Description
Technical field
The present invention relates to a kind of lithium battery, specifically a kind of lithium battery explosion-proof flame-retardant structure.
Background technology
Lithium battery, be it is a kind of by lithium metal or lithium alloy be negative material, the battery using non-aqueous electrolytic solution.With
The fast development of the industries such as mobile phone, notebook computer, digital camera, electric car, electric tool, new-energy automobile, to lithium battery
Demand will constantly increase, simultaneously as the innovation of lithium battery manufacturer technically, people to the demand of lithium battery still
Can constantly it increase.Lithium battery has the advantages such as energy comparison is high, service life is long, light self-discharge rate is low.In order to reduce the external world
The influence of environment, lithium battery group would generally be placed in relatively closed environment.These use conditions can cause lithium battery group to exist
Caused substantial amounts of heat smoothly and can not be discharged quickly in the course of work, cause lithium battery temperature to steeply rise, long-time work
Make at a higher temperature, battery will to be shortened, reduce battery performance;Permanent uneven point of temperature field in battery case
Cloth by cause each lithium battery module, monomer performance it is unbalanced, and then influence the performance of whole battery system.Lithium battery is present
Security is poor, there is the danger exploded, and high/low temperature uses dangerous big.
The content of the invention
A kind of the shortcomings that the invention aims to overcome prior art to exist, there is provided simple in construction, easy to use, energy
A kind of lithium battery explosion-proof flame-retardant structure that enough phenomena such as effectively preventing lithium battery from combustion explosion occurs using process occur.
The present invention seeks to what is realized with the following methods：A kind of lithium battery explosion-proof flame-retardant structure, it includes shell, mask,
Enclosure is provided with accommodating cavity, and some lithium battery packs, lithium battery pack and the electrode being arranged on mask are provided with accommodating cavity
Connection, it is characterised in that：Fire extinguishing layer is provided between described accommodating cavity and lithium battery pack, fire extinguishing layer includes low melting point isolation pocket
And set liquid fire retardant in the inner.
Described low melting point isolation pocket is arranged to interior empty rectangular-shaped, and lithium battery pack is placed on the inside of isolation pocket.
Described fire extinguishing layer is arranged on the side wall of accommodating cavity.
Described fire extinguishing layer is arranged on the inside of mask, between mask and lithium battery pack.
Described fire extinguishing layer is arranged between adjacent two lithium battery pack.
Described low melting point isolation pocket is fabricated by low melting point polymer.
Described liquid fire retardant is pure water.
Described liquid fire retardant is fire foam.
The beneficial effects of the invention are as follows：1st, simple in construction, production cost is low, improves the market competitiveness.2nd, low melting point is utilized
Extinguishing chemical built in isolation pocket coats lithium battery, when burn occurs in lithium battery, high temperature melt isolation pocket so that in isolation pocket
Fire retardant can play a part of cooling and dilute electrolyte, prevent that lithium battery catching fire from the accident hair such as even exploding
Security raw, that lifting battery uses.3rd, for the battery of different parameters, the position position of fire extinguishing layer, quantity can accordingly be adjusted
Deng adaptation different places use to greatest extent.
Brief description of the drawings
Fig. 1 is structure sectional view of the present invention.
Fig. 2 is the partial structurtes enlarged drawing of Fig. 1 in the present invention.
Fig. 3 is the second embodiment schematic diagram of fire extinguishing layer in the present invention.
Embodiment
Make specific further instruction to the present invention below in conjunction with the accompanying drawings.A kind of lithium battery explosion-proof flame-retardant structure, it includes
Shell 1, mask 2, shell 1 are internally provided with accommodating cavity 3, some lithium battery packs 4 are provided with accommodating cavity 3, lithium battery pack 4 is with setting
Put the electrode connection on mask 2, it is characterised in that：Fire extinguishing layer 5 is provided between described accommodating cavity 3 and lithium battery pack 4, is gone out
Fire bed 5 includes low melting point isolation pocket 51 and sets liquid fire retardant 52 in the inner.
Described low melting point isolation pocket 51 is arranged to interior empty rectangular-shaped, and lithium battery pack 4 is placed on the inside of isolation pocket.
Described fire extinguishing layer 5 is arranged on the side wall of accommodating cavity.
Described fire extinguishing layer 5 is arranged on the inside of mask 2, between mask 2 and lithium battery pack 4.
Described fire extinguishing layer 5 is arranged between adjacent two lithium battery pack 4.
Described low melting point isolation pocket 51 is fabricated by low melting point polymer.
Described liquid fire retardant 52 is pure water.
Described liquid fire retardant 52 is fire foam.
Operation principle：In this case, liquid fire retardant has been poured into layer of putting out a fire, and layer of putting out a fire is fabricated to multiple styles, will
Lithium battery pack 4 is coated in it, when lithium battery breaks down, can produce high temperature, and high temperature melts the isolation pocket 51 of low melting point,
The liquid fire retardant 52 in it is caused to leak, the liquid fire retardant 52 of leakage covers to burning-point, plays cooling fire extinguishing
And the effect of dilute electrolyte, prevent chemical reaction from continuing to produce, so as to avoid lithium battery because continuing high temperature so as to cause lithium
Battery catches fire even explodes, so as to improve the security of lithium battery.
Wherein, as shown in Figure 1, 2, the fire extinguishing layer in this case can be set between shell 1 and adjacent two lithium battery pack, to every
Battery pack can play protective action, be adapted to high temperature, the severe battery for waiting environment to use.As shown in figure 3, and for some uses
Environment is relatively good, the place of temperature stabilization, then fire extinguishing layer can be only set between lithium battery pack inside the housing, so as to reduce
Production cost and battery volume, therefore, used for different places, select different models, so as to lift being applicable for this battery
