Abstract
The utility model relates to a colloidal battery plate for an electric bicycle, which is characterized in that the porosity of a diachylon coating is 75%-80%; the surface of the coating is provided with concave-convex stripes parallel to the plate lug direction and uniformly distributed; and the space is 1.0-1.5mm, and the depth is 0.4-0.6mm. The colloidal battery plate is used to manufacture a colloidal battery, is beneficial to the pouring and permeation of glue solution with certain viscosity, so that the performance and the service life of the colloidal battery can be effectively improved, and the using requirements of the electric bicycle can be met.
Description
Technical field
The utility model relates to a kind of gelled lead acid battery (abbreviation colloid battery) pole plate that is mainly used in electric bicycle.
Background technology
China is as the electric bicycle producing country of world today's maximum and possess state, how to improve the parts of electric bicycle most critical--the performance and the life-span of battery, become the problem that solution is concerned about and is pressed for to present electric bicycle industry the most.
The colloid battery technology is the history of existing years development abroad, in the man grasp of European number colloid technology company, the most famous with German sunlight company, the colloid battery that the said firm produces with its unique colloid technology has characteristics such as high-performance, long-life, but its production process complexity, the shortcoming that product cost is high has also restricted its product and has used the further expansion in field.
Stem-winding is that through China's lead acid accumulator industry professional's unremitting effort for many years, the electric bicycle of existing battery of electric bicycle technology of a kind of combination and technology is rapidly developed at home with gelled lead acid battery.The colloid battery production process of China is simple and easy to operate, production cost is low, and battery performance is significantly improved than common electrical motor-car battery, and many more strong battery producers all drop into development and the exploitation that the man power and material carries out colloid battery at present.The promotion and application of colloid battery technology in the lead-acid accumulator for electric bicycle field are that living space has been expanded in the development of battery of electric bicycle, also are that the development of the required batteries of electric automobile of China's new-energy automobile industry lays the foundation simultaneously.
Electrolyte is the carrier that electron transfer takes place between the battery plus-negative plate, and the quality of its performance has directly determined the performance and the life-span of battery.The main distinction of colloidal electrolyte and general electrolyte (certain density dilute sulfuric acid) is colloidal electrolyte owing to added supplementary materials such as a certain proportion of aerosil, phosphoric acid, CMC, potash soap in dilute sulfuric acid, and be mixed and processed by certain technology, electrolyte has just become a kind of emulsion with relatively large viscosity from common dilution heat of sulfuric acid like this, the characteristics of emulsion and the thixotropic behavior of glue have changed the characteristic of electrolyte, and have finally promoted the performance of battery.
Battery of electric bicycle has the characteristics of tight assembling, simultaneously between the positive/negative plate barrier film--AMG (ultra-fine fibre glass) barrier film has certain filterability, diffusion to glue with certain viscosity is unfavorable, and the porosity of the pole plate lead plaster coat of existing colloid battery is lower, be generally below 70%, and there is netted decorative pattern on the coat surface, more increased the diffusion difficulty of glue, be in particular in battery perfusion electrolyte difficulty, electrolyte was at polar board surface with the internal penetration time is long and osmotic effect is undesirable when battery changed into, and final result is exactly performance and the life-span that influences battery.
The utility model content
The purpose of this utility model is to overcome the weak point of existing colloid battery pole plate, and a kind of battery liquid-filling and electrolyte permeability of helping is provided, and then improves battery performance and the electric bicycle in life-span colloid battery pole plate.
The technical solution of the utility model is: electric bicycle colloid battery pole plate, comprise grid and lead plaster coat, its improvements are that porosity is 75%～80% after the described lead plaster coat drying, and there is the concavo-convex striped that is parallel to the lug direction on the coat surface.
Described concavo-convex striped evenly distributes, spacing 1.0～1.5mm, the degree of depth 0.4～0.6mm.
The utility model has following advantage compared to existing technology:
1, the utility model has increased water content in the pole plate lead plaster in making, and the porosity that stays behind the moisture loss when later process is dry when pole plate improves, for the diffusion of colloidal electrolyte provides path and place.
2, the utility model is because wet pole plate makes the lead plaster coating form concavo-convex striped from top to down after pushing through the compression roller that has linear marking cloth, flowing to the bottom from battery top for colloidal electrolyte provides passage, the fluid injection speed and the effect of battery have been guaranteed, also increased simultaneously the specific area of pole plate, the charge-discharge performance and the useful life of having improved battery.
3, the utility model is simple in structure, and cost is low, is suitable for promoting the use of, and has very high use value.
Description of drawings
Accompanying drawing is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Referring to accompanying drawing, the both sides of grid 2 are provided with lead plaster coat 3, and the upper side frame of grid is welded with lug 1.During pole plate is produced, with cream the time, add of the apparent density reduction of an amount of deionized water how, guarantee that the lead plaster apparent density is than common lead plaster low 10%～15% lead plaster.Put linear marking cloth on compression roller, the wet pole plate that has just applied lead plaster is through forming tangible concavo-convex striped behind the compression roller, and wet simultaneously pole plate can be removed part moisture in the pole plate through extruding.After the pole plate drying, lead plaster coat porosity reaches more than 75%, and the spacing that the surface forms from top to down is 1.2mm, the concavo-convex striped 4 that is parallel to the lug direction of dark 0.5mm.
Claims (2)
1. an electric bicycle colloid battery pole plate comprises grid and lead plaster coat, it is characterized in that porosity is 75%～80% after the described lead plaster coat drying, and there is the concavo-convex striped that is parallel to the lug direction on the coat surface.
2. by the described electric bicycle of claim 1 colloid battery pole plate, it is characterized in that described concavo-convex striped evenly distributes, spacing 1.0～1.5mm, the degree of depth 0.4～0.6mm.
