Description
Technical field
The utility model is related to field of batteries, and in particular to a kind of lithium battery steel shell with discharging slot.
Background technology
Lithium battery is due to its superior high current, high power and good property at high and low temperature, more and more by wide
Big producer and the welcome of client.The security performance of the lithium battery of Large Copacity is poor, especially in abuse conditions, in lithium battery
Portion's pressure can be sharply increased, and easily cause lithium battery burning, blast, or even can also cause personal injury, so lithium battery needs peace
Release entirely, to ensure the safe handling of lithium battery.There are problems in the safety relief device of current battery, for example, be designed to glass
The weak link of glass envelope, exists and releases pressure inaccurately, while also there is the problem of causing electro-hydraulic leakage；And in the box hat of battery
Weak link is carved in upside, there is also more internal cell volume is taken, and causes battery to utilize the reduction in space, causes battery
Capacity reduction, meanwhile, because the box hat of lithium battery is generally adopted by cylinder and the separated housing of bottom plate at present, housing
Thickness is 0.5mm, and it is yielding that weak link back casing is carved in such side.
The content of the invention
The purpose of this utility model is let out to overcome the weak point that above-mentioned prior art is present, and provide one kind to have
The lithium battery steel shell of groove is put, it is easy to use, simple to operate, be easy to large-scale promotion application.
The technical solution adopted in the utility model is：A kind of lithium battery steel shell with discharging slot, including main body, release
Groove, positive electrode cap and outer steel shell, described main body upper end are provided with positive electrode cap, and described positive electrode cap is surrounded by groove, and described is recessed
Discharging slot, described discharging slot connection exhaust emission valve, described exhaust emission valve connection safety valve, described peace are provided with groove
Full valve is connected on inner vent, described positive electrode cap connection battery core, described battery core connection conductive component, described conductive component
Portion is provided with waterproof layer, and described conductive component lower end is provided with seal washer, and described battery core bottom is provided with anti-corrosion layer, described
Anti-corrosion layer lower end is provided with negative pole cap, and described negative pole cap connection outer steel shell, described outer steel shell is provided with mounting groove.
Described discharging slot more than one.
Described discharging slot is centered around positive cover into symmetry angle.
Described discharging slot is opened in the top of outer steel shell 14.
A diameter of 0.4-0.8mm of described discharging slot.
The beneficial effects of the utility model are：The utility model is when lithium battery abuse causes its internal pressure excessive, originally
Utility model can release out the pressure of lithium battery interior, reduce safety issue of the lithium battery caused by abuse, can be effective
Solve bad battery of the lithium battery caused by battery safety device, failure and security problems.
Brief description of the drawings
Fig. 1 is the utility model internal structure schematic diagram.
Fig. 2 is the utility model main structure diagram.
Embodiment
Accompanying drawing being given for example only property explanation, it is impossible to be interpreted as the limitation to this patent；It is attached in order to more preferably illustrate the present embodiment
Scheme some parts to have omission, zoom in or out, do not represent the size of actual product；To those skilled in the art,
Some known features and its explanation may be omitted and will be understood by accompanying drawing.
With reference to each figure, a kind of lithium battery steel shell with discharging slot, including main body, discharging slot 1, positive electrode cap 2 and outer steel shell
14, described main body upper end is provided with positive electrode cap 2, and described positive electrode cap 2 is surrounded by be provided with groove 15, described groove 15 and let out
Put groove 1, the described connection exhaust emission valve 7 of discharging slot 1, the described connection safety valve 4 of exhaust emission valve 7, described safety valve 4
Connect inner vent 5, the described connection battery core 9 of positive electrode cap 2, the described connection conductive component 8 of battery core 9, described conductive component 8
Top is provided with waterproof layer 3, and the described lower end of conductive component 8 is provided with seal washer 6, and the described bottom of battery core 9 is provided with anti-corrosion layer
11, the described lower end of anti-corrosion layer 11 is provided with negative pole cap 10, the described connection outer steel shell 14 of negative pole cap 10, described outer steel shell 14
It is provided with mounting groove 13.
The described more than one of discharging slot 1.
Described discharging slot 1 is centered around positive cover into symmetry angle.
Described discharging slot 1 is opened in the top of outer steel shell 14.
A diameter of 0.4-0.8mm of described discharging slot 1.
Specific implementation process is as follows：When battery is in the case of abuse, puts as crossed or be short-circuit, battery temperature rise,
Internal pressure increases, small due to that can bear big pressure ratio other parts at discharging slot 1 after pressure exceedes desired setting value,
Pressure is easily leaked at discharging slot 1, is reduced the pressure of inside battery, security is guaranteed.
In figure, position relationship being given for example only property explanation is described, it is impossible to be interpreted as the limitation to this patent；Obviously, this reality
The utility model example is only intended to clearly illustrate with new above-described embodiment, and is not to the utility model
Embodiment restriction.For those of ordinary skill in the field, it can also make on the basis of the above description
Other various forms of changes or variation.There is no necessity and possibility to exhaust all the enbodiments.It is all new in this practicality
Any modifications, equivalent substitutions and improvements made within the spirit and principle of type etc., should be included in the utility model right will
Within the protection domain asked.
