Description
Technical field
The utility model relates to field of batteries, and in particular to a kind of chargeable button-shaped soft bag lithium ionic cell.
Background technique
Existing button battery, including alkali manganese of 1.5V, zinc-manganese and 3V lithium primary cell, 3.6V lithium-ion battery with steel shell.
Traditional button-type lithium cell battery is metal material, can be on fire from explosion, and safety is poor, and than heavier, is not suitable for bluetooth
The field relatively high to weight, security requirement such as earphone.Traditional button lithium battery production efficiency is low.
18650 volumes are big, weight weight, are rigid shell structure, mechanical encapsulation, using relief valve as over-voltage release channel.
Chargeable lithium coin cells in the market are all metal shell, mechanical encapsulation simultaneously.Core be usually it is stacked or
Bag is filled a vacancy formula, and technique is cumbersome, cannot automate.It is widely used in soft bag lithium ionic cell all sides of being of the digital products such as mobile phone
Shape structure, positive and negative anodes collector ipsilateral extraction directly inside core, is not suitable for making button soft bag lithium ionic cell.
And traditional soft packet cylindrical battery needs two aluminum plastic film air bags, encapsulates twice, has lead angle to need bending just after encapsulation
It can be used with electronic product matching, production efficiency is lower, and bending risk is big, and battery is easily damaged.
Utility model content
In view of the above-mentioned problems, the utility model be intended to provide one kind have a safety feature, light quality, production efficiency it is higher
Chargeable button-shaped soft bag lithium ionic cell.
To realize that the technical purpose, the embodiment of the utility model be: a kind of chargeable button-shaped soft bag lithium ionic cell,
Be characterized in that: including shell, the shell is cylindrical plastic-aluminum combined membrane structure, be provided in the shell anode pole piece,
Diaphragm and cathode pole piece, the diaphragm is between anode pole piece and cathode pole piece, the anode pole piece, diaphragm and cathode pole piece
Column core structure is rolled into be placed in shell；
Electrolyte is also filled between the anode pole piece and cathode pole piece；
The anode pole piece is also electrically connected to positive pole ear, and the cathode pole piece is also electrically connected to negative lug.
The beneficial effects of the utility model, the application is using plastic-aluminum structure as shell, and processing is more convenient, while quality
Lighter, installation effectiveness is high, and security seal performance is good；It is rolled into column core structure using by anode pole piece, diaphragm and cathode pole piece,
It produces and processes more efficient；The anode and cathode of the application is drawn convenient to use from two sides；The application uses a plastic-aluminum putamina
Body, it is primary to encapsulate, it is not necessarily to bending without lead angle after encapsulation, production efficiency is lower, safety and stability.
Detailed description of the invention
Fig. 1 is the structural schematic diagram in the vertical view face of the utility model；
Fig. 2 is the structural schematic diagram in the right view face of the utility model；
Fig. 3 is the structural schematic diagram of the utility model.
Specific embodiment
The utility model is described in further details in the following with reference to the drawings and specific embodiments.
As shown in Figure 1-3, specific embodiment described in the utility model is a kind of chargeable button-shaped Soft Roll lithium-ion electric
Pool structure, including shell 1, the shell 1 are cylindrical plastic-aluminum combined membrane structure, are provided with anode pole piece in the shell 1
2, diaphragm 3 and cathode pole piece 4, the diaphragm 3 is between anode pole piece 2 and cathode pole piece 4, the anode pole piece 2, diaphragm 3
Column core structure is rolled into cathode pole piece 4 to be placed in shell 1；
Electrolyte is also filled between the anode pole piece 2 and cathode pole piece 4；
The anode pole piece 2 is also electrically connected to positive pole ear 5, and the cathode pole piece 4 is also electrically connected to negative lug 6.This
The positive and negative tab of application leans out positive and negative tab opposition reversely in core tail portion, different from conventional batteries.
Specific procedure of processing is as follows:
The first step forms, and under room temperature, is stamped and formed out concave shell on aluminum-plastic composite membrane by mold；
Second step, assembling, is put into shell after anode pole piece, diaphragm and cathode pole piece are rolled into column core structure,
Then septation injects electrolyte between injection anode pole piece and cathode pole piece between anode pole piece and cathode pole piece；
Third step, installation, by positive pole ear ultrasonic bonding on anode pole piece, by negative lug electric resistance welding negative
On the pole piece of pole；
4th step, encapsulation, the shell that group installs is sealed by thermoplastic package technique, encapsulates condition: temperature 180-
It 190 DEG C, pressure 0.25-0.4Mpa, heats 3 seconds.
Specific performance comparison is as follows:
The soft-package battery processing technology of lamination is cumbersome, cannot be automatic, and efficiency is lower.And 18650 traditional volumes are big, weight
Weight, is rigid shell structure, and mechanical encapsulation is also not suitable for compact apparatus use using relief valve as over-voltage release channel.This Shen
Rechargeable type button soft package lithium battery please, small in size, light-weight, punching press air bag, thermoplastic package utilizes the extension of plastic-aluminum membrane material
Property and special air bag spatial design absorb the pressure generated when inside and outside portion's slight abnormality, work as fault spread, internal pressure is more than
When normal range (NR), internal pressure can be let out at negative electrode lug heat-sealing from just, guarantee that battery will not explode, on fire.
The application is used as shell using plastic-aluminum structure, and processing is more convenient, while quality is lighter, can be with after being completed
It is sealed by thermoplastic package technique, installation effectiveness is high, and security seal performance is good；Using by anode pole piece, diaphragm and cathode
Pole piece is rolled into column core structure, produces and processes more efficient；The anode and cathode of the application is drawn convenient to use from two sides；This
Application uses an aluminum plastic film shell, primary to encapsulate, and is not necessarily to bending without lead angle after encapsulation, production efficiency is lower, safety and stability.
The above, the only preferred embodiment of the utility model, are not intended to limit the utility model, all according to this
The technical spirit of utility model any trickle amendment, equivalent replacement and improvement to the above embodiments should be included in this
Within the protection scope of utility model technical solution.
