000 yuan, one about 200 ~ 250 yuan in vacuum pump, an order of classes or grades at school needs 100 approximately, and it is also reusable to change into cup, has therefore saved widely production cost.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, change into the cylindrical shell that glass cup 3 is a hollow, adopt the PP material to make, be provided with internal thread at the upper and lower opening end that changes into glass cup 3, an openend that changes into glass cup 3 is threaded with bowl cover 1, is lined with " O " RunddichtringO 2 between glass cup 3 and the bowl cover 1 changing into; Another openend that changes into glass cup 3 was threaded with the cup end 5, cup 3 and cup are lined with " O " RunddichtringO 4 at the end 5, bowl cover 1 and cup at the end 5 along the through hole that is axially arranged with changes into glass cup 3 and link that changes into glass cup 3, bowl cover 1 can adopt the PP material to make, the cup end 5, can adopt 304 above stainless steel materials to make, and " O " RunddichtringO 2,4 can adopt the butyl rubber material to make; Before to firm produced formation of Li-ion batteries, the cup end 5 that changes into cup, be connected with the liquid injection hole of battery by " O " RunddichtringO, and the bowl cover 1 that will change into cup is connected with 1/4 o'clock ball valve, with vacuum pump to battery execution vacuum treatment after, can change into processing to battery; At this moment, inside battery is in negative pressure state, and along with changing into of lithium battery, lithium battery interior can produce gas, has bubble and electrolyte to overflow; Vacuum state before slowly becomes normal pressure even malleation, overflows if any electrolyte during this, can directly enter into to change in the cup, and not can with contact with air, thereby can not allow airborne moisture enter into to change in the cup, guaranteed the quality of battery; The electrolyte that overflows along with emerging of gas, after bubble was emerged, electrolyte can reflux additional, and unnecessary electrolyte still is stored in and changes in the cup, after formation process is finished, unnecessary electrolyte is focused on since not with contact with air, recycling.
