Abstract
The invention discloses a kind of lithium ion battery insulating heat-conductive film, the insulating heat-conductive film is used to coat battery body surface, and the insulating heat-conductive film is composed of the following components：Polysiloxane polyether copolymer, oxidation of alkyl amine APEO, dipotassium tetraborate, lauryl sodium sulfate, Negel, sodium pyrophosphate, anhydride maleique, carborundum, methyl laurate, methyl methacrylate.Insulating heat-conductive film of the present invention has the double attribute of insulation and heat conduction, the insulating heat-conductive film coated battery body surface, can effectively improve the security performance of battery.
Description
Technical field
The present invention relates to a kind of lithium ion battery insulating heat-conductive film.
Background technology
Lithium ion battery has that energy density is big, power output is high, discharge and recharge long lifespan, pollution-free, operating temperature range
Many advantages, such as wide and self discharge is small.It is as new high-energy chemistry power supply, towards solving human environment pollution and the energy
During crisis is advanced, challenge the hugest, i.e. safety problem are encountered.Lithium ion battery can be because of overcurrent, internal branch
Crystalline substance causes internal short-circuit or the abuse conditions such as overcharges, and causes the heat accumulation of inside, when thermal accumlation to a certain extent when, meeting
Trigger electrolyte, positive pole and internal other materials that heat release chain reaction occurs, ultimately result in lithium battery and thermal runaway occurs.
The approach for solving the problems, such as lithium ion battery security at present mainly includes two aspects.On the one hand it is by using maintenance
Or Added Management ensures its security.Lithium ion battery short circuit is such as prevented by lithium ion battery management system, overcharges and surpasses
Temperature etc..On the other hand it is then to improve the security of lithium ion battery itself by improving lithium battery material or optimization design.Such as
By improving positive electrode stability, the additive such as fire-retardant and anti-overcharge is added in the electrolytic solution, using new types of diaphragm（Such as ceramics
Barrier film）Etc. mode.But the above method can not fundamentally solve the peace of lithium ion battery at present because of the limitation of various factors
Full sex chromosome mosaicism.
The content of the invention
It is an object of the invention to provide a kind of lithium ion battery insulating heat-conductive film, the insulating heat-conductive film has exhausted
Edge and the double attribute of heat conduction, the insulating heat-conductive film coated battery body surface, the security performance of battery can be effectively improved.
To achieve the above object, should the technical scheme is that designing a kind of lithium ion battery insulating heat-conductive film
Insulating heat-conductive film is used to coat battery body surface, and the insulating heat-conductive film is composed of the following components：Silicone polyether is total to
Polymers, oxidation of alkyl amine APEO, dipotassium tetraborate, lauryl sodium sulfate, Negel, sodium pyrophosphate, butylene
Dicarboxylic anhydride, carborundum, methyl laurate, methyl methacrylate.
Preferably, insulating heat-conductive film by weight is composed of the following components：
4.2 parts of polysiloxane polyether copolymers,
3.1 parts of oxidation of alkyl amine APEOs,
1.2 parts of dipotassium tetraborates,
2.5 parts of lauryl sodium sulfate,
