Description
Technical field
The present invention relates to zinc-nickel cells, more particularly, to a kind of new types of diaphragm paper bag for wrapping up cathode in battery.
Background technology
Battery diaphragm refer in a kind of material for preventing positive and negative anodes short circuit between battery plus-negative plate, be in battery very
Crucial part, has a direct impact battery security, service life and cost, main function is：Isolation positive and negative electrode prevents its object
Reason contacts and prevents the electronics in battery from passing freely through, and the ion in electrolyte is allowed to be passed freely through between positive and negative anodes.Battery
The ionic conductivity of diaphragm is directly related to the overall performance of battery, and the effect of isolation positive and negative anodes makes battery excessively fill
The raising that electric current can be limited in the case of electricity or temperature are raised, prevents battery short circuit from setting off an explosion, and has the self-closing protection of micropore
Effect, plays the role of safeguard protection to battery user and equipment.
For zinc-nickel cell, the selection and use of diaphragm will not only consider above-mentioned performance parameter, it is also contemplated that diaphragm sheet
Three weeks edge sealing of body, for the characteristic of zinc-nickel cell, diaphragm cannot use traditional coating mode, conventional lithium ion battery or nickel
Stacked and takeup type can be used in hydrogen battery etc., is isolated using single-layer septum between positive/negative plate, and zinc-nickel cell then needs
Consider the dissolving for preventing the generation of zinc dendrite, being in direct contact caused zinc load with electrolyte to the absorption of electrolyte and negative plate
With accelerate the growing of dendrite, zinc oxide changes the scrambling etc. of zinc in charging process；It need to be good using absorbency to positive diaphragm
Cut surrounding except at lug other be fully sealed, negative electrode membrane, which is required to meet outside above-mentioned performance, will also have dendrite inhibition and hydrophilic,
Surrounding except at lug other be fully sealed.
Invention content
Present invention aim to address problems set forth above, provide leakproofness a kind of good new types of diaphragm paper bag.
Realize that the technical solution of the object of the invention is a kind of new types of diaphragm paper bag, including diaphragm, zinc load, the diaphragm packet
The zinc load is covered, the lug of the zinc load is located at the outside of diaphragm.
A kind of method of new types of diaphragm paper bag is prepared, is included the following steps：
A, ultrasonic wave host turns on the switch simultaneously test sound wave；
B, measuring air pressure device, after determining that workbench ventilation is normal, adjustment pneumatic shuttle to air pressure detection table can normal work
Make；
C, diaphragm fixing device is adjusted, the diaphragm for needing to tailor is taken out, is put into fixing device, it is ensured that diaphragm is placed vertically,
Pedestal is rotatable, can work normally；
D, diaphragm positioning device is adjusted, after the preparation of step C is carried out, positioning device is sent into diaphragm doubling, is doubling
Positioning device is close in face bottom, can work normally；
E, ultrasonic wave making mold carries out replacing corresponding upper die head according to the model diaphragm to be made；
F, ultrasonic wave bag making after the above preparation is carried out, can start bag making, and diaphragm is extended to determining for required length
Bit line, both hands are located at both sides and slightly give point a same outward force, and right crus of diaphragm unclasps after stepping on switching cylinder, at this time sack ultrasonic wave
Bag making is completed；
G, ultrasonic wave bag making finished product, it can be seen that both sides seal smooth, no wave, and flanging is relatively narrow；
H, ultrasonic sealing, ultrasonic wave bag making finished product finger are given external force and are occurred without visible gap, and fill water and test nothing
Water droplet occurs.
It is 3, according to claim 2 to prepare a kind of method of new types of diaphragm paper bag, it is characterised in that：The step B
The air pressure detection table of middle pneumatic shuttle is 60Kpa：
The present invention has the effect of positive：Sealing means using the present invention mainly have the advantage that：
1) sealing is securely regular.It avoids causing sealing area big with glue sealing and irregular and hot-melting sealed causes to bear
The different degrees of deformation of pole diaphragm.
2) equipment is simple, is easy to purchase.There is standardized product in ultrasonic sealing equipment Market of the present invention, cooperation is certainly
The main upper/lower die designed and developed.
3) easy to operate.In entire manufacturing process, can one-pass molding, positioning tool carry out after can guarantee product sealing
Property, consistency and efficiency.
