Abstract
The invention discloses a battery which comprises a housing, a battery cell arranged in the housing, an insulating patch for closing the top end of the housing, an electrode bar partially protruding out of the top end of the housing and a metal cap of the electrode bar, wherein the metal cap covers the outside of the housing and is provided with an exhaust hole, and the insulation strip comprises a metal matrix and an insulation coating coated outside the metal matrix. The invention also discloses the insulating patch for the battery.
Description
[technical field]
The present invention relates to a kind of battery, particularly relate to a kind of battery with insulation dough sheet.
[background technology]
The security performance of battery is extremely important, present battery such as Ni-MH battery, common dry cell etc., the material of the insulation dough sheet of its inside is PVC (Polyvinylchloride, polyvinyl chloride) or PP high molecular polymers such as (Polypropylene, polypropylene).When battery is under the harsh condition, as short circuit, baked wheaten cake etc., insulating surfaces sector-meeting fusing, electric core can produce a large amount of gas owing to be heated simultaneously, comprises hydrogen and oxygen.The insulating surfaces sector-meeting of fusing is discharged and is flow in the steam vent of battery along with gas.When the insulation dough sheet of fusing arrives steam vent, be subjected to the cooling of cool ambient air, the insulating surfaces sector-meeting of fusing is cooled to solid immediately and steam vent is stopped up.The gas that so electric in-core portion produces just can't successfully be discharged battery, thereby causes battery explosion.
[summary of the invention]
The object of the present invention is to provide a kind of battery and employed insulation dough sheet thereof, it avoids the steam vent of battery blocked.
For achieving the above object, the present invention adopts following technical scheme: a kind of battery, comprise shell, be installed in electric core in the described shell, the electrode bar on the insulation dough sheet on the top of the described shell of sealing, top that part stretches out described shell and outside described shell, be covered with the metal cap of described electrode bar, described metal cap offers steam vent, and described insulation dough sheet comprises metallic matrix and is coated with is located at the outer insulating coating of described metallic matrix.
In a preferred embodiment, described insulating coating coats described metallic matrix.
In a preferred embodiment, the thickness of described insulating coating is less than the thickness of described metallic matrix.
In a preferred embodiment, described insulating coating adopts insulating plastics material.
In a preferred embodiment, described steam vent is located at the sidewall that described metal cap exceeds described shell.
For achieving the above object, the present invention also adopts following technical scheme: the insulation dough sheet that a kind of battery is used comprises metallic matrix and is coated with and is located at the outer insulating coating of described metallic matrix.
In a preferred embodiment, described insulating coating coats described metallic matrix.
In a preferred embodiment, the thickness of described insulating coating is less than the thickness of described metallic matrix.
In a preferred embodiment, described insulating coating adopts insulating plastics material.
With respect to prior art, the insulation dough sheet of battery of the present invention is coated with insulating coating outside metallic matrix, and metallic matrix is difficult for fusing, and the amount of insulating coating fusing volatilization is less, can not stop up the steam vent of battery.
[description of drawings]
Fig. 1 is the schematic diagram of the battery of an embodiment;
The schematic diagram of the insulation dough sheet that Fig. 2 uses for battery shown in Figure 1.
[embodiment]
Please refer to Fig. 1 and Fig. 2, the battery 100 of present embodiment comprises shell 1, be installed in electric core 2 in the shell 1, the electrode bar 4 on the insulation dough sheet 3 on the top 11 of closure 1, top 11 that part stretches out shell 1 and be covered with the metal cap 5 of electrode bar 4 outside shell 1.Metal cap 5 offers steam vent 51, and steam vent 51 is located at the sidewall that metal cap 5 exceeds shell 1.When electric core 2 was heated generation gas, gas can flow to outside the battery 100 by steam vent 51, prevented that gas savings in shell 1 from too much causing battery 100 blasts.
Present embodiment is a kind of Ni-MH battery, certainly the also battery of other kinds.Ni-MH battery has advantages such as environmental protection, life-span are good, technical maturity.
The above embodiment has only expressed several execution mode of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection range of patent of the present invention should be as the criterion with claims.
Claims (9)
