Abstract
The utility model discloses a safety lithium ion battery, comprising a housing, an electric core held in the housing, and a cover board; and at least two scratches are installed on the outer surface of the housing. Because of the at least two scratches on the outer surface of the housing, the pressure inside the battery is too large to expand the housing when the lithium ion battery is short-circuited or overheated; when the housing is expanded to a certain degree, the battery housing is broken at the scratch place; and the pressure inside the housing can be discharged, thereby having anti-explosion effect.
Description
Technical field
The utility model relates to lithium ion battery field, particularly safety lithium ion cell.
Background technology
Lithium ion battery more and more uses in life, but lithium ion battery is because its intrinsic chemical system, security incident such as can blast in the time of in use.Therefore, need take necessary explosion precaution or device to lithium ion battery.
Summary of the invention
For overcoming above-mentioned technological deficiency, the utility model discloses a kind of safety lithium ion cell.
The technical solution of the utility model is as described below:
The utility model discloses a kind of safety lithium ion cell, comprise housing, be contained in electric core and cover plate in the housing, it is characterized in that: be provided with at least two cuts in described housing outer surface.
Described cut is the even number bar, intersects in twos respectively.
Described cut is two.
Described scratch depth is 0.05-0.1mm.
Lithium ion battery of the present utility model is owing to be provided with at least two cuts on housing outer surface, it is preferably in twos and intersects, be short-circuited or during abnormal conditions such as overheated when lithium ion battery like this, inside battery air pressure is excessive, make the housing bulging, when the housing bulging arrived to a certain degree, the cut infall of battery container broke, venting enclosure interior pressure, thus reach explosion-proof effect.
Description of drawings
Fig. 1 is a lithium ion battery structure schematic diagram of the present utility model.
Specific embodiments
To be elaborated to the utility model by specific embodiment below.
As shown in Figure 1, the utility model discloses a kind of lithium ion battery, comprise housing 22, cover plate 11, and be contained in the interior electric core (not shown) of housing, on described housing 22, be provided with many cuts 33, described cut 33 is preferably the even number bar, and the best is 2, and these 2 cuts 33 intersect.Described scratch depth is chosen as 0.05-0.1mm.Cut is too dark, and the slight bulging of housing also can cause the cut place to be broken, and cut is too shallow, does not reach explosion-proof effect, and security performance is not good.
Lithium ion battery of the present utility model is owing to be provided with at least two cuts on housing outer surface, it is preferably in twos and intersects, be short-circuited or during abnormal conditions such as overheated when lithium ion battery like this, inside battery air pressure is excessive, make the housing bulging, when the housing bulging arrived to a certain degree, the cut infall of battery container broke, venting enclosure interior pressure, thus reach explosion-proof effect.The utility model safe effect is good, and cost is low, and is easy to operate.
In sum; although the utility model is described in detail the utility model structure by specific embodiment; but persons skilled in the art should be understood that; the foregoing description only is the description to preferred embodiment of the present utility model; but not to the restriction of the utility model protection range; persons skilled in the art are in the disclosed technical scope of the utility model, and the variation that can expect easily is all within protection range of the present utility model.
Claims (4)
1. a safety lithium ion cell comprises housing, is contained in electric core and cover plate in the housing, it is characterized in that: be provided with at least two cuts in described housing outer surface.
