Abstract

The utility model discloses a soft package lithium ion power battery with pressure relief and explosion-proof functions and relates to a power battery. The soft package lithium ion power battery comprises a battery body (2) and a safety valve (1), wherein the safety valve (1) is arranged on the battery body (2), one end of the safety valve (1) is arranged in the battery body (2), the other end of the safety valve (1) is arranged outside the battery body (2), a pressure relief hole is formed in the safety valve (1), and a pressure display device (3) and an alarm device (4) are respectively arranged on the outer side surfaces of the battery body (2). The soft package lithium ion power battery provided by the utility model has the advantages of simple structure and strong practicality, and can effectively solve the problems of bulging and liquid leakage of the soft package battery and prevent the explosion possibility of the soft package lithium ion power battery under short-circuit, acupuncture and other non-normal states.

Description

A kind of method for soft package lithium ion power with pressure release, explosion prevention function
[technical field]
The utility model relates to a kind of electrokinetic cell, especially relates to a kind of method for soft package lithium ion power with pressure release, explosion prevention function.
[background technology]
Known, along with the development of lithium-ion electric pool technology is increasingly mature, electric automobile, UPS, the industries such as energy-accumulating power station also increase gradually to the demand of lithium ion battery, but be directed at present lithium ion battery, its security performance is a very important link, this is also a key factor of restriction lithium ion battery development, current method for soft package lithium ion power in use, inside battery can produce gas, cause inside battery air pressure to increase gradually, often occur that battery bulging is existing, leakage, the phenomenons such as aluminum plastic film bursts, What is more causes battery to be blasted because cell internal pressure is excessive when non-normal use, people or thing around sustained damage.
[summary of the invention]
In order to overcome the deficiency in background technology, the utility model discloses a kind of method for soft package lithium ion power with pressure release, explosion prevention function, the utility model is by the battery body of method for soft package lithium ion power, safety valve being set, and with this, reaches pressure release, explosion-proof object.
In order to realize described utility model object, the utility model adopts following technical scheme:
A kind of method for soft package lithium ion power with pressure release, explosion prevention function, comprise battery body and safety valve, on battery body, be provided with safety valve, one end of safety valve is arranged on battery body inside, the other end of safety valve is arranged on battery body outside, described safety valve is provided with bleeder port, is respectively equipped with pressure display unit and alarm on the lateral surface of battery body.
Described battery body is method for soft package lithium ion power.
Owing to having adopted technique scheme, the utlity model has following beneficial effect:
A kind of method for soft package lithium ion power with pressure release, explosion prevention function described in the utility model, comprises battery body and safety valve, by the battery body of method for soft package lithium ion power, safety valve being set, with this, reaches pressure release, explosion-proof object; The utility model is simple in structure, practical, effectively solved the problem of soft-package battery bulging, leakage, prevented that method for soft package lithium ion power from blasting under the abnormal conditions such as short circuit, acupuncture may, extended the method for soft package lithium ion power life-span during normal use.
[accompanying drawing explanation]
Fig. 1 is the utility model perspective view.
In figure: 1, safety valve; 2, battery body; 3, pressure display unit; 4, alarm.
[embodiment]
Explanation the utility model that can be detailed by the following examples, open the purpose of this utility model is intended to protect all technological improvements within the scope of the utility model.
A kind of method for soft package lithium ion power with pressure release, explosion prevention function described in 1 by reference to the accompanying drawings, comprise battery body 2 and safety valve 1, on battery body 2, be provided with safety valve 1, one end of safety valve 1 is arranged on battery body 2 inside, the other end of safety valve 1 is arranged on battery body 2 outsides, described safety valve 1 is provided with bleeder port, is respectively equipped with pressure display unit 3 and alarm 4 on the lateral surface of battery body 2.
Described battery body 2 is method for soft package lithium ion power.
Implement a kind of pressure release that has described in the utility model, the method for soft package lithium ion power of explosion prevention function, when work, first the safe atmospheric pressure value of safety valve 1 is set, pressure display unit 3 on battery body 2 lateral surfaces can clearly demonstrate the pressure in battery, when the air pressure of battery body 2 reaches set point, safety valve 1 is automatically opened and is carried out pressure release work, pressure release after hours safety valve 1 is closed automatically, when battery body 2 runs into non-normal use, alarm 4 on battery body 2 first gives the alarm, safety valve 1 on battery body 2 can eject moment fast afterwards, carry out quick pressure releasing, prevent that battery body 2 from blasting.
The utility model does not describe part in detail for prior art.
