A kind of battery containing soft pack cell of the utility model please refers to the related each figure of Fig. 1 to Fig. 3, in front technical side
It may also is that the soft pack cell ontology 21 is cylindrical on the basis of case, volume is provided in the soft pack cell ontology 21 and is set
Rolling piece in center, first tab 22 and 23 end of the second tab are fixedly connected on the rolling piece, institute
It states the first tab 22 and 23 upper and lower surface of the second tab passes through gel 5 and is fixedly connected on the soft pack cell ontology 21
It lower part and extends radially outwardly from 21 lower part of soft pack cell ontology.In this way, 21 shape of soft pack cell ontology is cylindrical, energy
The shape of 4 shape of bracket is fit into, meanwhile, but also to occupy space small for soft pack cell ontology 21, save space.First tab
It is stretched out on the rolling piece that 22 free end and the free end of the second tab 23 are arranged inside soft pack cell ontology 21, the first tab
22 and second tab 23 can be symmetrical arranged from rolling piece two sides and stretch out, asymmetric can also be arranged.Rolling piece one enclose around
It is located inside soft pack cell ontology 21, is wound by anode pole piece, diaphragm and cathode pole piece and to be formed, diaphragm, which plays, prevents anode
The effect of pole piece and cathode pole piece short circuit.First tab 22 is connected on positive (negative) pole piece and the second tab 23 is connected to negative (just)
On pole piece, specific location can be configured according to the actual situation, be facilitated between soft pack cell ontology 21 and other components
Connection.First tab 22 is bonded gel 5, tab from the upper and lower surfaces of 21 central projection of soft pack cell ontology
5 upper and lower surface of glue has a cementability, and the first tab 22 by gel 5 is bonded in 21 lower part of soft pack cell ontology and from Soft Roll electricity
21 lower part of core ontology extends outwardly；Second tab 23 by gel 5 be bonded in 21 lower part of soft pack cell ontology and from Soft Roll electricity
21 lower part of core ontology extends outwardly.By the way that gel 5 is arranged, prevent the first tab 22 and the second tab 23 and soft pack cell ontology
21 contact, plays insulating effect.Gel 5 extends to outside, can also be only positioned in 21 lower part of soft pack cell ontology
And it does not stretch out.Further preferred technical solution are as follows: the soft pack cell ontology 21 includes upper plastic-aluminum film layer 211, lower aluminum plastic film
Layer 212 and electrolyte connect between the upper plastic-aluminum film layer 211 and lower 212 edge of plastic-aluminum film layer by the way that sealing hot pressing is fixed
It connecing, the electrolyte level is enclosed and is set in the cavity to be formed in the upper plastic-aluminum film layer 211 and the lower plastic-aluminum film layer 212, and described
One tab, 22 end upper and lower surface passes through gel 5 and is adhered to the upper plastic-aluminum film layer 211 and the lower plastic-aluminum film layer 212
On, 23 upper and lower surface of the second tab passes through gel 5 and is adhered to the upper plastic-aluminum film layer 211 and the lower plastic-aluminum film layer
On 212.It sets to form cavity and generally form cylindric, chamber in this way, enclosing between upper plastic-aluminum film layer 211 and lower plastic-aluminum film layer 212
It is filled with electrolyte in vivo.In the cavity by electrolyte setting, it rather than is directly installed in accommodating chamber, reduces 1 He of upper cover
The risk of 3 etching problem of lower cover and the battery drain solution liquid, improves service life.Upper plastic-aluminum film layer 211 is first gone out with mould punching
Then pit shape is connected upper plastic-aluminum film layer 211 with lower 212 edge of plastic-aluminum film layer by hot pressing mode so that the two it
Between connect it is even closer, for accommodating electrolyte.Meanwhile first tab 22 and the second tab 23 from 21 lower part of soft pack cell ontology
It extends radially outwardly, only upper 211 punching press pit of plastic-aluminum film layer need to be simplified installation steps, structure is simple, while also mentioning
The capacitance of high soft pack cell ontology 21.First tab, 22 end upper surface connects by the way that gel 5 is Nian Jie with upper plastic-aluminum film layer 211
It connects；First tab, 22 end lower surface by gel 5 and lower 212 bonding connection of plastic-aluminum film layer so that the first tab 22 with it is upper
Plastic-aluminum film layer 211 and the equal bonding connection of lower plastic-aluminum film layer 212 and insulating effect is played simultaneously.Second tab, 23 end upper surface is logical
Cross gel 5 and upper 211 bonding connection of plastic-aluminum film layer；Second tab, 23 end lower surface passes through gel 5 and lower plastic-aluminum film layer
212 bonding connections, so that the second tab 23 and upper plastic-aluminum film layer 211 and the equal bonding connection of lower plastic-aluminum film layer 212 and playing simultaneously
Insulating effect.Electrolyte is packed into soft pack cell ontology 21, the risk for preventing the battery drain solution liquid can be reached；Such as battery
Diameter is 12mm, and when cell height is 5.4mm, which can reach 50mAh；The cell diameter is 14mm, cell height
When for 5.4mm, which can reach 65mAh；The cell diameter is 10mm, when cell height is 5.4mm, the battery capacity
40mAh can be reached.Technical solution still more preferably are as follows: upper 211 periphery of plastic-aluminum film layer extends radially outward setting
