Description
Technical field
The present invention is filled in the interstitial functional material of battery pack, and in particular to a kind of lithium electricity filler.
Background technology
With power lithium battery（Power-type lithium ion battery or Li-ion batteries piles）It is the most critical part on electric automobile, can
It is the emphasis of electric automobile research to be referred to as the heart of electric automobile.
The high power and fast charging and discharging of power lithium battery are the trends of the times of Development of Electric Vehicles.For battery pack,
Charge-discharge magnification is higher, and its heating is also faster, and temperature has double influence to battery：Temperature is higher, and the internal resistance of cell is got over
Small, corresponding battery efficiency is also higher；At the same time, the various chemical reactions that high temperature can be in acceleration system, especially may
Battery structure is set to produce the speed of the adverse reaction of permanent lesion.Furthermore during non-uniform temperature, it is partially under hot conditions
Battery pole piece be also easily damaged, easily cause over-charging of battery, have a strong impact on battery（Group）Performance extremely service life, shows as
The electricity that can be filled with is fewer and fewer, and heating is also more serious, when heat effectively cannot be transmitted or distributed, easily causes battery
The chemical property of group declines and the generation of single battery backwardness phenomenon, and the soft drum of battery, on fire, blast etc. can be also caused when serious
Security incident.
At present in terms of system radiating, caused heat row when taking the devices such as installation fan that system works mostly
Go out, and the trend of internal system air stream requires tighter to fan mounting means, furthermore the power of fan and its exhaust air rate etc.,
It can be limited by the structure of system and its internal module.
The content of the invention
In view of the shortcomings of the prior art, the invention provides a kind of lithium electricity filler, in the process of lithium electricity, by it
It is filled into the battery pack space of lithium electricity, effectively lithium battery can be radiated, technique is simple, it is not necessary to peripheral hardware radiating dress
Put；And by increasing fire retardant, battery pack caused heat in use can be absorbed, while connect when battery temperature is too high
During near or fuel value more than paraffin, flame retardant effect can be played, eliminates the potential safety hazards such as lithium electrical fire, blast；Pass through increase
Refrigerant carries out refrigeration radiating from internal battery pack, further improves the heat-sinking capability of lithium electricity, reduces the operating temperature of lithium battery,
And cause the temperature difference of battery pack temperature uniformly, in elimination battery pack between each battery, effectively prevent that battery pack is uneven because of radiating
Cause the soft bulging accident of the too high caused battery of local temperature；The present invention can effectively improve the safety of lithium electricity in use
Property, improve the electric service life of lithium.
It is an object of the invention to provide a kind of lithium electricity filler, for being filled into the battery pack space of lithium electricity, comprising
Paraffin, fire retardant, refrigerant, the mass ratio of each component are：Paraffin 25%~90%, fire retardant 5%~70%, refrigerant 3%~
20%。
Further improvement of the present invention is：The refrigerant is calcium bromide.
Further improvement of the present invention is：The fire retardant is selected from least one of following material：（1）Zinc fluoride,（2）
Molybdenum system compound,（3）The mixture of antimony oxide or antimony oxide and halide,（4）Halide,（5）Phosphate or phosphate
Salt,（6）Borate,（7）Magnesia or aluminum oxide.
Further improvement of the present invention is：In the mixture of the antimony oxide or antimony oxide and halide halogen and
The molar ratio of antimony is >=3：1.
Further improvement of the present invention is：The molar ratio of halogen and antimony is >=3 in the fire retardant：1.
Further improvement of the present invention is：The molybdenum system compound is selected from molybdenum oxide or molybdenum sulfide.
Further improvement of the present invention is：The halide is selected from chain fatty race, annular aliphatic or aromatic series halogen
Compound.
Further improvement of the present invention is：The halide is selected from annular aliphatic chloride or decabromodiphenyl aoxidizes
Thing.
Further improvement of the present invention is：The paraffin, fire retardant and refrigerant are solid state or liquid condition.
The beneficial effects of the invention are as follows：In the process of lithium electricity, filler is filled into battery pack space, energy
Enough that effectively lithium battery is radiated, technique is simple, it is not necessary to peripheral hardware heat abstractor；And by increasing fire retardant, it can inhale
Receive battery pack caused heat in use, while when the too high fuel value near or above paraffin of battery temperature, energy
Flame retardant effect is enough played, eliminates the potential safety hazards such as lithium electrical fire, blast；Freezed by increasing refrigerant from internal battery pack
Radiate, further improve the heat-sinking capability of lithium electricity, reduce the operating temperature of lithium battery, and make it that battery pack temperature is uniform, eliminates
Temperature difference in battery pack between each battery, effectively prevent battery pack battery caused by radiating inequality causes local temperature too high
Soft bulging accident；The present invention can effectively improve the security of lithium electricity in use, improve the service life of lithium electricity.
