Abstract
The present invention relates to a kind of pressure release type safe lithium battery, includes lithium battery body, is characterized in：Positive pole ear and negative lug are provided with the conducting port of lithium battery body, and pressure release component is provided with lithium battery body.So, the presence for the pressure release component being made up of air bag, can effectively absorb the flatulence that lithium battery body is likely to occur when in use.Thus, the leakage of gas is prevented, improves the safe coefficient used.Meanwhile simple structure of the present invention, it is worthy to be popularized.
Description
Technical field
The present invention relates to a kind of battery, more particularly to a kind of pressure release type safe lithium battery.
Background technology
Lithium ion battery is a kind of rechargeable battery, and it relies primarily on lithium ion, and movement carrys out work between a positive electrode and a negative electrode.Filling
In discharge process, Li+ comes and goes insertion and deintercalation between two electrodes：During rechargable battery, Li+ is from positive pole deintercalation, by electrolyte
Embedded negative pole, negative pole are in rich lithium state；It is then opposite during electric discharge.It is general to use electricity of the material as electrode for containing elemental lithium
Pond.It is the representative of modern high performance battery.But existing Li ion cells unit lacks necessary security component, once it is electric
Pond expands, and easily causes potential safety hazard.
The content of the invention
The purpose of the present invention is exactly to solve the above-mentioned problems in the prior art, there is provided a kind of safe lithium electricity of pressure release type
Pond.
The purpose of the present invention is achieved through the following technical solutions：A kind of pressure release type safe lithium battery, include lithium battery body,
Wherein：Positive pole ear and negative lug are provided with the conducting port of described lithium battery body, on described lithium battery body
It is provided with pressure release component.Further, above-mentioned a kind of pressure release type safe lithium battery, wherein：Described pressure release component is arranged on
The side of lithium battery body, or described pressure release component are arranged on the side of lithium battery body, or described pressure release component
It is arranged on the bottom of lithium battery body.Further, above-mentioned a kind of pressure release type safe lithium battery, wherein：Described pressure release
Component is air bag.
Further, above-mentioned a kind of pressure release type safe lithium battery, wherein：Described pressure release component is air bag.
Further, above-mentioned a kind of pressure release type safe lithium battery, wherein：Interlayer is provided with described air bag.
Yet further, above-mentioned a kind of pressure release type safe lithium battery, wherein：The body phase mutual conductance of described air bag and battery
It is logical.So, gas can directly or in the case of certain pressure enter air bag from body.
The advantages of technical solution of the present invention, is mainly reflected in：The presence for the pressure release component being made up of air bag, can effectively absorb
The flatulence that lithium battery body is likely to occur when in use.Thus, the leakage of gas is prevented, improves the safe coefficient used.Meanwhile
Simple structure of the present invention, is worthy to be popularized.
The purpose of the present invention, advantage and feature, it will be illustrated and explained by the non-limitative illustration of preferred embodiment below.
These embodiments are only the prominent examples using technical solution of the present invention, all to take equivalent substitution or equivalent transformation and formed
Technical scheme, all fall within the scope of protection of present invention.
Brief description of the drawings
Fig. 1 is the organigram that air bag is arranged on battery body side；
Fig. 2 is the organigram that air bag is arranged on battery body bottom surface.
Embodiment
A kind of pressure release type safe lithium battery as shown in Figure 1 and Figure 2, includes lithium battery body 1, and its unusual part is：
Positive pole ear 2 and negative lug 3 are provided with the conducting port of lithium battery body 1 of the present invention.Meanwhile in lithium battery
Pressure release component is provided with body 1.
From the point of view of a preferable embodiment of the invention, in order to effectively store the gas after bulging occurs in lithium battery body 1, use
Pressure release component be arranged on the side of lithium battery body 1.Certainly, it is contemplated that the placement needs of lithium battery body 1 can be coordinated, adopted
Pressure release component can also be arranged on the bottom of lithium battery body 1.Certainly, pressure release component is arranged on the side of lithium battery body
Can also.Also, need for some special applications, can equally be set simultaneously with bottom in the side of lithium battery body 1
There is pressure release component.
From the point of view of further, it is contemplated that the facility of the manufacturing, while preferably consolidate security, pressure release of the present invention
Component is air bag 4.Meanwhile the mutual conduction of body 1 of air bag 4 and battery.Also, in order to prevent the unexpected damaged of air bag 4 occur
And normal use is influenceed, it is provided with interlayer in the air bag 4 of use.
It is can be seen that by above-mentioned character express using after the present invention, the presence for the pressure release component being made up of air bag can
Effectively absorb the flatulence that lithium battery body is likely to occur when in use.Thus, the leakage of gas is prevented, improves the safe journey used
Degree.Meanwhile simple structure of the present invention, it is worthy to be popularized.
