Description
[technical field]
The present invention relates to a kind of lithium ion battery, especially, relate to a kind of jumbo lithium ion battery.
[background technology]
Along with petroleum resources day by day reduce and the pollution of environment day by day serious, protection of the environment, energy-saving and emission-reduction have become current trend and trend in the world.Under this background, in recent years, the motor vehicle that the battery of take is main power source or partial power source (mainly comprises hybrid electric vehicle, plug-in hybrid electric vehicle, pure electric vehicle) engender and increasing, the carbon emission amount of motor vehicle is less than traditional combustion engine automobile, and the carbon emission of pure electric vehicle is even zero, and have the advantages that energy conversion efficiency is high, this makes people electric automobile is considered as to an important selection of following replace internal combustion engines car.
The power of current electric automobile is mainly selected lithium ion battery bag, lithium ion battery bag consists of a plurality of lithium-ion battery monomers, when carrying out power brick design, if adopted compared with the lithium-ion battery monomer of low capacity, the connection more complicated between lithium-ion battery monomer, BMS(battery management system) design is more complicated also; And if adopt the lithium-ion battery monomer of larger capacity, the connection between lithium-ion battery monomer is more convenient, the design of BMS system is also relatively simple and easy.Here said compared with the lithium-ion battery monomer of low capacity, mainly refer to traditional lithium-ion battery monomers such as 18650 traditional types, 26650 types, their general storage power are less than 10Wh.And high capacity lithium ion battery monomer mainly refers to larger Soft Roll or the box hat rectangular cell monomer occurring in recent years, their general storage power are greater than 10Wh.
But existing jumbo lithium-ion battery monomer has following shortcoming: first, its storage power is more, once break down, only need several even battery cells just can cause serious consequence, secondly, overcharging or crossing under the condition of putting, it is overheated that high capacity lithium ion battery monomer easily occurs, and the in the situation that of puncture, at a large amount of electrolyte, overflow rapidly after ingress of air, even may there is the situations such as blast on fire in high capacity lithium ion battery monomer.
Have part producer to adopt the little battery cell of a plurality of parallel connections be set in a battery container, thereby form the way of a large battery cell, thus but this way easily causes generating heat between the battery cell of enclosure interior the inhomogeneous thermal runaway that causes.And this way can not overcome the blast problem on fire in above-mentioned puncture situation equally.
[summary of the invention]
The object of this invention is to provide a kind of safe high capacity lithium ion battery.
For above-mentioned purpose, the technical solution used in the present invention is:
A kind of high capacity lithium ion battery, it comprises the housing of whole liquid sealing, be arranged on a plurality of battery cells in described housing, be positioned at two collectors of housing, the positive output utmost point and the negative output utmost point, wherein the both positive and negative polarity of battery cell is connected with a collector respectively, the described positive output utmost point and the negative output utmost point are electrically connected with a collector respectively, in housing, be perfused with flame-resistant insulation liquid, the liquid level of described flame-resistant insulation liquid is higher than the both positive and negative polarity of battery cell and the tie point of collector, the liquid level of described flame-resistant insulation liquid is higher than the both positive and negative polarity of battery cell and the tie point of collector, in the positive output utmost point and negative output, be provided with ptc material or fuse on extremely.
As preferred technical scheme: be provided with pressure valve on described housing.
As preferred technical scheme: be provided with copper separator between described battery cell.
As preferred technical scheme: be provided with compound insulation layer between described battery cell, described compound insulation layer is wrapped up in paraffin by copper-clad and formed.
As preferred technical scheme: described flame-resistant insulation liquid is silicone oil.
As preferred technical scheme: described flame-resistant insulation liquid is fire resistant oil.
The present invention adopts and in battery container, pours into flame-resistant insulation liquid, a plurality of battery cells infiltrate in flame-resistant insulation liquid, thereby the temperature between battery cell is kept in balance, thereby be unlikely, occur that inner focus causes thermal runaway, in addition, in this case, even if pierce through the accident of battery, the electrolyte of battery cell is surrounded by flame-resistant insulation liquid after overflowing, can not ingress of air, can not cause accident on fire; Even if there is extraneous flare to enter into enclosure interior, flame-resistant insulation liquid, after the volatilization of being heated, can also play the effect of fire extinguishing.So high capacity lithium ion battery of the present invention has the effect of large capacity and high safety.In addition, by the liquid level setting of flame-resistant insulation liquid in housing higher than the both positive and negative polarity of battery cell and the tie point of collector.Owing to being generally the larger place of the larger heating of electric current at tie point place, be also the place being prone to accidents, so by the liquid level setting of flame-resistant insulation liquid higher than tie point, guarantee further the safety of whole high capacity lithium ion battery.Finally, in the positive output utmost point and negative output, be provided with ptc material or fuse on extremely, when high capacity lithium ion battery occurs abnormal, for example, when having abnormal High-current output, ptc material is subject to thermal resistance can become large, thereby reach the object of current limliting, thereby can there is fusing turn-off current, the fail safe that more improves whole high capacity lithium ion battery in fuse.
In one of preferred technical scheme, on housing, be provided with pressure valve, when high capacity lithium ion battery internal pressure is excessive, can carry out release by pressure valve, prevent from that internal pressure is excessive to set off an explosion.
In one of preferred technical scheme, between described battery cell, be provided with copper separator.Copper is hot excellence conductor, add copper separator can further make the temperature between battery cell keep in balance, on the other hand, when having an accident, for example, when having hard thing to thrust high capacity lithium ion battery, copper separator can stop hard thing, makes hard thing be difficult for running through whole high capacity lithium ion battery.Can further improve the fail safe of high capacity lithium ion battery when being punctured like this.
In one of preferred technical scheme, between described battery cell, be provided with compound insulation layer, described compound insulation layer is wrapped up in paraffin by copper-clad and is formed.Paraffin is a kind of phase-change material, when being heated, can absorbing heat and become liquid, adopt copper-clad to wrap up in paraffin, can there is above-mentioned copper separator, can also further utilize paraffin liquefaction to absorb the heating of battery cell, thereby make whole high capacity lithium ion battery under good temperature conditions, carry out work.
