Abstract
The utility model belongs to the technical field of battery test, especially, relate to a structure of detectable electricity core weeping, including electric core, adhesive linkage and detection layer, detection layer passes through the adhesive linkage bond in electricity core surface. When battery leakage, as long as the electrolyte infiltrate adhesive linkage of battery and detection layer contact, make electrolyte take place reaction (composition be among methyl red, bromocresol green and the thymol blue at least a) with the inside composition of detection layer fast, make detection layer discolour to remind user and user to discover the weeping condition as early as possible, reach the purpose of getting rid of the potential safety hazard.
Description
Technical field
The utility model belongs to battery detecting technical field, particularly relates to a kind of structure detecting battery core leakage.
Background technology
The plurality of advantages such as the one of eco-friendly power source, to have voltage high due to it for lithium ion battery, and charge and discharge circulation life is long, and the little and self-discharge rate of environmental pollution is low, have been widely used in each electronic product, and have obtained the accreditation in market.If lithium battery seals during fabrication there is flaw, or improper use, do not use for a long time the risk of leakage, again because the electrolyte of lithium ion battery is generally transparent or faint yellow, tasteless or have faint odor, people not easily discover, except affect battery function and except the life-span, electrolyte or the one of lithium battery are with corrosivity and flammable organic solvent, the electrolyte leaked out can corrode terminal equipment, reaches certain condition, also can on fire or blast.
Utility model content
The purpose of this utility model is: for the deficiencies in the prior art, and a kind of structure detecting battery core leakage is provided, when battery leakage, the electrolyte infiltrate adhesive linkage of battery and contacting with detection layers, just can react with electrolyte rapidly, allow detection layers variable color, make user and user find leakage situation as early as possible, to get rid of potential safety hazard.
For achieving the above object, the utility model adopts following technical scheme:
Detect a structure for battery core leakage, comprise battery core, adhesive linkage and detection layers, described detection layers is adhered to described battery core surface by described adhesive linkage.
Improve as the one detecting the structure of battery core leakage described in the utility model, the thickness of described detection layers is 0.03 ~ 0.08mm.
Improve as the one detecting the structure of battery core leakage described in the utility model, the thickness of described detection layers is 0.05mm.
Improve as the one detecting the structure of battery core leakage described in the utility model, also comprise back stamp brush layer, described back stamp brush layer is coated on the surface of described detection layers.
Improve as the one detecting the structure of battery core leakage described in the utility model, also comprise transparent plastic book film, described transparent plastic book membrane cover is located on described back stamp brush layer.
The beneficial effects of the utility model are: the utility model comprises battery core, adhesive linkage and detection layers, and described detection layers is adhered to described battery core surface by described adhesive linkage.When battery leakage, as long as the electrolyte infiltrate adhesive linkage of battery contacts with detection layers, electrolyte is made to react (composition is at least one in methyl red, bromocresol green and thymol blue) rapidly with the composition of detection layers inside, impel detection layers variable color, to remind user and user to find leakage situation as early as possible, reach the object getting rid of potential safety hazard.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with embodiment and Figure of description, the utility model is described in further detail, but execution mode of the present utility model is not limited thereto.
As shown in Figure 1, a kind of structure detecting battery core leakage, comprise battery core 1, adhesive linkage 2 and detection layers 3, detection layers 3 is adhered to battery core 1 surface by adhesive linkage 2, detection layers 3 can according to the pH value of electrolyte, select methyl red, the indicator of at least one in bromocresol green and thymol blue is as main component, with coating technique even spread or be immersed in above detection layers 3, be used for detecting battery core whether leakage, if battery core has, and leakage situation occurs, electrolyte infiltrate adhesive linkage 2, when contacting with detection layers 3, namely variable color can be produced, the effect playing warning (is equivalent to PH test paper, detect the acid-base value of electrolyte, acid-base value according to electrolyte carrys out variable color).Usually, the thickness of detection layers 3 is 0.03 ~ 0.08mm, and preferably, the thickness of detection layers 3 is 0.05mm, and now detection layers 3 and electrolyte react and is in optimum state.
The utility model also comprises back stamp brush layer 4 and transparent plastic book film 5; back stamp brush layer 4 is coated on the surface of detection layers 3; for playing mark action; transparent plastic book film 5 is covered on back stamp brush layer 4; both played the effect of protection back stamp brush layer 4, the information of the printing of back stamp brush layer 4 can not have been blocked again.
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also change above-mentioned execution mode and revise.Therefore, the utility model is not limited to above-mentioned embodiment, and any apparent improvement of every those skilled in the art done by basis of the present utility model, replacement or modification all belong to protection range of the present utility model.In addition, although employ some specific terms in this specification, these terms just for convenience of description, do not form any restriction to the utility model.
Claims (3)
1. can detect a structure for battery core leakage, it is characterized in that: comprise battery core, adhesive linkage, detection layers, back stamp brush layer and transparent plastic book film, described detection layers is adhered to described battery core surface by described adhesive linkage; Described back stamp brush layer is coated on the surface of described detection layers, and described transparent plastic book membrane cover is located on described back stamp brush layer.
