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 the pollution of minimizing and the environment day by day of petroleum resources is day by day serious, protect environment, energy-saving and emission-reduction
Trend the most in the world and trend are become.In this context, in recent years, based on battery
Want power source or partial power source electric vehicle (mainly include hybrid electric vehicle, plug-in
Hybrid electric vehicle, pure electric vehicle) engender and increasing, the carbon emission amount of electric vehicle
It is less than traditional combustion engine automobile, the carbon emission of pure electric vehicle even zero, and there is energy
The feature that conversion efficiency is high, this makes people that electric automobile be considered as following replacement diesel locomotive
One important selection.
The power of current electric automobile mainly selects lithium ion battery bag, and lithium ion battery bag is by multiple
Lithium-ion battery monomer is constituted, carrying out the design of battery bag when, if using relatively low capacity
Lithium-ion battery monomer, then the connection between lithium-ion battery monomer is more complicated, BMS(electricity
Pond management system) design the most more complicated；And if using the lithium ion battery of larger capacity
Monomer, then the connection between lithium-ion battery monomer is more convenient, and the design of BMS system is the most relative
Simply.The lithium-ion battery monomer of relatively low capacity mentioned here, is primarily referred to as traditional 1865
The conventional lithium ion battery monomers such as 0 type, 26650 types, they typically store energy less than 10Wh.
And high capacity lithium ion battery monomer is primarily referred to as the bigger Soft Roll or the box hat that occur in recent years
Rectangular cell monomer, they typically store energy more than 10Wh.
But first existing jumbo lithium-ion battery monomer has the disadvantage that, it stores energy
More, once break down, after only needing several even one battery cells just can cause seriously
Really, secondly, under conditions of overcharging or excessively putting, high capacity lithium ion battery monomer is easily sent out
Raw overheated, and in the case of puncturing, after substantial amounts of electrolyte overflows ingress of air rapidly,
High capacity lithium ion battery monomer may even happen that the situations such as blast on fire.
Part producer is had to use the little battery cell that multiple parallel connection is set in a battery container, from
And constitute the way of a big battery cell, but this way is easily caused enclosure interior
Generate heat uneven between battery cell thus cause thermal runaway.Further, this way equally can not gram
Take the explosion issues on fire in the case of above-mentioned puncture.
[summary of the invention]
It is an object of the invention to provide the high capacity lithium ion battery that a kind of safety is high.
For above-mentioned purpose, the technical solution used in the present invention is:
A kind of high capacity lithium ion battery, it includes the housing of overall liquid-tight envelope, is arranged on described housing
In multiple battery cells, be positioned at two collectors, positive output pole and the negative output pole of housing
, wherein the both positive and negative polarity of battery cell is connected with a collector respectively, described positive output pole
It is electrically connected with a collector respectively with negative output pole, in housing, is 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 junction 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 junction point of collector
, positive output pole and negative output extremely on be provided with ptc material or fuse.
As preferred technical scheme: be provided with pressure valve on described housing.
As preferred technical scheme: be provided with copper sealing coat between described battery cell.
As preferred technical scheme: be provided with compound insulation layer, institute between described battery cell
The compound insulation layer stated is wrapped up in paraffin by copper-clad and is constituted.
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 uses perfusion flame-resistant insulation liquid in the cell housing, and the infiltration of multiple battery cells is in insulation
In fire resistant fluid, so that the temperature between battery cell is kept in balance, it is unlikely appearance internal
Focus thus cause thermal runaway, it addition, in this case, even if piercing through the thing of battery
Therefore, the electrolyte of battery cell is surrounded by flame-resistant insulation liquid after overflowing, it is impossible to ingress of air,
Fire accident will not be caused；Even if the flare having the external world enters into enclosure interior, flame-resistant insulation liquid
After volatilization of being heated, it is also possible to play the effect of fire extinguishing.So, the high-capacity lithium of the present invention from
Sub-battery has the effect of Large Copacity and high safety.It addition, by flame-resistant insulation liquid in housing
Liquid level arranges the junction point of the both positive and negative polarity higher than battery cell and collector.Due at junction point
It is usually the place that the bigger heating of electric current is bigger, is also the place being prone to accidents, so will
The liquid level of flame-resistant insulation liquid is arranged
Higher than junction point, further assure that the safety of whole high capacity lithium ion battery.Finally, exist
Positive output pole and negative output extremely on be provided with ptc material or fuse, work as high-capacity lithium-ion
Battery occurs abnormal, such as, the when of having abnormal High-current output, ptc material can be become by thermal resistance
Greatly, thus reaching the purpose of current limliting, fuse then can occur fusing thus turn-off current, more
Add the safety improving whole high capacity lithium ion battery.
In one of preferred technical scheme, housing is provided with pressure valve, when high-capacity lithium from
The when that sub-cell internal pressure being excessive, release can be carried out by pressure valve, prevent inside
Pressure is excessive to set off an explosion.
In one of preferred technical scheme, between described battery cell, it is provided with copper sealing coat.
Copper is the excellence conductor of heat, and adding copper sealing coat can be further such that temperature between battery cell
Degree is kept in balance, on the other hand, when an accident occurs, such as have hard thing thrust high-capacity lithium from
The when of sub-battery, copper sealing coat can stop hard thing so that hard thing is difficult to run through whole great Rong
Amount lithium ion battery.So can improve high capacity lithium ion battery further when being punctured
Safety.
In one of preferred technical scheme, between described battery cell, it is provided with compound insulation layer
, described compound insulation layer is wrapped up in paraffin by copper-clad and is constituted.Paraffin is a kind of phase-change material, is being subject to
Can absorb heat during heat and become liquid, use copper-clad to wrap up in paraffin, can have above-mentioned copper sealing coat
Advantage, it is also possible to absorb the heating of battery cell further with paraffin liquefaction, so that whole
Individual high capacity lithium ion battery is under good temperature conditions and is operated.
