Abstract
The invention discloses a battery separator with embedded ribs. The battery separator comprises a separator body and the ribs, the ribs are distributed on one surface of the separator body facing a positive electrode plate at intervals, the ribs include first ribs and second ribs, one surface of each first rib is integrally connected with the separator body, one surface of each second rib and the other surface opposite to the connecting surface of the first rib and the separator body are composited, materials of the first ribs are consistent with those of the separator body, and materials of the second ribs are conducting materials which are stable in the acid environments. The battery separator has the advantages that one layer of conducting materials are composited on traditional battery separator ribs, so that the ribs have electrical conductivity, the ribs with the structures have traditional supporting actions and can assist electrode plates to transmit current, the battery separator of the ribs with the structures can effectively prevent short circuit of a storage battery caused by mutual contact of the positive electrode plate and a negative electrode plate, and current transmission of the positive electrode plate of the storage battery is remarkably improved.
Description
Technical field
The present invention relates to battery manufacturing field, particularly to a kind of battery separator with inserted rib.
Background technology
Battery separator is placed on a kind of dividing plate made with diaphragm material in accumulator between positive plate and negative plate,
Play the effect separating positive plate and negative plate, and electric current can be made to pass through, can effectively prevent positive plate and bear
The accumulator 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 serves during battery separator use and supports between positive plate and negative plate enough
The effect in big space, so that there is enough electrolyte in the space around accumulator pole plate when carrying out chemical reaction, meets and stores
The needs of battery charging and discharging.At present, the rib on battery separator is made using with dividing plate identical material, due to manufacturing rib
Material be Ins. ulative material, the electric conductivity of therefore rib is poor, the poor-performing of the battery separator with this rib.
Content of the invention
Goal of the invention:For the problems referred to above, it is an object of the invention to provide a kind of battery separator with inserted rib,
Rib is made to be also equipped with good electric conductivity while playing a supporting role.
The above-mentioned technical purpose of the present invention is achieved through the following technical solutions:A kind of battery with inserted rib
Dividing plate, including clapboard body and rib, what described rib was spaced is distributed in the one side towards positive plate for the clapboard body, described rib
Including rib one and rib two, the one side of described rib one and clapboard body are integrally formed connection, the one side of described rib two and
Rib one is combined with the relative another side phase that clapboard body connects, and the material of described rib one is consistent with clapboard body material,
The material of described rib two is stable conductive material in sour environment.
By adopting technique scheme, because rib two has electric conductivity, therefore it is compound to the muscle of electrical insulating property
On bar one, the battery separator rib originally without conductive capability is made to have an electric conductivity, the existing certain height of this rib
There is certain conductive capability again, therefore use it in battery separator, playing the effect of support and can also be pole
Assosting effect is played in the electric current conveying of plate, improves the charge-discharge performance of accumulator, shortens the charging interval;Simultaneously as muscle
The material of bar two is stable material in sour environment, therefore has the stable performance of this inserted rib battery separator,
Long service life.
Further, described rib one and the mutually compound face of rib two are smooth plane.
By adopting technique scheme, the plane one side that mutually compound face is smooth is conducive to rib one and rib two
Making, the process simplification on the other hand making rib one and rib two-phase be combined, be conducive to industrialized production.
Further, described rib one is consistent with the width in the face that rib two-phase is combined.
By adopting technique scheme, because the battery separator with rib one adopts the side of polymer extrusion molding
Formula, when manufacturing the battery separator with inserted rib, using while polymer extrusion molding, by rib two from mould
In pass through, molding together with the battery separator with rib one, therefore, the width one in the face that rib one and rib two-phase are combined
Cause, be on the one hand conducive to the making another aspect of mould to be easy to production and processing.
Further, the width in the face that described rib one and rib two-phase are combined is 0.4-0.8mm.
By adopting technique scheme, the width of rib one and rib two is excessive, not only can make the making of battery separator
Cost increases and the resistance of battery separator can be made to become big, leads to the performance of battery separator to reduce, and rib one and rib two
Width narrow, then rib one and rib two are difficult to make.
Further, the material of described rib two is Graphene.
By adopting technique scheme, Graphene be nonmetallic materials although electrically conductive, but electric conductivity is poor,
And Graphene is expensive, making rib two with it can make the cost of rib increase.
Preferably, the material of described rib two is argent.
By adopting technique scheme, the stable chemical nature of argent, not with sulfuric acid reaction, it is difficult rotten by chemicals
Erosion, has extraordinary heat-conductivity conducting, and the material as rib two can significantly improve the electric conductivity of rib.
Preferably, the material of described rib two is metallic lead.
By adopting technique scheme, preferably, the corrosivity of resistance to sulphuric acid are good for the electric conductivity of metallic lead, and metallic lead
Cost is relatively low, suitable industrialized production.
Further, the total height of described rib one and rib two is 0.5-1.5mm.
By adopting technique scheme, 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 the excessive height of rib, not only make rib material
Consumption leads to greatly production cost too high, and the mechanical strength of cell septum case also no longer improves 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 described rib one is 0.1-1.3mm, and the height of described rib two is 0.2-1.4mm.
By adopting technique scheme, the height of rib one is 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 make troubles, then the height of rib two will mistake accordingly for the excessive height of rib one
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 last layer
Conductive material, makes rib have electric conductivity, the rib of this structure not only has traditional supporting role but also can be auxiliary
Pole plate is helped to carry 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 accumulator 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 significantly
Improve.
