The utility model is achieved through the following technical solutions:
The pre-formation device of the non-drying room of a kind of lithium ion battery, it is characterized in that, comprise prismatic battery case and liquid injection hole sealing device with the corresponding opening of battery size, be respectively arranged with the U type groove identical with anode pole and the corresponding position of battery cathode pole on the described battery case, on battery case, be provided with and the corresponding through hole of battery liquid-filling hole size with corresponding position, battery liquid-filling hole with the battery case opening direction; Described liquid injection hole sealing device comprise internal diameter and the corresponding cylindrical seal cover of described through hole, seal shaft, with the corresponding sealing gasket of hole size, setscrew nut and spring, described sealing shroud places on the through hole and with battery case and is connected, on the seal shaft of sealing shroud upper end, be connected with setscrew nut, the portion of external that described seal shaft is positioned at sealing shroud is with spring, described sealing gasket is connected with the lower end of seal shaft by cylindrical adapter sleeve, and the upper end of described seal shaft is connected with draw ring.
The utlity model has following technique effect:
Pre-formation device of the present utility model and lithium-ion-power cell are used, and electrokinetic cell is changed under sealing state in advance, can effectively eliminate the harmful effect of water in air branch to lithium ion battery, improve battery performance.And, can effectively protect lithium ion battery in the environment of non-drying, to change in advance, reduce pre-formation process to requirements for operation circumstances, help reducing the battery manufacturing cost.
Description of drawings
Fig. 1 is the schematic diagram of the pre-formation device of the non-drying room of the utility model lithium ion battery;
Fig. 2 is the schematic diagram of sealing ring;
Fig. 3 is the schematic diagram that pre-formation device of the non-drying room of the utility model lithium ion battery and battery are used.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in detail.
The schematic diagram of the pre-formation device of the non-drying room of the utility model lithium ion battery as shown in Figure 1 and Figure 2, comprise prismatic battery case 1 and liquid injection hole sealing device with the corresponding opening of battery size, be respectively arranged with U type groove 2,3 with anode pole and the corresponding position of battery cathode pole on the described battery case 1, on battery case, be provided with and the corresponding through hole of battery liquid-filling hole size with corresponding position, battery liquid-filling hole.Described liquid injection hole sealing device comprise the corresponding cylindrical seal cover 7 of internal diameter and through hole, seal shaft 8, with corresponding sealing gasket 9 of hole size and spring 6, sealing shroud 7 places on the through hole and with battery case 1 and is connected, on the seal shaft of sealing shroud upper end, be connected with setscrew nut 5, play preventing that seal shaft from falling into the effect in the cylindrical seal cover.The portion of external that seal shaft is positioned at sealing shroud is with spring 6, and sealing gasket 9 is connected with the lower end of seal shaft by cylindrical adapter sleeve 10, and the upper end of seal shaft 8 is connected with draw ring 4.
Fig. 3 is the schematic diagram that pre-formation device of the non-drying room of the utility model lithium ion battery and battery are used.At first with hand with 4 pull-ups of draw ring on the seal shaft, 6 compressions of seal shaft 8 upper springs, move on the seal shaft, in then battery 11 being faced greatly near the liquid injection hole side, anode pole 12, negative pole pole 13 are put into two U type grooves 2,3 on the prismatic battery case, and battery big face is inwardly overlapped with the big face in prismatic battery case bottom.After sealing ring 9 on battery liquid-filling hole and cell sealing axle is corresponding, unclamp draw ring on the seal shaft, spring flicks, and seal shaft moves down under the spring force effect, sealing ring compresses the battery liquid-filling hole under the pressure of spring and seal shaft, realize the sealing to the battery liquid-filling hole.Then battery is shifted out drying room, cooperate with other equipment and carry out changing in advance under the non-drying room environment.Wherein setscrew nut 5 blocks the location with seal shaft on the seal shaft.In the pre-formation process of non-drying room, sealing ring seals the battery liquid-filling hole, and non-drying room air and wherein moisture and the isolation of inside battery electrohydraulic system guarantee that air moisture content can not enter inside battery and influence battery performance, guarantee pre-formation effect.
With electrokinetic cell aluminum hull LP2770102AB size battery is that example is tested.By test, non-drying room changes in advance and changes into cycle performance of battery in advance in cycle performance of battery and the drying room environment and do not have difference.The cycle performance security performance that non-drying room changes into battery in advance all meets the battery testing requirement.
Although the disclosed pre-formation device of the non-drying room of a kind of lithium ion battery that relates to has been carried out special description with reference to embodiment, embodiment described above is illustrative and not restrictive, under the situation that does not break away from spirit and scope of the present utility model, all variations and modification are all within scope of the present utility model.
