Description
Technical field
The present invention relates to a kind of lithium battery and its application product with fireproof anti-explosion device, in particular, it is related to
A kind of lithium battery with fireproof anti-explosion device and the electric car using the battery.
Background technology
Because non-renewable energy resources crisis and environmental pollution are serious, the whole world accelerates the hair of green high-performance lithium battery
Exhibition, the application field of lithium battery extend to the fields such as traffic power, energy storage, space flight, communication spare power supplies by digital product field,
People also develop into up to a hundred or even thousands of ampere-hours to the demand of lithium battery by hundreds of original MAHs, with carrying for capacity
Rising, safety problem is it will be more difficult to control, therefore high-capacity lithium battery security is the problem of numerous enterprises research now, if
It can resolve that lithium battery is on fire, explode this global problem, the application of lithium battery will enter faster wider array of developing stage.
Publication No. CN102044715A invention disclosed a kind of explosion-proof equipment of lithium battery on May 4th, 2011, and it includes lithium battery
Structure including housing, positive electrode, negative electrode, sheet rubber, lithium battery casing are provided with passage, covered on passage and fixed
There is sheet rubber, the thickness of sheet rubber is 0.5-5mm.Due to using sheet rubber as explosion-proof valve, without open up in addition liquid injection hole to
Injection electrolyte and nitrogen, liquid injection hole and explosion-proof valve are integrated, simple in construction, cost is low, operation easy to process in battery
Simply；In use, only need to inwardly inject electrolyte and nitrogen through sheet rubber with needle tubing, after extracting syringe needle, sheet rubber is utilized
Enclosed elastic pin hole, reaches electrolyte and nitrogen does not leak, lithium battery normal work.The invention is applied to variously-shaped and not
The lithium battery of stack pile.But lithium battery occur blast mainly due to short circuit, because overcharging or environment temperature is too high leads
The reasons such as the radiating of cause is not smooth cause so-called " thermal runaway " problem, " thermal runaway " and then trigger inner pressure of battery to increase severely, so as to cause
Blast, therefore prevent lithium battery blast from not only to drain internal pressure in time, it should also start with from temperature control link, many-side, which is taken, arranges
The explosion-proof target of lithium battery could more effectively be reached by applying, and the invention is only laid particular emphasis on by passage and explosion-proof valve pressure release, and
It is not to use more fully safeguard procedures, therefore it is relatively limited to produce effects.
The content of the invention
Lithium battery easily because short circuit, radiating is bad the problems such as cause blast on fire, and existing lithium battery is fire-proof and explosion-proof arranges
Applying limitedly can only improve subproblem and be unable to comprehensively solve problem, and to overcome this defect, the invention provides a kind of pin
The blast origin cause of formation on fire to lithium battery strengthens the lithium battery fireproof anti-explosion device of fire-proof and explosion-proof function.
The technical scheme is that：A kind of lithium battery with fireproof anti-explosion device, the lithium battery include battery core group,
Battery core sheath and shell, battery core group are placed in battery core sheath, and battery core sheath is placed in shell, in the gap of battery core sheath and shell
Filled with the endothermic reaction can occur and produce the fire extinguishing material of carbon dioxide, inner surface of outer cover is provided with heat insulation layer, battery core sheath with
Damping fire proofing is filled with the gap of battery core group, shell is provided with dredging hole.The present apparatus is for lithium battery blast on fire
Mechanism carries out dependent response formula work, i.e., by the rise of lithium battery electric core temperature, fire extinguishing material is reacted, on the one hand go out
Absorbed heat during fiery material reaction, the heat absorption that lithium battery is generated, play and suppress temperature quickly elevated effect, inside digestion
While heat energy, heat insulation layer can control the heat energy from outside batteries environment to input；On the other hand, material reaction of putting out a fire is utilized
The carbon dioxide of generation progressively squeezes the oxygen of inside battery, eliminates the key element for supporting that battery core is burnt, and suppresses so as to reach
The purpose of burning；Furthermore using put out a fire material absorbing and cooling temperature while by dredging hole by original air in shell and after
Carbon dioxide to generate is discharged in time, keeps inner pressure of battery stable in a level of security；In addition, damping fire proofing can be with
The external impact that battery carrier introduces by residing poor environment is slackened, the stabilization of battery core group is preferably kept, avoids because acutely
Vibrations cause short circuit, while the fire resistance of damping fire proofing also contributes to prevent unexpected battery core group harm on fire from expanding
Change.By above-mentioned measure, the present apparatus can effectively prevent lithium battery blast on fire, greatly improve lithium battery safety in utilization.Go out
Fiery material can be a kind of composition, react generation carbon dioxide by selfdecomposition.
Preferably, the dredging hole is provided with relief valve, relief valve includes valve body and active valve block, screw thread on valve body opening

On valve block, the other end is connected to bonnet bottom surface, and stage clip circle circle external diameter is more than central through hole diameter.In its natural state, moving valve
Block is extruded by stage clip, is pressed in valve pocket, blocks valve pocket.When enclosure air pressure increases, active valve block is eventually because outer
Pressure differential inside and outside shell and opened by outside top, release the closure to valve pocket so that the excessive pressure of enclosure is released,
Ensure that inner pressure of battery is in safer level, reduce risk of explosion.Another aspect relief valve enters when being also battery assembling
Enter the passage that leaks of a small amount of air of enclosure, under the exclusion for the carbon dioxide being continuously generated in shell, original air by
Step is drained, and in the absence of oxygen, the battery core group of battery will not burn, so as to play fire-retardant fireproof effect.
Preferably, described fire extinguishing material is bicarbonate.Bicarbonate may occur from decomposition reaction when heated, generate
Carbon dioxide, and this reaction is the endothermic reaction, meets the need of work of the present apparatus.It is fire extinguishing material from bicarbonate,
