Description
Technical field
The relevant a kind of porousness collector metal structure of the utility model, refer to especially a kind of can with appearance side coating active material strong bonded, and form the collector metal structure of low internal resistance combination.
Background technology
Along with the progress of various material science and technology, metal collector (aluminium foil, the Copper Foil) structure that is applied in lithium ion battery (LiB), lithium-ion capacitance (LiC) and the super capacitor also produces variation greatly thereupon.
Because the function of above-mentioned metal collector is conduction (lithium ion battery, lithium-ion capacitance and super capacitor) the external electric current of exporting, therefore, the fundamental characteristics that must meet low internal resistance (and ion is easy to penetrate) on its structure, and for satisfying the demand characteristic, more common structure has as shown in Figure 1 at present, it is with foil material 10(aluminium foil, Copper Foil) Surface Machining is for having rough roughening structure 101, when making this follow-up active material 20 coat these foil material 10 surfaces, can form bigger contact area via this rough roughening structure 101, use the whole internal resistance of effective reduction, and can make between this active material 20 and the foil material 10 and have preferable bond strength.
Other has structure as shown in Figure 2, be in foil material 100(aluminium foil, Copper Foil) on the perforation perforation 102 of dense arrangement is set, the active material 200 of coating these foil material 100 2 side surfaces can be communicated with via each 102 formation of boring a hole, by this, form between active material 200 and the foil material 100 the better bond strength except making, also with the effect that reduces internal resistance.
Yet, be set forth in foil material 10 surfaces on no matter being and form rough roughening structure 101, or bore a hole 102 structure of intensive row is set on this foil material 100, it is all comparatively limited that it can reach the effect of promoting bond strength or reducing internal resistance, generally speaking, still have the great space of improving.
Because the collector metal structure of having seen has above-mentioned shortcoming, the designer is the road at these shortcoming research improvement, has the utility model to produce finally.
Summary of the invention
The utility model main purpose is to provide a kind of porousness collector metal structure, and it is compared to traditional dependency structure, except can between this foil material and its surface coating active material, producing the better bond strength, and with lower internal resistance.
For reaching above-mentioned purpose and effect, the practiced technological means of the utility model comprises: a kind of porousness collector metal structure, it comprises at least: a laminar metal material body, at least one side surface in this metal material body is provided with roughened surface, and is provided with most perforation that connect two side surfaces in this metal material body.
According to said structure, wherein this metal material body all is provided with roughened surface in two side surfaces.
According to said structure, wherein be laid with an active material layer in this metal material body appearance side, this active material layer is except can amassing than large contact surface via roughened surface and the formation of this metal material body appearance side, this active material layer also can be interconnected via each perforation, to produce preferable bond strength.
According to said structure, wherein this metal material body is for being selected from one of them thin sheet of metal of aluminium foil, Copper Foil at least.
According to said structure, wherein this metal material body is for being selected from one of them thin sheet of metal of aluminium foil, Copper Foil at least.
According to said structure, after wherein this metal material body is finished processing, furl into a drum.
According to said structure, after wherein this metal material body is finished processing, furl into a drum.
According to said structure, wherein roughened surface is the concavo-convex roughened surface of rule.
According to said structure, wherein roughened surface is irregular concavo-convex roughened surface.
Compared with prior art, the beneficial effect that the utility model has is: the utility model metal material body appearance side is coated with an active material layer, this active material layer can form long-pending than large contact surface via roughened surface and metal material body appearance side, with its internal resistance of effective reduction; And this active material layer also can be interconnected via each perforation, uses the bond strength that increases itself and metal material body.Simultaneously, the metal material body can be furled into a drum after finishing processing, except can being convenient to harvesting, also can utilize the characteristics of its lasting discharging, helps follow-up automated machine processing.
For can being obtained more specifically, the utility model above-mentioned purpose, effect and feature understand, and as follows according to following description of drawings now.
