Abstract
The invention discloses a lithium battery. The lithium battery comprises a shell, a puncturing plate and a pressure limiting plate, wherein the pressure limiting plate is arranged in the middle upper part of the shell; the puncturing plate is arranged in the shell below the pressure limiting plate; and an exhausting hole is formed in the shell above the pressure limiting plate. The invention aims to improve the safety of the lithium battery. According to the lithium battery disclosed by the invention, the puncturing plate and the pressure limiting plate arranged in the shell are adopted; when the internal pressure of the pressure limiting plate is overhigh, the pressure limiting plate is punctured by the puncturing plate to release gas, so that the safety of the lithium battery is ensured, and the shell of the lithium battery is effectively prevented from being damaged so as to avoid electrolyte leakage, environmental pollution and other accidents.
Description
Technical field
The present invention relates to a kind of battery, particularly a kind of lithium battery.
Background technology
In order to improve the safety of lithium battery, explosion-proof line is generally set on housing, lithium battery intrinsic pressure too high time, explosion-proof line breaks thus reaching release gas, prevent the danger that lithium battery explodes, the application of this explosion-proof line can cause that housing is damaged, it may occur that battery leakage is thus the process for battery makes troubles and also pollutes the environment.
Summary of the invention
For solving the problems referred to above, the invention discloses a kind of lithium battery, by arranging thorn plate and pressure limiting plate in the enclosure so that pressure limiting plate intrinsic pressure too high time stung plate and punctured release gas, while ensureing lithium battery safety, also efficiently avoid the breakage of li battery shell.
Lithium battery disclosed by the invention, including shell, thorn plate and pressure limiting plate, described pressure limiting plate arranges middle and upper part in the enclosure, and described thorn plate is arranged in the shell below pressure limiting plate, and the described shell above pressure limiting plate is provided with steam vent.Lithium battery disclosed by the invention, by the thorn plate arranged and pressure limiting plate, pressure limiting plate is punctured by stinging plate when cell internal pressure is too high, gases at high pressure in shell are discharged by the steam vent then passed through on shell, li battery shell breakage is also avoid ensureing, it is to avoid contaminated environment and etching apparatus while lithium battery uses safety.
A kind of improvement of lithium battery disclosed by the invention, also sets up sealing ring between described pressure limiting plate and outer casing inner wall, described pressure limiting plate and sealing ring are tightly disposed in shell.This improvement, by the sealing ring arranged, improves the seal between pressure limiting plate and outer casing inner wall, effectively prevent the leakage filling material in lithium battery, also improve the sensitivity to lithium battery interior pressure of the pressure limiting plate while improve lithium battery safety in utilization.
Another of lithium battery disclosed by the invention is improved, and described thorn plate includes being sealingly disposed in the pressure plare of pressure limiting plate lower end and being arranged on the spine at pressure plare center.The thorn plate simple in construction that this improvement is arranged, cell internal pressure reflection is sensitive, thus being effectively improved the safety that lithium battery uses.
Lithium battery disclosed by the invention passes through the pressure limiting plate of setting, stings plate and be arranged on the sealing ring between pressure limiting plate and outer casing inner wall, improve the sealing of lithium battery, prevent the leakage of lithium battery interior filler, prevent battery case damaged while improving battery anti-explosion performance, efficiently avoid lithium battery fault after stain and corrosive environment, reduce the post-processing difficulty of lithium battery.

1, shell, 2, thorn plate, 3, pressure limiting plate, 4, sealing ring.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, it is further elucidated with the present invention, it should be understood that following detailed description of the invention is merely to illustrate the present invention rather than restriction the scope of the present invention.
As shown in Figure 1, lithium battery disclosed by the invention, including shell 1, thorn plate 2 and pressure limiting plate 3, described pressure limiting plate 3 is arranged on the middle and upper part in shell 1, described thorn plate 2 is arranged in the shell 1 below pressure limiting plate 3, and the described shell 1 above pressure limiting plate 3 is provided with steam vent.Lithium battery disclosed by the invention, by the thorn plate arranged and pressure limiting plate, pressure limiting plate is punctured by stinging plate when cell internal pressure is too high, gases at high pressure in shell are discharged by the steam vent then passed through on shell, li battery shell breakage is also avoid ensureing, it is to avoid contaminated environment and etching apparatus while lithium battery uses safety.
Preferred as one, also set up sealing ring 4 between described pressure limiting plate 3 and shell 1 inwall, described pressure limiting plate 3 and sealing ring 4 are tightly disposed in shell 1.By the sealing ring arranged, improve the seal between pressure limiting plate and outer casing inner wall, effectively prevent the leakage filling material in lithium battery, while improve lithium battery safety in utilization, also improve the sensitivity to lithium battery interior pressure of the pressure limiting plate.
Preferred as one, described thorn plate 2 includes being sealingly disposed in the pressure plare of pressure limiting plate 3 lower end and being arranged on the spine at pressure plare center.By the thorn plate simple in construction arranged, cell internal pressure reflection is sensitive, thus being effectively improved the safety that lithium battery uses.
Lithium battery disclosed by the invention passes through the pressure limiting plate of setting, stings plate and be arranged on the sealing ring between pressure limiting plate and outer casing inner wall, improve the sealing of lithium battery, prevent the leakage of lithium battery interior filler, prevent battery case damaged while improving battery anti-explosion performance, efficiently avoid lithium battery fault after stain and corrosive environment, reduce the post-processing difficulty of lithium battery.
