Description
Technical field
This utility model relates to lithium ion battery production technical field, is specifically related to a kind of modern high security lithium-ion electric
Pond.
Background technology
Lithium ion battery is a kind of New Green Energy source battery, and it has higher discharge platform, high-energy-density, use longevity
Order the advantages such as longer and memory-less effect, based on its advantage lithium ion battery be widely used electric automobile, unmanned plane and
The important industry such as mobile device, but due to short circuit and the existence of side reaction, there is the hidden dangers such as on fire, the blast of generation, sternly
Ghost image rings the application of lithium ion battery.The direction high to specific energy density is developed by following lithium ion battery, its safety issue
The most important thing especially, needs enough concerns and attention.
At present for the method improving lithium ion battery security, prepare except finding the substitution material such as solid electrolyte
Outside battery, optimizing battery structure is also effective method.Through development for many years, current most of business-like lithium ion
Battery design mainly carrys out the pressure within buffer battery explosion time by increase explosion-proof valve, but also cannot thoroughly solve the peaces such as blast
Full problem.
Utility model content
The purpose of this utility model is for the deficiencies in the prior art, existing offer a kind of structure letter
Single, the modern high security lithium ion battery that security performance is high.
For solving above-mentioned technical problem, the technical solution adopted in the utility model is: a kind of modern high security lithium ion
Battery, its innovative point is: be followed successively by lithium ion battery cell, explosion-proof net and battery case, described lithium-ion electric from inside to outside
Pond battery core, explosion-proof net and battery case are fixedly connected successively, and described explosion-proof net is poly P phenylene diamine terephthalamide polymer.
The beneficial effects of the utility model are as follows:
(1) this utility model with the addition of the explosion-proof net of poly P phenylene diamine terephthalamide polymerizable material, paraphenylene terephthalamide couple
Phenylenediamine polymer be a kind of intensity be 5～6 times of steel wire, modulus is 2～3 times of steel wire, and toughness is 2 times of steel wire, 560
Do not decompose at a temperature of DEG C, do not melt, there is the material of good insulating properties and ageing resistace, be very suitable for applying at battery
In；In the case of battery explosion less due to inner space, may result in metal battery case and burst and hurt people,
When, after adding explosion-proof net, when pond air pressure inside is higher, explosion-proof net has the character of high intensity, high-modulus, can play buffering
Effect, prevents battery case from bursting to a certain extent, thus improves security performance.
(2) weight of the explosion-proof net that this utility model adds is only about the 1/5 of steel wire, at suitable reduction lithium-ion electric
While the outer casing thickness of pond, increasing by one layer of explosion-proof net, it is possible to the effective weight lowering lithium ion battery, buffer battery is outside right
The impact that battery core causes, can also reduce the injury that lithium ion battery produces at explosion time simultaneously, is effectively protected battery and makes
User.
Accompanying drawing explanation
Fig. 1 is sectional view of the present utility model.
Detailed description of the invention
By particular specific embodiment, embodiment of the present utility model being described below, those skilled in the art can be by this
Content disclosed by description understands other advantages of the present utility model and effect easily.
It is illustrated in figure 1 sectional view of the present utility model, a kind of modern high security lithium ion battery, the most successively
For lithium ion battery cell 3, explosion-proof net 2 and battery case 1, lithium ion battery cell 3, explosion-proof net 2 and battery case 1 enter successively
Row is fixing to be connected.
Explosion-proof net 2 is poly P phenylene diamine terephthalamide polymer, and this utility model with the addition of poly P phenylene diamine terephthalamide
The explosion-proof net 2 of polymerizable material, poly P phenylene diamine terephthalamide polymer be a kind of intensity be 5～6 times of steel wire, modulus is steel
2～3 times of silk, toughness is 2 times of steel wire, does not decomposes, do not melts at a temperature of 560 DEG C, has good insulating properties and resists
The material of ageing properties, is very suitable for applying in the battery；In the case of battery explosion less due to inner space, may
Metal battery case 1 can be caused to burst and to hurt people, when after adding explosion-proof net 2, when pond air pressure inside is higher, explosion-proof net
2 character with high intensity, high-modulus, can play cushioning effect, prevent battery case 1 from bursting to a certain extent, thus carry
High security performance.
Production method: be first wound by lithium battery electric core 3, loads in explosion-proof net 2 by battery core 3 after having wound, anti-
Lithium ion battery cell 3 and explosion-proof net 2, without any restriction, are put into battery case 1 by the shape of quick-fried net 2 and quality the most again,
Other operations are completed according to normal operating technique,.
The weight of the explosion-proof net 2 that this utility model adds is only about the 1/5 of steel wire, at suitable reduction lithium ion battery
While shell 1 thickness, increasing by one layer of explosion-proof net 2, it is possible to the effective weight lowering lithium ion battery, buffer battery is outside right
The impact that battery core 3 causes, can also reduce the injury that lithium ion battery produces at explosion time simultaneously, is effectively protected battery and makes
User.
Above-described embodiment is preferred embodiment of the present utility model, is not the limit to technical solutions of the utility model
System, as long as the technical scheme that can realize on the basis of above-described embodiment without creative work, is regarded as falling into
In the range of the rights protection of this utility model patent.
