Abstract
The utility model discloses a kind of novel high-capacity lithium battery casing, comprise outer cover body and the cover plate that is arranged on outer cover body top, cover plate is provided with positive and negative terminals, liquid injection hole and explosion-proof valve, two corresponding large faces of described outer cover body are arranged to the face of cylinder symmetrical and that cave inward, the degree of depth on the described face of cylinder is 1/10～1/20 of outer cover body thickness, and the height of the height on the described face of cylinder and inside battery volume core is suitable.The utility model is arranged to the symmetrical face of cylinder at two large faces of outer cover body, form a cavity that centre is partially thin, both sides are partially thick at battery case inner chamber, fitted the well structure of square coiling battery core of this cavity, thereby make the positive/negative plate of inside battery and barrier film laminating tightr, make the finished product internal resistance of cell more consistent, battery appearance also there will not be the phenomenon such as flatulence, bulge simultaneously, and practical function is good.
Description
Technical field
The utility model relates to a kind of components and parts of lithium battery, the lithium battery casing of the square dynamic lithium battery of especially a kind of large capacity.
Background technology
At present, along with the more and more higher pursuit of the people to healthy living, concern to PM2.5 is more and more deep, electronic public transport is more and more universal in some big and medium-sized cities, the green walking-replacing tool such as electric sedan is also progressively walked close to common people house, and battery is for these Green Travel instruments provide power.Due to the large capacity of quadrate lithium battery and good heat dispersion, it is widely used at the moment in these vehicles.
Current quadrate lithium battery inside is mostly winding type structure, because the intrinsic reasons of equipment such as current coating and coiling cause rolling out the thick intermediate thin in volume core both sides of coming, and current most housing is all rectangular structure, also there is once in a while the square or circular groove that indent is set on the large face of cuboid shell, the volume core practical situation but these all can not be fitted well.
Utility model content
The purpose of this utility model is to provide a kind of novel high-capacity lithium battery casing.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of novel high-capacity lithium battery casing, comprise outer cover body and the cover plate that is arranged on outer cover body top, cover plate is provided with positive and negative terminals, liquid injection hole and explosion-proof valve, two corresponding large faces of described outer cover body are arranged to the face of cylinder symmetrical and that cave inward, the degree of depth on the described face of cylinder is 1/10～1/20 of outer cover body thickness, and the height of the height on the described face of cylinder and inside battery volume core is suitable.
The upper end that described outer cover body is connected with cover plate is rectangle.
The beneficial effects of the utility model: the utility model is arranged to the symmetrical face of cylinder at two large faces of outer cover body, form a cavity that centre is partially thin, both sides are partially thick at battery case inner chamber, fitted the well structure of square coiling battery core of this cavity, thereby make the positive/negative plate of inside battery and barrier film laminating tightr, make the finished product internal resistance of cell more consistent, battery appearance also there will not be the phenomenon such as flatulence, bulge simultaneously, and practical function is good.
Brief description of the drawings
For the ease of it will be appreciated by those skilled in the art that below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model front view.
Embodiment
As depicted in figs. 1 and 2, a kind of novel high-capacity lithium battery casing, comprise outer cover body 4 and the cover plate 2 that is arranged on outer cover body 4 tops, cover plate 2 is provided with positive and negative terminals, liquid injection hole and explosion-proof valve 1, two corresponding large faces of described outer cover body 4 are arranged to the face of cylinder 3 symmetrical and that cave inward, the degree of depth on the described face of cylinder 3 is 1/10～1/20 of outer cover body 4 thickness, and the height of the height on the described face of cylinder 3 and inside battery volume core is suitable.The upper end 5 that outer cover body 4 is connected with cover plate 2 is rectangle.3 bottoms, the face of cylinder extend to outer cover body 4 bottoms, 3 upper ends, the face of cylinder extend to the lower edge of upper end 5, two relative large faces of the utility model outer cover body 4 are taked the face of cylinder, cell thickness is slowly to middle attenuation, the very actual conditions of the thick intermediate thin in edge of laminating volume core, it is partially thin that it forms a centre at battery case inner chamber, the cavity that both sides are partially thick, fitted the well structure of square coiling battery core of this cavity, thereby make the positive/negative plate of inside battery and barrier film laminating tightr, make the finished product internal resistance of cell more consistent, battery appearance also there will not be flatulence simultaneously, the phenomenons such as bulge, practical function is good.
