Abstract
The utility model discloses a kind of lithium-ion battery module, including lithium ion battery, negative pole housing, positive pole termination, positive wire, negative wire, branch attic base, spacing bearing, piston, spring, steam vent and branch attic base passage, compared with prior art, the utility model is by piston under the force of a spring by the vent hole seal of positive pole termination, branch attic base is used for the position for maintaining the piston at steam vent, when lithium ion battery produces pressure, from exhaust outlet pressure release after pressure jack-up piston, then reset under the force of a spring, so as to play explosion-proof effect, prevent battery explosion or deformation, improve service life, value with popularization and application.
Description
Technical field
The utility model is related to a kind of battery, more particularly to a kind of lithium-ion battery module.
Background technology
Lithium ion battery：It is a kind of secondary cell (rechargeable battery), it relies primarily on lithium ion between a positive electrode and a negative electrode
Movement carrys out work.In charge and discharge process, Li+ comes and goes insertion and deintercalation between two electrodes：During charging, Li+ is de- from positive pole
It is embedding, negative pole is embedded in by electrolyte, negative pole is in rich lithium state；It is then opposite during electric discharge.Battery, which is typically used, contains elemental lithium
Material, as electrode, is the representative of modern high performance battery.In the prior art, the explosion-proof performance of lithium ion battery is relatively low, just in case
When there is the phenomenon overcharged, it may result in battery and heave, so as to cause battery to scrap or even explode, accordingly, there exist room for improvement.
Utility model content
The purpose of this utility model is that provides a kind of lithium-ion battery module to solve the above problems.
The utility model is achieved through the following technical solutions above-mentioned purpose：
The utility model include lithium ion battery, negative pole housing, positive pole termination, positive wire, negative wire, branch attic base,
Spacing bearing, piston, spring, steam vent and branch attic base passage, the lithium ion battery are located in the negative electrode casing body, described
Negative wire is connected between the negative pole of lithium ion battery and the negative pole housing, the positive wire be connected to positive pole termination with
Between the positive pole of lithium ion battery, the side of the positive pole termination is provided with steam vent, and the piston is located at the positive pole termination
It is interior, and at steam vent, the spring, the side of the branch attic base are set between the upper end of the piston and the positive pole termination
Edge is fixedly connected with the edge of the positive pole termination, and the middle part of the branch attic base sets the spacing bearing, the spacing bearing
Positioned at the lower end of the piston, the branch attic base passage is set on the branch attic base.
The beneficial effects of the utility model are：
The utility model is a kind of lithium-ion battery module, and compared with prior art, the utility model is by piston in bullet
By the vent hole seal of positive pole termination under the active force of spring, branch attic base is used to maintain the piston at the position of steam vent, when lithium from
When sub- battery produces pressure, from exhaust outlet pressure release after pressure jack-up piston, then reset under the force of a spring, so as to play
Explosion-proof effect, prevents battery explosion or deformation, improves service life, the value with popularization and application.
