Description
Technical field
This utility model belongs to battery structure technical field, is specifically related to battery packages bag insulation protection structure.
Background technology
The packaging bag that traditional Soft Roll encapsulating structure is used is multilayer materials, and wherein one layer is metal level.Based on existing battery core trimming technology, metal level is exposed outside, brings the corrosion of battery core main body or the risk with external world's short circuit.For evading this type of risk, the method used at present has multiple.Described in Fig. 1 is the fixing structure of conventional single flanging additional side glue, battery core main body 1 defines the package wall 2 of battery core after packaging film is packaged, with seal edge break is got up after single flanging 3, the single flanging 3 of 4, adhesive tape finally by one layer of single spreading is fixed at package wall 2, it is ensured that the insulation of trimming and prevent opening of single flanging 3.Fig. 2 is the structure of a kind of double-fold, unlike Fig. 1, single flanging 3 has been folded into double-fold 5, can ensure to be formed less flanging height in the case of wider seal limit.In sliced boundary is wrapped in by double-fold 5, to ensure insulation simultaneously.The shortcoming of two kinds of structures of Fig. 1 and Fig. 2 is that adhesive tape 4 needs to be attached in battery core main body 1, adds the package thickness of battery core main body 1, reduces the energy density of battery.
Battery core edge sealing fixed structure shown in Fig. 3, uses the glue 6 metal to exposing at trimming in side to be dielectrically separated from, and then recycling 7 side glue 6 of adhesive are bonded in package wall 2.But, the automatization of this kind of gluing structure requires that the complexity of equipment is high, and the manufacturing cost of matched side glue 6 is the highest, and the product yield of production is low, and production efficiency is the highest.
Fig. 4 is another kind of double-fold structure, does not use adhesive tape to fix double-fold 5, and be the use of the fixing mode of adhesive 7 unlike Fig. 2.Due to the restriction of technical process, structure shown in Fig. 2 and Fig. 4 cannot apply (single linear trimming refer to insulated and the battery core side of flanging is straight line, without turning and camber line) in the battery core of non-single linear trimming.Owing to double-fold is battery core seal limit have been carried out the turnover of continuous quadratic, if battery core side has turning or arc, it will produce excessive residual stress and cause flanging to open.
