Description
Technical field
The present invention relates to a kind of zinc-nickel cell basoid membrane and preparation method thereof, zinc-nickel cell, belongs to zinc-nickel electricity
Pool technology field.
Background technology
Zinc-nickel cell has the characteristics that low self-discharge, low cost, also has opposite as a kind of new rechargeable battery
Higher discharge voltage, can substitute ickel-cadmium cell and Ni-MH battery within the specific limits.With the development of technology, zinc-nickel cell
The features such as discharge-rate is big makes it also have a good application prospect in power tool and electric automobile field.
But zinc-nickel cell there is also it is certain the shortcomings that.The dissolving of such as zinc load, the generation of zinc dendrite, certain
The drastically deterioration of zinc-nickel cell performance can all be caused in degree.In order to reduce the generation of the dissolving of zinc and dendrite, in the prior art
The method of use mainly has the addition in electrode active material to suppress the material of zinc dissolving and zinc dendrite.Add in this mode
The material added is in electrode active material, during battery use, due to the structure of the active material layer of collection liquid surface
Influence, the effect played is very limited.
Corresponding material is added in the electrolytic solution, and it is a kind of side relatively easily acted to suppress zinc dissolving and zinc dendrite
Formula.But the material cost added in the electrolyte is of a relatively high, and the electrolyte composition using when be still liquid electricity
The form of solution liquid plays a role, and zinc is very easy to dissolve in battery system, and the movement in electrolyte system is very quick,
Still easily lead to zinc privileged site in battery to gather, cause the drastically deterioration of zinc-nickel cell cycle life.
The content of the invention
The present invention provides a kind of preparation of the zinc-nickel cell that can improve zinc-nickel cell cycle life basoid membrane
Method.
Zinc-nickel cell it is a further object to provide membrane made from the above method and using the membrane.
Technical solution is as follows used by the present invention solves above-mentioned technical problem：
A kind of zinc-nickel cell preparation method of basoid membrane, includes the following steps：
1) raw material A is mixed with water obtained glue A；The raw material A includes gelatinizing agent, anionic surface activity
Agent；The gelatinizing agent, the mass ratio of anionic surfactant are 1.5-2.5：4-6；The gelatinizing agent for polyethylene oxide,
One or more in polyvinyl alcohol, polycaprolactone, branched polycaprolactone, carboxymethyl cellulose, hydroxyethyl cellulose；Described the moon
Ionic surfactant is neopelex；
Raw material B is mixed with water obtained glue liquid B；The raw material B is one kind or several in KOH, KF, LiOH, NaOH
Kind；
2) polyalkene diaphragm is soaked into 5-10min in glue A, then soaks 5-10min in glue liquid B again, taken out, i.e.,
.
It is a kind of zinc-nickel cell basoid membrane made from the preparation method of the present invention, the colloid membrane use is in zinc
In nickel-based battery, electrolyte can be played the role of, without reusing electrolyte in zinc-nickel cell, and it is same only with colloid membrane
When play the role of membrane and electrolyte, avoid due to caused by electrolyte skewness battery cycle life decline asking
Topic.Said polyolefins membrane can use polypropylene screen, polyethylene film or composite membrane as basement membrane.Composite membrane is PP-PE-PP
Sandwich diaphragm.
Since the film matrix that the colloid membrane of the present invention uses is polyalkene diaphragm, polyalkene diaphragm and gelatinizing agent and alkali
Degree is firmly combined with to play an important role to the cycle life of battery.In the above method, the raw material A include gelatinizing agent, it is cloudy from
Subtype surfactant and couplant；The gelatinizing agent, anionic surfactant, the mass ratio of couplant are 1.5-2.5：
4-6：1-1.5；The couplant is sodium metasilicate, one kind in polysiloxanes.In the colloid membrane preparation process of the present invention, add
Couplant, can fully improve the combination power of gelatinizing agent and alkali on diaphragm matrix surface, and help to ensure that diaphragm matrix surface
Excellent compatibility between each component.Wherein polysiloxanes is preferably dimethyl silicone polymer, it is preferred that its degree of polymerization is generally not
More than 2000.The substance viscosity that the too high polysiloxanes of the degree of polymerization is easy to cause diaphragm matrix surface is excessive, reduces conducting particles
Migration rate, and then reduce battery charge-discharge magnification performance.
In order to improve the compatibility of the other components of gelatinizing agent and membrane surface, meanwhile, use to make colloid membrane
Temperature range is wide as much as possible, and gelatinizing agent is generally used in combination using two or more components.

One kind in element, the gelatinizing agent C are polycaprolactone or branched polycaprolactone.The degree of polymerization of polycaprolactone and branched polycaprolactone
Generally should not be too high, actual experiment the result shows that, after the too high polycaprolactone of the degree of polymerization adds, the high rate performance of battery can be drastically
Decline.Generally, the molecular weight of polycaprolactone or branched polycaprolactone is all below 4000.The molecular weight of polyethylene oxide is 2
Ten thousand or so.The molecular weight of polyvinyl alcohol is 1.6 ten thousand or so.
The raw material B is the mixture of the two or more compositions in KOH, LiOH, NaOH.Preferably, raw material B by KOH with
NaOH is with mass ratio 20-35:1 composition.It is further preferred that raw material B by KOH, LiOH and NaOH with mass ratio 20-35:0.05：
1 composition.
The concentration of glue A should be small as much as possible, generally, the mass fraction of raw material A is 0.5-1% in the glue A.Glue
The concentration of liquid B can be suitably larger, and the mass fraction of raw material B is 21-36% in the glue liquid B.Above-mentioned concentration or quality
Fraction each means, the gross mass of the raw material A either each component of raw material B accounts for the ratio of glue A or glue liquid B gross mass.
Immersion carries out under vacuum in step 2).Vacuum is preferably 0.02MPa-0.03MPa.
It is dried after being taken out in step 2).The drying simultaneously need not be all evaporated by the moisture on membrane, but
Keep that there is certain water content on membrane.Drying generally uses naturally dry 5-8min.At this moment, moisture is on membrane
10-30%.
Zinc-nickel cell basoid membrane made from a kind of above-mentioned method.
A kind of zinc-nickel cell, including cathode, anode, membrane, the membrane for above-mentioned zinc-nickel cell basoid every
Film.
Colloid membrane, wherein colloid is made in membrane surface attachment colloid with basoid membrane in the zinc-nickel cell of the present invention
It is to use colloidal electrolyte made of raw material A and raw material B, contains alkali in the colloidal electrolyte, also containing gelatinizing agent, surface-active
Agent etc., the basoid membrane avoid the mobility of liquid electrolyte, reduce the dissolving of zinc, additionally it is possible to the full extent
The migration of zinc is reduced, and then delays the growth of zinc dendrite.In addition it is possible to reduce positive and negative anodes powder cross contamination, lifting battery holds
Holding capacity is measured, and then lifts battery cycle life.
The zinc-nickel cell basoid membrane of the present invention, can solve dissolving, dendrite and the migration problem of zinc, reduce electricity
