Abstract
This utility model provides a kind of shockproof effect good lithium-ion electric core, including the core formed by positive plate, negative plate and membrane winding and the aluminum plastic film being coated on the outside of core, shakeproof layer is additionally provided between the core and aluminum plastic film, the shakeproof layer passes through hot pressing mode inner side bonding connection respectively with core and aluminum plastic film.Shakeproof layer is provided between core of the present utility model and aluminum plastic film, so, just there is no gap between core and aluminum plastic film, during transport or use, core would not be also collided or be rubbed with aluminum plastic film inwall, more will not make the aluminium lamination of aluminum plastic film directly and electrolyte contacts because the pp layers of aluminum plastic film sustain damage, so as to improve the security performance of lithium battery；, by hot pressing mode inner side bonding connection respectively with core and aluminum plastic film, so the connection between core, shakeproof layer and aluminum plastic film is even closer for the shakeproof layer, further realizes shockproof effect, improves the security performance of lithium battery.
Description
Technical field
This utility model is related to lithium-ion electric core production technical field, the good lithium-ion electric of more particularly to a kind of shockproof effect
Core.
Background technology
The external package casing of lithium ion battery, it is different according to profile, including cylindrical, square.It is divided into according to packaging material
The outsourcing of aluminum housing, ferrous casings, aluminum-plastic packaged housing, high molecule plastic resin-case and other compound use above-mentioned materials
Dress housing.Aluminum housing is logical to be referred to using fine aluminium and housing made by aluminum alloy materials, and ferrous casings are logical to be referred to using ferrum and ferroalloy
Housing made by material.The effect of the housing material of lithium ion battery is to provide the confined air of a receiving cell active materials
Between, while providing certain mechanical strength and mechanical protection.As application is for the bulking value density and appearance of lithium ion battery
The requirement more and more higher of amount bulk density, increasing lithium ion battery adopt aluminum-plastic packaged housing.
It is usually by positive plate, negative plate and membrane winding rolling using the structure of the lithium ion battery of laminated aluminum film
It is inserted in aluminum plastic film again after core.But aluminum plastic film mechanical strength is not so good as box hat or aluminum hull after all, aluminum plastic film being collided or
It is easily damaged or pierced after person's friction.After battery core encapsulation, due to there are space between core and aluminum plastic film, and
During transport or use, battery core can be given a shock unavoidably, and thus core can be collided with aluminum plastic film inwall unavoidably
Or friction, so, the PP layers of aluminum plastic film inwall are just highly susceptible to damage, and the aluminium lamination in such aluminum plastic film is exposed to electrolysis
In liquid, so as to cause lithium battery expansion and failure, the security incident such as can also set off an explosion when serious.
Utility model content
Disappearance of this utility model for prior art presence, there is provided a kind of good lithium-ion electric core of shockproof effect, its energy
It is effectively prevented from during transport or use because the core in lithium-ion electric core is collided or rubbed with aluminum plastic film inwall
Wipe and cause the pp layers of aluminum plastic film to sustain damage, it is to avoid the aluminium lamination in aluminum plastic film directly and electrolyte contacts, so as to improve lithium
The security performance of battery.
For achieving the above object, this utility model is using such as purgation technical scheme：
A kind of good lithium-ion electric core of shockproof effect, including the core formed by positive plate, negative plate and membrane winding and
The aluminum plastic film being coated on the outside of core, is additionally provided with shakeproof layer between the core and aluminum plastic film, the shakeproof layer passes through hot pressing side
Formula inner side bonding connection respectively with core and aluminum plastic film.
Used as a kind of preferred version, the shakeproof layer is in the netted outside for being coated on core.
Used as a kind of preferred version, the shakeproof layer is the coextruded layer formed by CPP and MODIFIED PP A.
This utility model compared with prior art, with advantages below and advantage, specifically, the core and aluminum plastic film
Between be provided with shakeproof layer, so, between core and aluminum plastic film, just there is no gap, during transport or use roll up
Core would not be also collided or be rubbed with aluminum plastic film inwall, more will not make aluminum plastic film because the pp layers of aluminum plastic film sustain damage
Aluminium lamination directly and electrolyte contacts, so as to improve the security performance of lithium battery；The shakeproof layer by hot pressing mode respectively with volume
The inner side bonding connection of core and aluminum plastic film, so the connection between core, shakeproof layer and aluminum plastic film is even closer, further
Shockproof effect is realized, the security performance of lithium battery is improved.
More clearly to illustrate architectural feature of the present utility model, technological means and its specific purposes for being reached and work(
Can, below in conjunction with the accompanying drawings with specific embodiment being described in further detail to this utility model：
Description of the drawings
Fig. 1 is the assembly structure diagram of the embodiment of this utility model；
Fig. 2 is the assembling assumption diagram of the core with shakeproof layer of this utility model；
Fig. 3 is the structural representation of the shakeproof layer of this utility model.
Accompanying drawing identifier declaration：
1- core, 2- aluminum plastic films, 3- shakeproof layers, 31-CPP, 32-PPA
Specific embodiment
As Figure 1-3, the good lithium-ion electric core of a kind of shockproof effect, including by positive plate, negative plate and membrane winding
The core 1 and the aluminum plastic film 2 being coated on the outside of core 1 of formation, is additionally provided with shakeproof layer 3, institute between the core 1 and aluminum plastic film 2
Shakeproof layer 3 is stated by hot pressing mode inner side bonding connection respectively with core 1 and aluminum plastic film 2.The shakeproof layer 3 is in netted cladding
In the outside of core 1.The shakeproof layer 1 is the coextruded layer formed by CPP31 and MODIFIED PP A32 co-extrusion.
The above, is only preferred embodiment of the present utility model, not to limit this utility model, thus it is every
Any modification, equivalent substitution and improvements actually made to above example according to technology of the present utility model etc., still fall within this
In the range of utility model technical scheme.
