Abstract
The utility model relates to a battery separator. The battery separator comprises a substrate, wherein first ribs are uniformly arranged on the upper surface of the substrate; a layer of glass fiber cotton is arranged above the first ribs; second ribs are uniformly arranged on the lower surface of the substrate; the section of each first rib takes the shape of an isosceles triangle; the section of each second rib takes the shape of an isosceles trapezoid; the first ribs and the second ribs are arranged in a staggered manner. The battery separator has higher strength, simultaneously can absorb active substances falling off from a battery plate, prolong the service life of a battery, and reduce the cost.
Description
Technical field
The utility model relates to a kind of dividing plate, specifically a kind of battery separator.
Background technology
Battery comprise the dividing plate between anode and negative electrode and prevent anode and negative electrode between short circuit, when this dividing plate of conductive particle bridging or dividing plate are deteriorated to while allowing electrode contact, can be short-circuited.Effectively battery separator should the various electrolytical existence in there is battery under chemically stable, physics is durable and freely allow ion to flow in whole battery.In battery operated process, the battery pole plates part active material that can come off, is deposited on dividing plate or other positions, causes battery operated unstablely, damages battery, brings potential safety hazard.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of battery separator, and its intensity is larger, can adsorb the active material coming off on battery pole plates simultaneously, has increased the useful life of battery, has saved cost.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of battery separator, comprise substrate, wherein, described substrate upper surface is evenly provided with the first rib, the first described rib top is provided with layer of glass cotton, and described substrate lower surface is evenly provided with the second rib, and the cross sectional shape of described the first rib is isosceles triangle, the cross sectional shape of described the second rib is isosceles trapezoid, and described the first rib and the second rib are crisscross arranged.
Above-mentioned a kind of battery separator, wherein, the base width L of described the first rib is greater than the base width l of the second rib.
Above-mentioned a kind of battery separator, wherein, the height H of described the first rib is greater than the height h of the second rib.
Above-mentioned a kind of battery separator, wherein, the isosceles trapezoid base angle that described the second section of ribs is is 60 °.
The beneficial effects of the utility model are:
1. pair rib setting, is crisscross arranged, and has greatly strengthened the intensity of battery separator, has increased useful life.
2. the first rib top is provided with layer of glass cotton, can adsorb the active material coming off on battery pole plates, makes it to be unlikely to precipitation, has increased the useful life of battery, has greatly saved cost.
Accompanying drawing explanation
Fig. 1 is cutaway view of the present utility model
Embodiment
A kind of battery separator as shown in the figure, comprise substrate 1, wherein, described substrate 1 upper surface is evenly provided with the first rib 2, the first described rib 2 tops are provided with layer of glass cotton 3, under described substrate, 1 surface uniform is provided with the second rib 4, the cross sectional shape of described the first rib 2 is equilateral triangle, the cross sectional shape of described the second rib 4 is isosceles trapezoid, the isosceles trapezoid base angle that described the second rib 4 cross sections are is 60 °, the base width L of described the first rib 2 is greater than the base width l of the second rib 4, described the first rib 2 height H are greater than the second rib 4 height h, described the first rib 2 and the second rib 4 are crisscross arranged.
This structure adopts two rib settings, is crisscross arranged, and has greatly strengthened the intensity of battery separator, has increased useful life.The first rib top is provided with layer of glass cotton, can adsorb the active material coming off on battery pole plates, makes it to be unlikely to precipitation, has increased the useful life of battery, has greatly saved cost.
Here description of the present utility model and application is illustrative; not want by scope restriction of the present utility model in the above-described embodiments; therefore, the utility model is not subject to the restriction of the present embodiment, and the technical scheme that any employing equivalence replacement obtains is all in the scope of the utility model protection.
