To the Ni-MH battery manufacturing industry, improving battery capacity and integrated performance index is eternal topic.Generally adopt roller to make pole piece in the Ni-MH battery manufacturing industry, the application of major diameter roll has directly influenced the raising of battery performance, therefore, how to improve major diameter roll structure, make it more to help continuous roller-compaction, this not only is related to the integrated performance index that improves battery, and simul relation is to enhancing productivity and raw-material utilance.
(3) summary of the invention:
The purpose of this utility model is to design a kind of Ni-MH battery manufacturing industry major diameter texturing roll, it makes the treated texturing structure that becomes of major diameter roll, being solved the major diameter roll and be beneficial to the problem of continuous roller-compaction with further raising battery capacity and performance, is to provide a higher platform to battery design.
The technical solution of the utility model: a kind of Ni-MH battery manufacturing industry comprises the major diameter roll with major diameter texturing roll, it is characterized in that at major diameter roll outer surface the texturing groove that is applicable to the texturing concave point of making positive plate and is applicable to the making negative plate being arranged.
Between the desirable 150-1000mm of roller diameter of above-mentioned said suitable major diameter roll.
Between the desirable spiral of distribution of above-mentioned said texturing concave point and texturing groove, desirable 0 ° ± 90 ° of its lead angle.
Above-mentionedly saidly be applicable to that what major diameter roll outer surface had its texturing concave point diameter of texturing concave point of making positive plate should be between 100-500 μ m, the texturing concave point degree of depth should be between 20-50 μ m; The crosswise spots spacing of texturing concave point should be between 0.5-2.0mm, and vertical dot spacing of texturing concave point should be between 0.2-1.2mm.
The above-mentioned said groove width that is applicable to its texturing groove of texturing groove of making negative plate that has at major diameter roll outer surface should be between 100-500 μ m, the groove depth of texturing groove should be between 20-50 μ m, the separation of texturing groove should vertical dot spacing of texturing concave point be zero with the crosswise spots spacing of texturing concave point, and promptly the separation of texturing groove should be between 0.5-2.0mm.
Operation principle of the present utility model and using method are: the roll after the outer surface texturing can reduce the pole plate elongation significantly and improve compacted density; The reduction of elongation was not strengthened self tensile strength of nickel foam and steel band before winding pole is reeled, thereby helped the high power discharge of Ni-MH battery; The raising of compacted density helps the increase of unit volume active material, thereby battery capacity is significantly improved.Design when because of the roll after the outer surface texturing nickel pole piece being rolled with the metallic hydrogen pole piece in addition is different fully, pointed, and because nickel and metallic hydrogen powder degree size are directly connected to texturing concave point diameter phi
0Size, so the reply roller surface clean.
Superiority of the present utility model is: the roll after the outer surface texturing can be used for continuous roller-compaction operation, utilization rate of raw materials can be brought up to more than 94% by original 70% ~ 80%, saved consumption, reduced cost, adopt this technology greatly to simplify the manufacturing process equipment of battery pole piece simultaneously, equipment input that can small amount is raised labour productivity.
