In lithium ion battery production process, especially for the lithium ion battery with hard shell that energy density is high, because battery filling rate is high, a reservoir quantity can not meet the technological requirement of battery, therefore need to carry out second time fluid injection to battery after Battery formation, to ensure that battery has enough guarantor's liquid measures.
Existing technique uses rubber ring or rubber band to tie up on multiple battery to stand upside down afterwards in the plastic casing that electrolyte is housed, and then vacuumizes and make electrolyte enter inside battery, sealing after wiping cleaning after being taken out by battery.The major defect of this technique is: 1) because battery is put in electrolyte by needs, battery body can adhere to too many electrolyte, and meanwhile, same box electrolyte recycling can not, more than 3 times, cause electrolyte to waste serious; 2) due to electrolyte recycling, cause mutual cross pollution between battery, have extreme influence to the degree of purity of electrolyte; 3) electrolyte sticks on battery body, if clean not in time, very easily produces spot at battery surface, affects battery outward appearance.
Utility model content
Object to be solved in the utility model is for above-mentioned the deficiencies in the prior art, there is provided a kind of reasonable in design, structure simple, flexible and convenient to use, stable work in work, reliable, ensure battery performance, the lithium ion battery with hard shell secondary injection liquid device of the excellent rate of product can be improved.
For achieving the above object, the lithium ion battery with hard shell secondary injection liquid device that the utility model adopts, support is provided with secondary injection sap cavity body, described secondary injection sap cavity body is provided with top cover, the shape of described secondary injection sap cavity body is del, described secondary injection liquid inside cavity is lined with many protruding the first insulation spokes preventing battery short circuit, is provided with battery is separated by many second insulation spokes the slot formed in described secondary injection sap cavity body near del drift angle one end; Described secondary injection sap cavity body is provided with electrolyte injecting hole, vacuum pumping hole, dry gas valve and discharging of waste liquid hole.
The shape of described secondary injection sap cavity body is del and drift angle is right angle.
The first described insulation spoke and the second insulation spoke are all for by material being the insulation spoke that PP, PE, PET or PVC make.
Described secondary injection liquid inside cavities is provided with baffle plate in described electrolyte injecting hole one end, makes electrolyte flow to cavity bottom smoothly, and is unlikely to splash on battery.
The opening part of described secondary injection sap cavity body is provided with sealing strip, during the pressure of top cover described in guarantee and the sealing of described secondary injection sap cavity body.
Described top cover is provided with handle.
Described top cover by hinge and described secondary injection sap cavity body hinged.
Described discharging of waste liquid hole is located at the drift angle of del in described secondary injection sap cavity body.
Described vacuum pumping hole is provided with vacuum valve.
Adopt the lithium ion battery with hard shell secondary injection liquid device of technique scheme, compared with prior art have the following advantages: 1) fluid injection cavity liner insulation spoke, battery short circuit when effectively can avoid secondary fluid injection, reduces the security risk that battery causes because of short circuit; 2) battery all separately can not be contacted between battery by single, decrease the contact battery surface making electrolyte too much due to capillarity in cavity, and the consumption of minimizing electrolyte content decreases the bad order that battery case causes because of spot simultaneously.3) because battery liquid-filling mouth is downward with certain angular slope, can ensure that the area of battery terminal contact electrolyte is minimum, electrolyte consumption can be reduced.
In sum, the utility model be a kind of reasonable in design, structure simple, flexible and convenient to use, stable work in work, reliable, ensure battery performance, the lithium ion battery with hard shell secondary injection liquid device of the excellent rate of product can be improved.
