Problems solved by technology
However, because the outer shell is packaged with aluminum-plastic film, the thickness of the aluminum-plastic film is only 152um or less, and its anti-burr and wear resistance are poor, which seriously restricts the fixing and assembly of the modular single battery after pairing.

Embodiment Construction
[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings: figure 1 As shown, it is the production of the outer frame of the size of the cell glue filling of the present invention: a PET polyester film with a thickness of 0.5 to 2.0 mm is used as the bottom plate 2 of the outer frame, and cheap and easy-to-obtain sponge pads are used around it according to the requirements of the finished product shape and size after glue filling Splicing forms the four walls of the outer frame, and the inner cavity size of the four walls of the outer frame is: three sides on the non-tab side and one single side are wider than the main body of the cell: 5-10mm, and the side of the tab is wider than the main body of the cell: 0-1.0mm. That is to say, when the main body of the battery core is placed inside the outer frame, the gap between the inner wall of the outer frame and the three sides 1 of the non-tab side is kept at: 5-10mm, and i...

The present invention adopts a simple, efficient and low-cost unique method of pouring glue around the edge of the battery shape. The appearance glue filling method of the soft-pack lithium-ion power battery of the present invention is characterized in that: 1. Firstly, an outer frame is made, and an interlayer is arranged in the outer frame; 2. The main body of the battery cell is placed inside the outer frame. Outside the interlayer; 3. At the gap between the outer frame and the battery core, apply a layer of Vaseline or Vaseline in advance to facilitate the peeling between the battery core and the outer frame after the glue is cured. Other degumming agents; 4. Carry out glue filling, that is, pour the uniformly mixed original glue A and cured glue B glue into a disposable paper cup, and then use the paper cup along the gap between the main body of the battery cell and the outer frame 5. Curing the battery cells filled with glue together with the outer frame at room temperature; 6. Peeling the battery cells from the outer frame; 7. Complete the assembly after glue filling. Compared with the prior art, the present invention has the advantages of simplicity, high efficiency, and low cost. After the glue is poured on the edges around it, the single cells are paired to form a module, which is easy to fix and assemble. Through this glue pouring method, thus for The wide application of lithium-ion power batteries in aluminum-plastic film flexible packaging provides a strong guarantee.
Description
Technical field: [0001] The present invention relates to soft-packaged lithium-ion power batteries. Because the shell is made of aluminum-plastic film soft-package, it seriously affects the fixing and assembly of the module monomers formed after pairing. In order to solve this problem, the present invention adopts a simple, efficient, A unique method of low-cost potting around the edges of battery shapes. Background technique: [0002] Energy and the environment are extremely important material foundations for the survival and development of human society. Since the formation of energy systems based on fossil fuels such as oil, coal and natural gas, countries around the world have greatly promoted the prosperity and progress of human society. However, with the painful lessons of various unfortunate disasters encountered by countries in the world today and the continuous improvement of human scientific prediction capabilities, villagers around the world increasingly feel that...
