Description
Technical field
The present invention relates to safety-type soft bag lithium ionic cell and electronic cigarette.
Background technology
The electronic cigarette battery flexible packing lithium ion battery that most commonly aluminum plastic film encapsulation forms at present.But lithium ion battery is organic bath, resultant battery is in the case where occurring the extreme cases such as acupuncture, foreign object impact, super-charge super-discharge, thermo-field thoery, contact wetting and oxygen, chemical reaction is produced in shell, produce a large amount of gases and heat, heat reaches the ignition point of organic electrolyte, result on fire, there is potential safety hazard.Particularly, even if causing battery abnormal without external cause, for aluminum plastic film during long-term put, moisture and oxygen in environment will will slowly penetrate inside battery according to diffusion principle, so also necessarily cause battery abnormal, there is potential safety hazard.
Another lithium ion battery, using the cylindrical steel shell structure of similar Ni-MH battery etc..The anti-water percolating capacity of box hat is better than aluminum plastic film, but the greatest danger is to cause to explode when internal pressure can not release in time.Security consideration is waited for explosion-proof, block is by top cover, CID (current interrupt
Device, failure of current device), burst disk, PTC (Positive
Temperature
Coefficient, positive temperature coefficient) thermistor and cushion rubber composition, when battery is abnormal, internal pressure reaches opening pressure (common is 0.8~1.5MPa), then expendable disconnection occurs for CID, battery performance loop is cut off, if battery is still in a large amount of aerogenesis and warm, when internal pressure reaches Opening pressure (common is 1.8~2.5MPa), then burst disk, which is torn, reaches pressure release effect.Common such battery is the cylinder type lithium batteries such as 13450,14500 and 18650.The block opening pressure and Opening pressure of such battery are too high, then internal pressure can not release in time when battery occurs abnormal, and explosion-proof capabilities are poor.But opening pressure and Opening pressure are too low, then it is easy to battery occurs in production process to be disconnected or pressure release, causes battery to scrap, manufacturing cost is too big.
And electronic cigarette is personal storage and used, once it is on fire, great threat will be caused to the person and property safety, therefore there is an urgent need to develop safer electronic cigarette.
In addition, the electro-hydraulic health for easily leaking, endangering consumer when internal lithium ion battery occurs abnormal.
The content of the invention
It is a primary object of the present invention to provide a kind of safety-type soft bag lithium ionic cell and electronic cigarette, to overcome the security hidden trouble present in prior art.
The technical scheme is that：A kind of safety-type soft bag lithium ionic cell, it includes：As the steel casing assembly of outer layer shell, being placed in the plastic-aluminum putamina as internal layer shell, the battery core being placed in the plastic-aluminum putamina, the battery core in steel casing assembly includes positive and negative electrode lug；The steel casing assembly includes housing, positive terminal, negative terminal, insulated enclosure pad, also include safety valve, the safety valve is arranged on the positive terminal, the positive pole ear is connected with the positive terminal spot welding, the negative lug is connected with the negative terminal spot welding, and the positive terminal and the negative pole end pass through the insulated enclosure pad.
Preferably, the present invention can also have following technical characteristic：
The battery core includes square Soft Roll lithium-ion electric core and cylindrical type Soft Roll lithium-ion electric core.
The steel casing assembly includes square box hat housing and cylindrical steel housing.
The present invention also provides a kind of electronic cigarette, including suction nozzle, battery and atomizer, and the battery is using safety-type flexible package ion battery of the invention.
Compare prior art; because the new safety-type soft bag lithium ionic cell of the present invention had both included the internal layer shell of aluminum plastic film; include outer steel shell casing assembly again; provide inside and outside two layers of housing protection; soft bag lithium ionic cell security performance is improved, internal layer aluminum plastic film is solved and easily scratches the safety problems such as discouraged leakage because material is soft.Due to being provided with the safety valve of a low Opening pressure on shell positive terminal; effectively completely cut off extraneous air to contact with organic bath into housing is interior; also effectively prevent it is electro-hydraulic when internal lithium ion battery occurs abnormal leak, protect consumer's health to avoid contact to electro-hydraulic pollution.
Brief description of the drawings
Fig. 1 is the structural representation of the square safety-type soft bag lithium ionic cell of embodiment one.
Embodiment
Embodiment one：
Referring to Fig. 1, for the structural representation of square safety-type soft bag lithium ionic cell, it includes：Square steel casing assembly 10, as the outer layer shell of battery, the plastic-aluminum putamina 20 being placed in square steel casing assembly, as the internal layer shell of battery, battery core 30.
The battery core includes positive pole ear 31 and negative lug 32.
The square steel casing assembly 10 includes square box hat shell 11, positive terminal 12, negative terminal 13, insulated enclosure pad 14 and safety valve 15.The positive pole ear 31 of electronic cigarette battery is connected with the spot welding of positive terminal 12, and the negative lug 32 of electronic cigarette battery is connected with the spot welding of negative terminal 13, and the safety valve 15 is arranged on positive terminal 12, and positive terminal 12 and negative terminal 13 pass through insulated enclosure pad 14.
