Abstract
The invention discloses a novel lithium ion battery cover plate, which comprises two plastic layers and a stainless steel layer sandwiched between the two plastic layers. The two plastic layers are compounded on the stainless steel layer by injection molding. By adopting the plastic-stainless steel-plastic three-layer compound superposed structure, the volume (compared with a pure plastic shell) of the battery shell can be reduced, the volumetric specific energy of the battery is improved, and the advantages of simplicity and convenience in the processing and liquid-filling methods of the plastic cover plate can be fully exerted at the same time; and the insulating performance and the work efficiency of the shell can be improved.
Description
(1) technical field
The present invention relates to a kind of lithium ion battery cover board.
(2) background technology
General pure plastic housing cover plate or the clean steel housing-plate of adopting of existing lithium ion battery cover board.The shortcoming that pure plastic housing cover plate exists is: volume is bigger, therefore causes the volume of battery specific energy less.The shortcoming that the clean steel housing-plate exists is: relatively poor, the faradic intensity of its insulation property is bigger.
(3) summary of the invention
In order to overcome the deficiency of existing lithium ion battery cover board, the invention provides and a kind ofly reduce battery cover board volume, good insulation preformance, significantly reduce the new type lithium ion battery cover plate of faradic intensity.
The technical scheme that the present invention solves its technical problem is: a kind of new type lithium ion battery cover plate is characterized in that: comprise the two layers of plastic layer and be sandwiched in the middle stainless steel layer of two layers of plastic layer.
Further, described two layers of plastic layer is compound on the described stainless steel layer by injection moulding.
Further, the material of described plastic layer is PP or PE or FRPP.
Beneficial effect of the present invention is: by adopting this plastics-stainless steel-three layers of complex superposition structure of plastics, can reduce battery case volume (comparing) on the one hand with pure plastic housing, thereby improved the battery volumetric specific energy, can give full play to plastic cover plate processing and the easy advantage of electrolyte filling method simultaneously again; Can improve casing insulation performance and operating efficiency (comparing) on the other hand with the clean steel shell.With the 80Ah lithium ion battery is example, compares with pure plastic housing, can reduce by about 24% volume, thereby the volume of battery specific energy can be improved 31.6%; Compare with the clean steel shell, can stop battery drain and significantly reduce faradic intensity, thereby guarantee the safe handling of battery, on the other hand, by Mold Making, consistent production in batches, thus significantly increase work efficiency.
(4) description of drawings
Fig. 1 is a structural representation of the present invention.
(5) embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
With reference to Fig. 1, a kind of new type lithium ion battery cover plate comprises two layers of plastic layer 1 and the stainless steel layer 2 that is sandwiched in two layers of plastic layer 1 centre, and described two layers of plastic layer 1 is compound on the described stainless steel layer 2 by injection moulding.The material of described plastic layer 1 can be PP (polypropylene), also can be PE (polyethylene) or FRPP (fiber glass reinforced polypropylene) etc.
The present invention is by adopting this plastics-stainless steel-three layers of complex superposition structure of plastics, can reduce battery case volume (comparing) on the one hand with pure plastic housing, thereby improved the battery volumetric specific energy, can give full play to plastic cover plate processing and the easy advantage of electrolyte filling method simultaneously again; Can improve casing insulation performance and operating efficiency (comparing) on the other hand with the clean steel shell.With the 80Ah lithium ion battery is example, compares with pure plastic housing, can reduce by about 24% volume, thereby the volume of battery specific energy can be improved 31.6%; Compare with the clean steel shell, can stop battery drain and significantly reduce faradic intensity, thereby guarantee the safe handling of battery, on the other hand, by Mold Making, consistent production in batches, thus significantly increase work efficiency.
