Polymer dielectric, by using the electron transport ability of Graphene, can be provided simultaneously with conventional batteries and lithium ion battery
Advantage, is particularly suitable as lithium battery and uses.Preferably, described gelatin polymer also includes additive, and additive is all coagulating
The mass ratio of xanthan polymer is 0.5% to 3%.For example, described additive includes organic solvent, and for example, described additive includes
Maleimide or derivatives thereof.Preferably, described additive also includes esters, such as ethyl acetate, ethyl propionate, propylene glycol
Carbonic ester etc..
There may be the extent of injury of explosion danger to reduce lithium battery continuous high temperature, for example, described housing described
Wall portion wears some through holes;So, when blast occurring or burning, gases at high pressure can release part from through hole, it is to avoid sudden and violent
Send out excessively acutely such that it is able to the power of releive blast or burning.In order to keep the closed environment of battery core it is preferred that each institute
State setting thin film on through hole so that described enclosure interior forms sealed environment or near-hermetic environment;So, explode
When, the physical strength of thin film is less than the physical strength of wall portion, and thin film splits in advance, and gases at high pressure first can release portion from through hole
Point, the threat for housing or wall portion is just smaller, or even can also protect wall portion.For example, described housing has top, wall portion
With bottom, for the ease of producing, the inner surface setting thin film of described wall portion, the inner surface of described wall portion be described wall portion to
The one side of described cavity, that is, the wall portion of described housing is convexly equipped with the one side of some bodies to described cavity;For example, described thin film
For plastic sheeting;Preferably, described thin film is single permeable membrane, and described single permeable membrane has from described enclosure interior to described hull outside
Unidirectional permeability, the gas molecules of wherein said enclosure interior can escape to described hull outside from described enclosure interior
Dissipate;This way it is possible to avoid because the bulge accident of the excessive generation of internal pressure is moreover it is possible to first pass through institute before there is explosion danger
State single permeable membrane and dissipate out portion gas, when there is explosion danger, described thin film or described single permeable membrane split in advance, gases at high pressure
First part being released from through hole, thus reducing brisance, certain protection can be provided to user.Preferably, use
The some scattered gas passages of the product of described lithium battery also matching design, can reach more preferable safe effect.
Preferably, the aperture of described through hole is less than 100 nanometers;For example, the aperture of described through hole is less than 50 nanometers;Preferably
, the aperture of described through hole is less than 10 nanometers.Preferably, described housing includes shell and inner shell, and described shell arranges some institutes
State through hole.Preferably, the physical strength of described inner shell is less than the physical strength of described shell;So, when causing danger, inner shell
First debacle, absorbs part energy, then by each described through hole pressure release of described shell, can provide certain guarantor to user
Shield.Preferably, described inner shell have mesh-structured, described mesh-structured aperture be more than described through hole aperture.For example, described
Mesh-structured area exceedes 2 times of the area of described through hole.Preferably, described mesh-structured area exceedes described through hole
7 times of area.And for example, the intensity of described inner shell is more than the intensity of described shell.For example, there is the intensity of mesh-structured inner shell
More than the intensity of described shell, as such, it is possible to carry out multilamellar pressure release by mesh-structured with through hole.Preferably, described mesh knot
Structure setting straggly with described through hole, that is, described mesh-structured and described through hole is non-is oppositely arranged, in other words, described mesh-structured
Extend parallel with the extension of described through hole and completely misaligned, so, explosion gas can not directly run through described mesh-structured and
Described through hole, needs slightly to disperse between described inner shell and described shell or bending is such that it is able to reduce to a certain extent
Brisance.Preferably, it is additionally provided with flame-retardant layer, such as aluminum based flame retardant such as three oxidation two between described inner shell and described shell
Aluminum, or organic phosphates fire retardant etc.;And for example, described flame-retardant layer is coating, and for example, described flame-retardant layer is flame retardant coating, for example,
Described flame retardant coating apply located at described inner shell towards described shell or described shell towards described inner shell while;Again
As described inner shell is chitin fiber layer, and it is coated with described flame retardant coating towards the one side of described shell.So, have preferably
Anti-riot flame retardant effect.
Further, embodiments of the invention also include, each technical characteristic of the various embodiments described above, are mutually combined formation
Lithium battery.
It should be noted that above-mentioned each technical characteristic continues to be mutually combined, form the various embodiments not being enumerated above,
It is accordingly to be regarded as the scope of description of the invention record;And, for those of ordinary skills, can add according to the above description
To improve or to convert, and all these modifications and variations all should belong to the protection domain of claims of the present invention.
