Abstract
The invention discloses an explosion-proof lithium-ion battery. The explosion-proof lithium-ion battery comprises a battery body, the surface of the battery body is wraped with a film, and the film shows heat dissipation property and flame retardance when the battery body is in thermal runaway. The film is prepared from, by weight, 100-500 parts of bismuth triamine, 2-10 parts of graphene oxide, 20-30 parts of diethylenetriamine, 40-60 parts of polyamide resin, 10-20 parts of fluorinated polyolefin resin and 50-100 parts of polyamide curing agent. The explosion-proof lithium-ion battery solves the problem that the combustion explosion may occur after the lithium ion temperature is out of control. The graphene oxide film on the surface of the battery body has both insulation property and heat conduction property, and the use safety of the battery is thus effectively guaranteed.
Description
Technical field
The present invention relates to a kind of anti-explosion lithium ion battery.
Background technology
Lithium ion battery has that energy density is big, power output is high, discharge and recharge life-span length, pollution-free, operating temperature range
Many advantages, such as width and self discharge are little.It, as new high-energy chemistry power supply, is polluting and the energy towards solution human environment
During crisis is advanced, encounter challenge the hugest, i.e. safety problem.Lithium ion battery can be because of overcurrent, internal branch
Crystalline substance leads to internal short-circuit or the abuse conditions such as overcharges, and leads to the heat accumulation of inside, when thermal accumlation to a certain extent when, meeting
Cause electrolyte, positive pole and internal other materials that heat release chain reaction occurs, ultimately result in lithium battery and thermal runaway occurs.
Solve the problems, such as that the approach of lithium ion battery security mainly includes two aspects at present.On the one hand it is by using safeguarding
Or Added Management is ensureing its security.As prevented lithium ion battery short circuit, overcharging and super by lithium ion battery management system
Temperature etc..On the other hand it is then the security improving lithium ion battery itself by improving lithium battery material or optimization design.As
By improving positive electrode stability, add the additive such as fire-retardant and anti-overcharge in the electrolytic solution, using new types of diaphragm (as made pottery
Porcelain barrier film) etc. mode.But said method, because of the restriction of various factors, all cannot fundamentally solve lithium ion battery at present
Safety issue.
Content of the invention
It is an object of the invention to a kind of anti-explosion lithium ion battery is it is intended to solve the above problems.
To achieve these goals, the technical scheme is that a kind of anti-explosion lithium ion battery of design, including battery originally
Body, described battery body Surface coating film, described film radiates from being used for when battery body occurs thermal runaway fire-retardant work
With；Described film composition is respectively by weight：Brominated eopxy resin：100 ~ 500 parts, graphene oxide：2 ~ 10 parts, divinyl three
Amine：20 ~ 30 parts, 40 ~ 60 parts of polyamide, 10 ~ 20 parts of fluorinated polyolefin resin, 50 ~ 100 parts of polyamide curing agent.
Advantages of the present invention and having the beneficial effects that：This anti-explosion lithium ion battery may after solving lithium ion temperature control
There is the situation of combustion explosion.The graphene oxide film on battery body surface has the double attribute of insulation and heat conduction, effectively
Ensure the safe handling of battery.
