Abstract
The utility model relates to a kind of button cell, the battery includes strip positive and negative plate, insulating film will be arranged between positive and negative plate and winds basis of formation battery core by center axis of positive/negative plate width direction, and pours into electrolyte；It is coated on outside basic battery core using plastic-aluminum packaging film again, the round slot position for being put into sealing edge die carries out heating edge sealing；Finally the battery after edge sealing is put into after die-cutting mould uses the trimming of cross cutting mode and is shaped to finished battery.Battery described in the utility model can realize that diameter is less than 20mm, and the production of button cell of the thickness less than 10mm solves the problems, such as that existing hard shell battery can not minimize.Battery battery core described in the utility model is different from conventional winding method but strip positive/negative plate is used to wind by axis of width direction, battery core shape is easier to control, and size is easier to minimize, and is conducive to subsequent edge sealing and trimming operation, it ensure that product quality simultaneously, improve production efficiency.
Description
Technical field
The utility model relates to a kind of flexible package button cells.
Background technique
Currently, button cell is divided into chemical cell and physical battery two major classes, wherein chemical cell application is more universal, changes
Battery is learned generally to be made of anode (anode), cathode (cathode) and its electrolyte etc..The shell of battery is stainless steel substrates, and is made
For anode, cathode is fabricated to the circular lid of stainless steel, there is sealing ring insulation between positive electrode and negative electrode, and sealing ring has removed insulating effect
Outside, it is also used to that electrolyte is prevented to leak.Since its encapsulation is using the packaged type of physical clogging stiffened shell, packaging effect is simultaneously
Unstable and security performance is poor.
Utility model content
In view of the above-mentioned problems, the utility model provides a kind of Soft Roll button cell packed using plastic-aluminum packaging film.
The utility model technical solution to be protected are as follows: a kind of button cell, the shell including battery core and outside battery core
Body, which is characterized in that the shell is plastic-aluminum packaging film by soft-shell made of cross cutting, and the battery core includes positive and negative plate
And the insulating film between positive/negative plate, electrolyte is equipped between positive and negative plate and insulating film.
Preferably, the positive/negative plate winds basis of formation battery core by center axis of width direction.
Specifically, further including anode ear and negative electrode lug, the positive and negative tab is respectively welded with positive and negative plate.
Preferably, the button cell diameter is less than 20mm, and thickness is less than 10mm.
Compared with prior art, the beneficial effects of the utility model are as follows:
(1) button cell described in the utility model does shell using plastic-aluminum packaging film, can effectively reduce button cell cost,
The more convenient control of the dimensional thickness of button cell simultaneously, it is easier to production miniaturization or slimline battery.
(2) battery battery core is different from conventional winding method but uses strip positive/negative plate using width direction as axis
Winding, battery core shape is easier to control, is conducive to subsequent edge sealing and trimming operation.
Detailed description of the invention
Fig. 1 is schematic diagram of cell structure described in the utility model；
Fig. 2 is finished battery structural schematic diagram.
Specific embodiment
Button cell described in the utility model is described in further detail below in conjunction with specific embodiments and drawings.
Button cell described in the utility model includes battery core and the shell outside battery core, and wherein shell is plastic-aluminum packet
Film is filled by soft-shell made of cross cutting, the battery core is by strip positive and negative plate and the insulating film between positive/negative plate
It is that center axis winds to form battery core bodies 10 along positive and negative plate width direction, electrolyte is equipped between positive and negative plate and insulating film,
Another positive and negative electrode on piece is respectively welded positive and negative tab 20, and unencapsulated preceding battery core is as shown in Figure 1.
The button cell the production method is as follows:
(1) strip positive and negative plate is taken, will insulating film be set between positive and negative plate and is with positive/negative plate width direction
Central axis winds basis of formation battery core.
(2) it is coated on outside basic battery core using plastic-aluminum packaging film, the round slot position for being put into sealing edge die carries out heating envelope
Side, first incomplete edge sealing when edge sealing, reserves the liquid injection port of electrolyte, inject after electrolyte place into sealing edge die carry out it is complete
Edge sealing；
(3) battery after edge sealing is put into die-cutting mould using finished battery is shaped to after the trimming of cross cutting mode, such as Fig. 2 institute
Show, the semi-finished product battery after trimming by there are edge bending be coated on around battery core, the bending of positive and negative tab 20 is in button cell
A 10 ' end face, and conducting wire is respectively welded and draws electrode.
Soft-package battery field usual way can be used in the part not specifically described in the utility model, therefore does not repeat.
Although the description combination embodiments above to the utility model carries out, it is familiar with the art
Personnel can carry out many replacements based on the above contents, modifications and variations, be obvious.Therefore, all such
Substitution, improvements and changes are included in the spirit and scope of appended claims.
