Abstract
The utility model relates to an electrically conductive polar material field discloses a corona aluminium foil of no oxide layer in surface, and it includes: the wetting tension attachment surface of aluminium foil top layer for forming behind no oxidation corona treatment, and this wetting tension attachment surface does not have alumina layer. The utility model discloses electric conductivity is good, and the conductivity is high to battery quality has been improved.
Description
Technical field
The utility model relates to conduction polar material, especially a kind of corona aluminium foil through corona treatment rear surface non-oxidation layer.
Background technology
At present, for the aluminium foil of lithium ion battery conduction polar material when coating polar material (as: Delanium, native graphite, calcined coke, LiMn2O4, cobalt acid lithium), moistened surface tension force (unit: dyne) is inadequate, the powder coating formed adheres to insecure, became uneven is even, easy stripping, impact conduction and current collection performance.The wetting tension adhesive force that can have to make aluminium foil surface, aluminium foil surface is by conventional corona treatment process, make its surface formation have wetting tension reach the wetting tension attachment surface (namely increasing its surface roughness) of more than 34 dyne values and attached one deck aluminium oxide Al 2O3 simultaneously, it is easy to operate, cost is low, but the alumina layer that shortcoming is aluminium foil surface can increase the resistance of aluminium foil surface, reduce conductance, after manufacturing a finished product, the oxide layer of aluminium foil surface continues alumina foil, thus affects battery quality.
Summary of the invention
The utility model object, in order to solve the weak point of above-mentioned existence, provides a kind of corona aluminium foil of surperficial non-oxidation layer, solves existing corona aluminium foil and causes because having alumina layer the resistance on its surface to increase, and reduces conductance, affects the problems such as battery quality.
In order to achieve the above object, the utility model comprises: aluminium foil, and described aluminium foil top layer is the wetting tension attachment surface formed after non-oxidation corona treatment, and this wetting tension attachment surface does not have alumina layer.
The utility model and prior art ratio, its good conductivity, conductance is high, and improves battery quality.
Accompanying drawing explanation
Fig. 1 is structure chart of the present utility model.
Fig. 2 is that the utility model manufactures schematic diagram.
Embodiment
As shown in Figure 1, the utility model comprises: aluminium foil 1, and aluminium foil 1 top layer is the wetting tension attachment surface 2 with non-oxidation aluminium lamination, namely increases its surface roughness, and the adhesive force of this wetting tension attachment surface 2 reaches 30-34 dyne value.
As shown in Figure 2, above-mentioned aluminium foil 1 at the uniform velocity passes in the centre of a casing, and in casing, be filled with gaseous inert gas and keep malleation to isolate oxygen, now, upper and lower semi-conducting electrode corona discharge bombardment aluminium foil two sides in casing, make aluminium foil surface form wetting tension attachment surface, and this wetting tension attachment surface non-oxidation aluminium lamination produce.
The another kind of manufacture of above-mentioned aluminium foil: need the environment of integral production aluminum foil equipment to vacuumize, then carry out corona treatment.
Comprehensively above-mentioned, the utility model can meet the wetting tension adhesive force producing and require, and has good conductivity, and conductance is high, and improves the advantages such as battery quality.
