Description
Technical field
The utility model relates to a kind of ion battery.
Background technology
The battery core of the lithium-ion battery with aluminium plastic film of ordinary construction, in manufacturing process, adopts adhesive tape or high temperature gummed tape to be fixed, then carries out aluminum plastic film encapsulation to it, and adopts and one-sidedly carry out injecting electrolytic solution and drawing liquid.The aluminum plastic film battery made with aforesaid way, because the colloid of the dissolving in electrolyte to adhesive tape has dissolution; One-sided drawing liquid can to battery battery core unbalance stress.Therefore the damage ratio that the electrolyte in battery is subject to is comparatively large, battery battery core stressed also uneven the closer to drawing liquid fluid injection side, and its pressure be subject to is also larger, and the uptake of electrolyte is also less, so the chemical property of the normal temperature of battery and high temperature is also just poor.
Utility model content
The purpose of this utility model is to provide the aluminum plastic film lithium-ion power battery structure of a kind of high life.
The purpose of this utility model is achieved in that
A kind of lithium-ion-power cell, it comprises battery core, PP plate, PP plate fixed border and lug fixed border, it is characterized in that, cover PP plate respectively at the upper and lower faces of battery core, the described PP plate of upper and lower faces adopts PP plate fixed border to be fixed, and the both sides of the lug of battery core adopt lug fixed border to be fixed.
Wherein, PP plate fixed border is C type fixed border, and C type fixed border leaves circular hole, and lug fixed border is that [type fixed border [type fixed border leaves square opening.
Wherein, battery core is stacked or takeup type structure.
Wherein, battery core be monolateral go out lug or bilateral discharging lug.
Wherein, the material of PP plate fixed border and lug fixed border is PP, PVC, UPVC, aluminium, copper or polymer matrix composites.
Wherein, battery core is square.
Wherein, the described battery core aluminum plastic film after adopting PP plate and described frame to fix encapsulates.
Wherein, barrier film is porous polypropylene film.
Aluminum plastic film lithium-ion-power cell of the present utility model, electrolyte uptake is large, and decrease the pollution of electrolyte, internal resistance is little, good cycle, is suitable for the electrokinetic cell doing various function.

Embodiment
Embodiment 1
The making of square overlapped way battery:
Get 8 positive plates (positive electrode material is coated on the positive and negative surface of aluminium foil) and 9 negative plates (negative material is coated on the positive and negative surface of Copper Foil), (barrier film used is porous polypropylene film 9 negative plates to be inserted into respectively the barrier film of 9 doublings, width is 110mm, thickness is 40um) in the middle of, the end of barrier film grows more than 10mm than the end of negative plate, and the material district part of negative plate is positioned at the middle of barrier film.During lamination, first put a PP plate at the bottom, then a negative plate wrapped with barrier film is being put, a positive plate is put above last, the aluminium foil side of positive plate and the Copper Foil side of negative plate will oppositely be placed and the material district part of negative plate will cover the material district part of positive plate completely, then on positive pole, stack a negative plate wrapped with barrier film, this negative plate will align with the negative plate of bottom, and then on negative plate, stacking a positive plate, this positive plate will align with positive plate below.Repeat above-mentioned work, finally above negative pole, place a PP plate, obtain battery core 1.The both sides up and down of C type frame 3 pairs of battery cores are adopted to be fixed, as shown in Figure 2.C type frame leaves circular hole (as shown in Figure 6), be beneficial to the infiltration of electrolyte after fluid injection.On the positive pole aluminium foil of battery core, weld an anode ear 5 with blob of viscose with ultrasonic bonder, the negative copper foil of battery core welds a negative electrode lug 6 with blob of viscose, and solder joint will be uniformly distributed.Then adopt that [type frame 4 pairs of cell polar ear both sides are fixed, and lug and the exposed aluminium foil Copper Foil of both positive and negative polarity are through [the square opening (shown in Fig. 8 square hole) of type frame.Finally the battery core aluminum plastic film having welded lug is encapsulated, inject electrolyte, change into the aluminum plastic film lithium-ion-power cell that rear obtained capacity is 5Ah.Owing to having the C type frame of fixation in battery core and [type frame, battery core can inject more electrolyte, and simultaneously battery core keeps certain hardness.
Embodiment 2
The pole piece manufacturing process of battery is with embodiment 1.Get 15 positive plates and 16 negative plates, the assembling of battery is with embodiment 1.Finally obtained capacity is the aluminum plastic film lithium-ion-power cell of 9.5Ah.
