Description

A kind of high security lithium ion battery
Technical field
The present invention relates to a kind of lithium ion battery pack system, a kind of battery pack system that ensure that lithium ion battery safety.
Background technology
Lithium ion battery owing to having that voltage is high, energy density big, have extended cycle life and the advantage such as good high and low temperature discharge performance, the most increasingly paid close attention to by each side, especially under the background that nowadays energy shortage problem becomes increasingly conspicuous, lithium ion battery for dynamical system is generally used in the fields such as automobile, aviation, boats and ships, and in this correspondence is that the step that battery uses is not caught up with in the development of security technology of Li-ion batteries piles.
And owing to using environment to become increasingly complex, the factor of its initiation lithium ion battery safety problem is the most diversified, does not only has the internal battery pack reason such as abuse, short circuit, also has the reason such as external physical impact and thermal shock.Existing Li-ion batteries piles security technology seldom has can more comprehensively tackle the various unsafe factors that battery is in use run into.
CN 200880127749 discloses a kind of chemical cell heat management system: it utilizes boiling point to be higher than room temperature (25 DEG C) and the evaporation of the non-aqueous insulation heat-transfer fluid less than 80 DEG C and condensation, takes away the heat that set of cells produces;The most this kind of heat-transfer fluid is the most nonflammable, therefore, it is possible to the suppression issuable intensity of a fire of internal battery pack to a certain extent.But set of cells is being impacted by external physical or heat when, it is possible that battery-pack exterior casing deformation fracture, heat-conducting fluid is revealed, and ultimately results in the security implementations inefficacy of set of cells.Further, heat-conducting fluid is not special extinguishing chemical, it is impossible to have good extinguishing effect.
CN 201310117800 discloses a kind of lithium-ion-power cell group installing fire-retardant Super-conductive conduit additional; in set of cells, monomer gap is equipped with the metal tube of band coolant; rupture when metal tube is by external impacts when; make coolant release fast endothermic volatilization in pipe, to reach set of cells is carried out the effect of safeguard protection.But lithium ion battery may simply be smoldered thermal runaway when, leakage and burning, it is not necessary to blast can be occurred to produce external impacts, it is thus possible to the safety protecting mechanism of Li-ion batteries piles will not be triggered.And coolant is mainly the safety being protected lithium ion battery by cooling, fire extinguishing effectiveness is unsatisfactory.
Two above patent all can not be completely secured safety.
Summary of the invention
For solving disadvantages described above; it is an object of the invention to provide a kind of rational in infrastructure, implementation is simple; in the case of battery temperature exception and outside heat, physical impact, lithium ion battery can be provided safeguard protection, and have the Li-ion batteries piles of the high security of fire extinguishing and cooling double shield concurrently.
The technical solution adopted for the present invention to solve the technical problems is: a kind of high security lithium ion battery, including the sealed cell case being made up of casing and case lid and the some Li-ion batteries piles being arranged in battery case, liquified Halon extinguishing chemical is filled in described battery case, described liquified Halon extinguishing chemical is Triodie, FC308, FC410, FC614, NAFS-III, PE-241, PE-25, FM-200, PE-13, the mixture of one or more in PE-36, described Li-ion batteries piles is made up of more than one lithium-ion battery monomer, it is provided with on described battery case and fills mouth, one or more relief valve it is provided with on described case lid.
Described a kind of high security lithium ion battery, is additionally provided with liquidometer outside its battery case, liquid level is battery case inner height 1/4~the 3/4 of described liquified Halon extinguishing chemical.
Described a kind of high security lithium ion battery, its battery case can bear the pressure of 1.5~3.0MP.
Described a kind of high security lithium ion battery, in the range of the cracking pressure of its relief valve is arranged on 0.7~3.0MP, in the range of valve closing pressure is arranged on 0.3~1.6MP.
The invention has the beneficial effects as follows: the high security battery case of the present invention, cope with the various safe condition being likely to occur: either occur by abusing, short circuit, outside heat impacts the Li-ion batteries piles internal temperature abnormal conditions caused, or caused lithium ion battery or the situation of battery case breakage deformation by external physical impact, battery case interior liquid halon extinguishing agent rapid evaporation will be caused, reduce rapidly battery pack temperature, and inside and outside battery case, form low temperature inerting air insulated band or put out the outside burning things which may cause a fire disaster of battery case, thus reach to stop Li-ion batteries piles that possibility the most out of control occurs;Meanwhile, according to set of cells characteristic as above, each high security set of cells can act as small-sized fighting terminal, it is possible to dynamical system or other neighbouring equipment for Li-ion batteries piles place provide Partial security protection to a certain extent.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Each reference is: 1 casing, 2 liquified Halon extinguishing chemicals, 3 Li-ion batteries piles, 11 case lids, 12 relief valves, and 13 fill mouth, 14 liquidometers, 31 lithium-ion battery monomers.
Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention is described in further detail.
With reference to shown in Fig. 1, the invention discloses a kind of high security lithium ion battery, including some Li-ion batteries piles 3 and the sealed cell case of receiving battery, Li-ion batteries piles 3 is made up of more than one lithium-ion battery monomer 31, battery case is made up of casing 1 and case lid 11, filling insulation and liquescent halon extinguishing agent in described battery case, liquified Halon extinguishing chemical 2 is filled in the space between lithium-ion battery monomer 31.
When set of cells causes battery pack temperature exception because of the internal factors such as abuse, short circuit or outside heat impact, the steam of evaporation can be derived by relief valve 12, take away the heat that set of cells is unnecessary, and inside and outside battery case, form one layer of gas extinguishing agent isolation strip, and inerting ambient air, suppression Li-ion batteries piles 3 is the most out of control or puts out the outside burning things which may cause a fire disaster of set of cells.
If battery case is by external physical impact, cause battery case damaged, battery case air pressure inside reduces, halon extinguishing agent evaporates rapidly, reduce battery pack temperature and also form low temperature inerting air insulated band in battery case inside and around, the situation generations such as the even fire out of control that lithium ion battery blastic deformation occurs can be suppressed.
Alkyl halide in battery case is the gas extinguishing agent of liquefaction, so battery case must be hermetic, and can bear the pressure of at least 1.5~3.0MP;These several halon extinguishing agent non-corrosivenesss, therefore, the material of battery case shell does not has the restriction that corrosion resistance requires, only with the pressure requirements ensureing battery case.
