Description
Technical field
The present invention relates to battery manufacturing field, more particularly to a kind of battery separator with inserted rib.
Background technology
Battery separator is placed in battery a kind of dividing plate being made of diaphragm material between positive plate and negative plate,
Play a part of to separate positive plate and negative plate, and can pass through electric current, can effectively prevent positive plate and bear
The battery short circuit problem that pole plate contacts with each other and causes.
The outside of battery separator is provided with rib, the design of rib can not only increase battery separator impact resistance and
Mechanical strength, and rib served during battery separator use supported between positive plate and negative plate enough
The effect in big space, so that there is enough electrolyte in space of the battery when being chemically reacted around pole plate, meets and stores
The need for battery charging and discharging.At present, the rib on battery separator is made of with dividing plate identical material, due to manufacture rib
Material be Ins. ulative material, therefore the electric conductivity of rib is poor, the poor-performing of the battery separator with this rib.
The content of the invention
Goal of the invention：Regarding to the issue above, it is an object of the invention to provide a kind of battery separator with inserted rib,
Make rib that good electric conductivity is also equipped with while playing a supporting role.
Above-mentioned technical purpose of the invention is achieved through the following technical solutions：A kind of battery with inserted rib
Dividing plate, including clapboard body and rib, what the rib was spaced is distributed in one side of the clapboard body towards positive plate, the rib
Including rib one and rib two, the one side and clapboard body of the rib one are integrally formed connection, the one side of the rib two and
The relative another side that rib one is connected with clapboard body is mutually combined, and the material of the rib one is consistent with clapboard body material,
The material of the rib two is the conductive material of the stabilization in sour environment.
By using above-mentioned technical proposal, because rib two is conductive, therefore the muscle of electrical insulating property is compound to
On bar one, make the conductive energy of battery separator rib without conductive capability, this existing certain height of rib originally
There is certain conductive capability again, therefore use it for can not only playing a part of support in battery separator but also can also be pole
Booster action is played in the electric current conveying of plate, improves the charge-discharge performance of battery, shortens the charging interval；Simultaneously as muscle
The material of bar two is the material of the stabilization in sour environment, therefore with the stable performance of this inserted rib battery separator,
Long service life.
Further, the rib one and the mutually compound face of rib two are smooth plane.
By using above-mentioned technical proposal, mutually compound face is that on the one hand smooth plane is conducive to rib one and rib two
Making, the process simplification on the other hand making rib one and rib two-phase compound is conducive to industrialized production.
Further, the rib one is consistent with the width in the face that rib two-phase is combined.
By using above-mentioned technical proposal, because the battery separator with rib one is using the side of polymer extrusion molding
Formula, when manufacture has the battery separator of inserted rib, using while polymer extrusion molding, by rib two from mould
In pass through, and the battery separator with rib one is molded together, therefore, the width one in rib one and the compound face of rib two-phase
Cause, be on the one hand conducive to the making of mould to be on the other hand easy to production and processing.
Further, the width in the rib one and the compound face of rib two-phase is 0.4-0.8mm.
By using above-mentioned technical proposal, the width of rib one and rib two is excessive, can not only make the making of battery separator
Cost increases and the resistance of battery separator can be made to become big, and causing the performance of battery separator reduces, and rib one and rib two
Width it is narrow, then rib one and rib two be difficult make.
Further, the material of the rib two is Graphene.
By using above-mentioned technical proposal, Graphene is nonmetallic materials, although electrically conductive, but electric conductivity is poor,
And Graphene is expensive, making rib two with it can increase the cost of rib.
Preferably, the material of the rib two is argent.
By using above-mentioned technical proposal, the stable chemical nature of argent, not with sulfuric acid reaction, is difficult rotten by chemicals
Erosion, with extraordinary thermal conductivity, the material as rib two can significantly improve the electric conductivity of rib.
Preferably, the material of the rib two is metallic lead.
By using above-mentioned technical proposal, preferably, the corrosivity of resistance to sulfuric acid is good for the electric conductivity of metallic lead, and metallic lead
Cost is relatively low, is adapted to industrialized production.
Further, the total height of the rib one and rib two is 0.5-1.5mm.
By using above-mentioned technical proposal, the height of rib is closely related with the performance of battery separator, and rib height is higher,
The good impact resistance of battery separator, high mechanical strength, conduct electricity very well, but rib excessive height, not only make rib material
Consumption causes greatly production cost too high, and the mechanical strength of cell septum case is also no longer improved with the increase of rib height
Even it is also possible to can reduce；Rib is highly too low, and battery separator mechanical strength is low, the poor performance of battery separator.Therefore, by muscle
The height of bar is set to 0.5-1.5mm can be made the cost of manufacture of battery separator relatively low and can guarantee that battery separator has excellent property
Energy.
Further, the height of the rib one is 0.1-1.3mm, and the height of the rib two is 0.2-1.4mm.
By using above-mentioned technical proposal, rib one it is highly too low, on the one hand increased the difficulty of manufacture on the other hand
Can be compound on rib one to rib two and made troubles, the height of the excessive height of rib one then corresponding rib two will mistake
Low, the manufacture difficulty of rib two becomes big, and the electric conductivity of rib is poor.
Beneficial effect：Compared with prior art, it is an advantage of the invention that traditional battery separator rib is combined into last layer
Conductive material, makes rib conductive, and the rib of this structure not only has traditional supporting role but also can be auxiliary
Helping pole plate carries out the conveying of electric current；Using the battery separator of the rib of this structure, can not only effectively prevent positive plate and
The battery short circuit problem that negative plate contacts with each other and causes, and the electric current conveying of battery positive voltage can be made to obtain significant
Improve.
