Abstract
The utility model discloses a vacuum formation device for lithium ion battery formation. The vacuum formation device comprises a box body with an opening and a box cover used for covering the opening of the box body and sealed with the box body, wherein a charge-discharge cable interface is formed in the back surface of the box body; an exhaust pipe is arranged on the box body, and an air inlet pipe is connected to the exhaust pipe. The vacuum formation device disclosed by the utility model can synchronously finish formation and exhaust operations, quickly and completely exhaust gas generated the batteries in a pre-charging process, eliminate the air bubble regions generated by the gases in the battery cells, more effectively form an SEI membrane, effectively improve the volume development and circulation performance of the batteries, effectively eliminate or reduce the pole piece lithium separation condition, prevent the batteries from expanding, eliminate internal pressure, shorten the pre-charging period and play a safe anti-explosion function.
Description
Technical field
The utility model relates to a kind of evacuation apparatus for converting that changes into for lithium ion battery.
Background technology
Changing into exactly of lithium ion battery carried out precharge to battery, the active material in the activated batteries.In the prior art, be under conventional environment, to operate when changing into, electric in-core portion can produce gas, and under conventional environment, electric core gas inside is difficult to be discharged away, influences the formation of SEI film.In addition, along with the increase of battery making capacity, the potential hazard that changes into the stage is also improving.Also do not have at present a kind of evacuation apparatus for converting that changes into for lithium ion battery, vacuum environment both was provided, have explosion prevention function again.
Summary of the invention
A kind of be used to the lithium ion battery formation device that vacuum environment and explosion prevention function are provided in view of also not having at present, the utility model provides a kind of like this evacuation apparatus for converting that changes into for lithium ion battery.
The technical scheme in the invention for solving the technical problem is: a kind of evacuation apparatus for converting that changes into for lithium ion battery, comprise an opening casing, cover the opening of described casing and can with the case lid of box sealing, the back side of described casing offers and discharges and recharges cable port; In order to make this device have better explosion prevention function, the casing material is selected high strength steel for use, and wall thickness〉10mm.
Described casing is provided with exhaust tube, is linked with air inlet pipe on the described exhaust tube.
Further, the end of described exhaust tube is provided with evacuating valve, and the end of described air inlet pipe is provided with air intake valve.
Further, the edge of the edge in described casing front and described case lid is hinged.
Further, described casing and case lid are provided with observation window.
Further, described opening is located at the front of described casing, and described opening is provided with sealing strip.
Further, described opening top is provided with the sealing strip retainer ring, and described sealing strip is located in the described sealing strip retainer ring.
The utility model in use, the battery that need are changed into is packed in the casing, will discharge and recharge cable and penetrate to be connected with battery and discharge and recharge from discharging and recharging cable port, adopts water joint to seal discharging and recharging the cable port place.Connect vacuum extractor to vacuumizing in the casing by exhaust tube then.Change into finish after air inlet pipe open air inlet, open case lid after eliminating vacuum.
The beneficial effects of the utility model are: can finish changing into and bleeding synchronously, discharge the gas that inside battery preliminary filling process produces fast up hill and dale, eliminate the bubble area that electric in-core portion gas produces, more effective formation SEI film effectively improves the capacity of battery and brings into play and cycle performance, and effectively elimination or reduction pole piece are analysed the lithium situation, guarantee not bulging of battery, press in eliminating, shorten pre-charging time, also play the safety anti-explosive effect.
