Abstract
The invention relates to a pressure release type safe lithium battery. The lithium battery comprises a lithium battery body, the conduction port of the lithium battery body is provided with an anode tab and a cathode tab, and the lithium battery body is provided with a pressure release assembly. An expanding gas possibly appearing in the use process of the lithium battery body can be effectively absorbed through the pressure release assembly formed by an airbag, so the gas leakage is prevented, and the use safety is improved. The pressure release type safe lithium battery has a simple structure and is worth popularization.
Description
Technical field
The present invention relates to a kind of battery, relate in particular to a kind of pressure release type safe lithium battery.
Background technology
Lithium ion battery is a kind of rechargeable battery, and it mainly relies on lithium ion to move work between positive pole and negative pole.In charge and discharge process, Li+ comes and goes embedding and takes off embedding between two electrodes: during rechargable battery, Li+ takes off embedding from positive pole, embeds negative pole through electrolyte, and negative pole is in rich lithium state; Then opposite during discharge.The general employing contained the material of elemental lithium as the battery of electrode.It is the representative of modern high performance battery.
But existing Li ion cells unit lacks the necessary security assembly, in case expanding appears in battery, causes potential safety hazard easily.
Summary of the invention
Purpose of the present invention is exactly in order to solve the above-mentioned problems in the prior art, and a kind of pressure release type safe lithium battery is provided.
Purpose of the present invention is achieved through the following technical solutions:
A kind of pressure release type safe lithium battery includes the lithium battery body, and wherein: the conducting port of described lithium battery body is provided with positive pole ear and negative lug, and described lithium battery body is provided with the pressure release assembly.
Further, above-mentioned a kind of pressure release type safe lithium battery, wherein: described pressure release assembly is arranged on the side of lithium battery body, or described pressure release assembly is arranged on the side of lithium battery body, or described pressure release assembly 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 assembly is air bag.
Further, above-mentioned a kind of pressure release type safe lithium battery, wherein: described pressure release assembly is air bag.
Further, above-mentioned a kind of pressure release type safe lithium battery, wherein: be provided with interlayer in the described air bag.
Again further, above-mentioned a kind of pressure release type safe lithium battery, wherein: the body mutual conduction of described air bag and battery.Like this, gas can be from body directly or enter air bag under the certain pressure situation.
The advantage of technical solution of the present invention is mainly reflected in: the existence of the pressure release assembly that constitutes by air bag can effectively absorb the flatulence that the lithium battery body may occur in use.Thus, prevent the leakage of gas, improve the safe coefficient of using.Simultaneously, simple structure of the present invention is worthy to be popularized.
Description of drawings
Purpose of the present invention, advantage and characteristics will illustrate by the non-limitative illustration of following preferred embodiment and explain.These embodiment only are the prominent examples of using technical solution of the present invention, and all technical schemes of taking to be equal to replacement or equivalent transformation and forming all drop within the scope of protection of present invention.
Fig. 1 is the organigram that air bag is arranged on the battery body side;
Fig. 2 is the organigram that air bag is arranged on the 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: the conducting port of lithium battery body 1 of the present invention is provided with positive pole ear 2 and negative lug 3.Simultaneously, lithium battery body 1 is provided with the pressure release assembly.
With regard to the present invention's one preferred implementation, in order effectively to take in the gas after bulging appears in lithium battery body 1, the pressure release assembly of employing is arranged on the side of lithium battery body 1.Certainly, consider the placement needs that can cooperate lithium battery body 1, the pressure release assembly of employing can also be arranged on the bottom of lithium battery body 1.Certainly, it is also passable that the pressure release assembly is arranged on the side of lithium battery body.And, need for some special application, can be provided with the pressure release assembly simultaneously in side and the bottom of lithium battery body 1 equally.
Further, consider the facility of the manufacturing, better consolidate fail safe simultaneously, pressure release assembly of the present invention is air bag 4.Simultaneously, body 1 mutual conduction of air bag 4 and battery.And influence is normal in order to prevent the unexpected damaged of air bag 4 to occur uses, and is provided with interlayer in the air bag 4 of employing.
By above-mentioned character express as can be seen, adopt the present invention after, the existence of the pressure release assembly that constitutes by air bag can effectively absorb the flatulence that the lithium battery body may occur in use.Thus, prevent the leakage of gas, improve the safe coefficient of using.Simultaneously, simple structure of the present invention is worthy to be popularized.
