Description
Technical field
The utility model relates to flexible packaging power lithium ion cell art, particularly a kind of flexible packaging power lithium ion battery folded edges with insulation protection.
Background technology
When adopting flexible package packaged battery, aluminium lamination being produced leak outside after trimming, in order to prevent battery core from corroding or leak outside aluminium lamination and extraneous short circuit, need to use tape sticker on the edge sealing and battery core of battery, thus aluminium lamination trimming place exposed being isolated from the outside.Flexible packing lithium ion battery described in Fig. 1, single flanging is adopted to add the fixing structure of side adhesive tape, flanging is fixed by insulating tape, adopt and the seal edge break of battery core is played 90 ° of formation flangings, then with insulating tape, flanging is clung in battery core, thus the metallic aluminum leaked outside by flanging wraps up, ensure insulation.Fig. 2 is a kind of flexible packing lithium ion battery double-fold structure, comprises flanging I and flanging II, is, single flanging is become double-fold structure with the structure difference in Fig. 1, when ensureing effective seal width, can form less flanging height like this; The battery core flanging of this structure, first by roller set, 180 ° are played to seal edge break and form flanging, then by roller, flanging is turned up 90 °, finally adopt insulating tape to cling in battery core by flanging I and flanging II, thus the metallic aluminum making seal trimming leak outside wraps up, ensure insulation.The shortcoming of above-mentioned two kinds of folded edges all needs to adopt insulating tape to wrap up, and the insulating tape pasted easily tilts, and affect product quality; Above-mentioned two kinds of folded edges are when power battery core PACK assembles simultaneously, do not press battery core flanging and fix monomer battery core, affect security performance and the useful life of battery core by both sides.
Utility model content
The purpose of this utility model is to solve the above-mentioned technical problem existing for existing lithium ion battery folded edges, there is provided a kind of without the need to through encapsulate process, effectively can prevent a kind of flexible packing lithium ion battery folded edges that trimming position metal leaks outside, this folded edges is when power battery core PACK assembles, the flanging pressing battery core by both sides fixes monomer battery core, this folded edges also can increase the effective seal width of battery core side, improve battery core security performance, the useful life of effective prolongation battery core, and greatly improve the qualification rate of automated production efficiency and product.
For solving the problems of the technologies described above, the utility model have employed a kind of flexible packaging power lithium ion battery folded edges, be included in the seal limit of battery core side formation, the first flanging and the second flanging, described first flanging is arranged on seal limit, described second flanging is arranged on the first flanging, described second flanging is connected in 180 ° with seal limit, described first flanging is connected in 180 ° with the second flanging, described seal limit and the first flanging, fit between the first flanging and the second flanging, described first flanging width is less than the second flanging width.
Further, the spacing between the outer side edges of described first flanging and the second flanging connecting portion and battery core is greater than 0.5mm.
The trimming of seal limit is exposed aluminium lamination and is folded in the enclosure space that the first flanging, the second flanging and seal limit formed by the utility model, and adhesive tape need not be adopted can to realize the effect that will expose aluminium lamination and carry out isolating; This eliminate the production stage of taping, not only simplify seaming operation, and save the cost of use of adhesive tape, reduce production cost; And owing to simplifying seaming operation, the automated production efficiency of battery flanging and the qualification rate of product greatly can be improved.
Adopt the utility model when power battery core PACK assembles, the flanging pressing battery core by both sides fixes monomer battery core, and only need not rely on the top of fixing battery core, thus improves the fixing of fixing battery core simultaneously.In addition, when ensureing that battery core width is certain, adding the effective seal width of battery core side by twice flanging, improve battery core security performance, effectively extend the useful life of battery core.
