Abstract
The utility model discloses a backflow device used for formatting a flexible-packaging lithium ion battery. The backflow device mainly consists of a connecting pipe, a liquid storage bottle, an automatic control valve, a backflow pipe and a program control part, wherein the two ends of the connecting pipe are provided with interfaces used for connecting a vacuum pump and an inert gas storage; a side interface is connected with an upper port of the liquid storage bottle; the automatic control valve is arranged at the lower port of the liquid storage bottle; and the backflow pipe is arranged under the automatic control valve. Four-ten liquid storage pipes are connected on the connecting pipe in parallel; and the automatic control valve is internally provided with an internal contact. The backflow device is used for formatting the flexible-packaging lithium ion battery, can automatically realize the air exhaust in the battery and the back pressure of electrolyte, and can save the material, simplify the technique and lower the production cost; in addition, the air is exhausted thoroughly, the formatting effect of the battery can be improved, and the cycle life of the battery is prolonged.
Description
Technical field
The utility model relates to and a kind ofly is used to make changing into of flexible packing lithium ion battery and uses reflux.
Background technology
Battery changes into exactly by certain and discharges and recharges the process that battery that standard will make activates.Lithium ion battery can produce gas in formation process, gas must in time be removed, and not so can influence the performance of battery.Flexible packing lithium ion battery is a kind of novel package lithium ion battery that grows up on duricrust (box hat, aluminum hull) basis, but owing to be flexible package, so can not adopt the such uncovered mode that changes into of duricrust lithium ion battery.No matter adopt which kind of mode exhaust, prerequisite all is to contact any moisture, because the organic electrolyte of lithium ion battery and water easily react.The chemical synthesizing method of flexible packing lithium ion battery generally is a gasbag-type at present, when promptly packing electric core, except that encasing electric core fully, leave a part of aluminum plastic film and be used to do air bag with aluminum plastic film, the gas that generates in the storage formation process changes into end back excision air bag and encapsulates.The shortcoming of this method is the waste aluminum plastic film, increases the battery production cost, and battery capacity is big more, wastes manyly more, and the gas of Chan Shenging can not be eliminated thoroughly in addition, changes into complex steps.Make improvements the gasbag-type chemical synthesizing method, key is that advanced and applicable formation device will be arranged.
The utility model content
The technical problems to be solved in the utility model is the weak point that overcomes existing gasbag-type chemical synthesizing method, provide a kind of changing into to use reflux, adopt this device that flexible packing lithium ion battery is changed into, can reduce production costs, improve battery formation effect and cycle life.
The technical solution of the utility model is: flexible packing lithium ion battery changes into uses reflux, its improvements are: mainly be made of tube connector, liquid storage bottle, autocontrol valve, return duct and program control part, there is interface at the two ends of described tube connector, side direction has interface, the upper port of described liquid storage bottle is connected with the side direction interface of tube connector, described autocontrol valve is located at the lower port of liquid storage bottle, and described return duct is located at the autocontrol valve below.
Further scheme is: described liquid storage bottle is 4～10, and each liquid storage bottle is connected in parallel on the tube connector; Each liquid storage bottle size is consistent, and its lower port seat is contour, and lower port seat is higher than return duct lower end 20～120cm; Be provided with the interior contact that is connected with program control part in the described autocontrol valve.
During the work of this reflux, two end interfaces of tube connector are connected with the inert gas holder with vacuum pump respectively, and the lower port of return duct is connected with the liquid injection pipe that leaves after the aluminum plastic film of battery is packed.In the charge and discharge process, start vacuum pump the aluminum plastic film inner chamber is vacuumized, gauge pressure vacuum degree is generally 0.05～0.06MPa, closes vacuum pump after discharging and recharging end, utilize inert gas will be evacuated to the interior part electrolyte back pressure of liquid storage bottle, by autocontrol valve control back pressure amount.This device can utilize common vacuum pump and inert gas holder, simultaneously a plurality of batteries is changed into, and to each battery control back pressure amount, gas does not enter inside battery when guaranteeing back pressure respectively, and this device is reusable.Adopt this device that flexible packing lithium ion battery is changed into, can save material (aluminum plastic film does not need to stay air bag), simplify technology, reduce production costs, and vacuumize by setup program and back pressure electrolyte, make the interior air scavenge of battery thorough, improve the battery formation effect, prolong battery cycle life.
Description of drawings
Accompanying drawing is the utility model structural representation.
Embodiment
Further specify the utility model below in conjunction with accompanying drawing.
As figure, the upper port of five liquid storage bottles 3 is connected in parallel on the side direction interface of tube connector 5, two end interfaces 4 of tube connector 5 with 6 respectively in order to be connected vacuum pump and inert gas holder, the autocontrol valve 2 of contact in establishing in the bottom of liquid storage bottle 3 is provided with, the autocontrol valve below connects return duct 1, each liquid storage bottle size is consistent, lower port is contour, lower port seat is higher than return duct lower port 80cm, the valve of described vacuum pump and inert gas holder and autocontrol valve all are connected with program control part with interior contact, by setup program action.
Claims (4)
1. a flexible packing lithium ion battery changes into and uses reflux, it is characterized in that: mainly constitute by tube connector, liquid storage bottle, autocontrol valve, return duct and program control part, there is interface at the two ends of described tube connector, side direction has interface, the upper port of described liquid storage bottle is connected with the side direction interface of tube connector, described autocontrol valve is located at the lower port of liquid storage bottle, and described return duct is located at the autocontrol valve below.
