Description
Technical field
The production method and the battery thereof of button lithium battery box hat of the present invention belong to field of batteries, particularly relate to a kind of button lithium battery.
Background technology
Button lithium battery is of wide application at present, but its performance also needs further improvement.Particularly button lithium battery is in storage process, and performances such as the voltage of battery and internal resistance constantly worsen.Through finding after the long term studies that the deterioration of button lithium battery performance and the outer package box hat of battery have very large relation.Usually in the technology, the material of the outer package box hat of button lithium battery is a stainless steel, represents model as 304,316 etc., is lower than at voltage under the current potential of 3.6V, and stainless steel electrochemical corrosion can not take place.Yet the whole operating voltage range of button lithium battery between 1.5V～4.3V, stainless steel generation electrochemical corrosion under high potential, the consequence of corrosion causes self-discharge of battery big, the internal resistance of battery simultaneously also can be risen, and makes the mis-behave of battery.In the whole operating voltage range of button lithium battery, with electrochemical corrosion not taking place or the button lithium battery box hat of electrochemical corrosion takes place hardly, can effectively avoid performances such as the voltage of battery and internal resistance constantly to worsen.
Summary of the invention
The objective of the invention is to avoid weak point of the prior art and a kind of anti-corrosion of metal layer that high oxidation potential is arranged is provided, can greatly improve the box hat and the production method thereof of self-discharge performance with the button lithium battery that reduces the internal resistance of cell of battery.
The object of the present invention is to provide the button lithium battery that the anti-corrosion of metal of high oxidation potential layer is arranged on a kind of box hat.
Purpose of the present invention reaches by following measure, the box hat of button lithium battery is the outer package shell, comprise box hat that contacts with anode and the box hat that contacts with battery cathode, the box hat that contacts with anode separates by the insulated enclosure circle with the box hat that contacts with battery cathode, the inner surface of box hat and battery are just, the negative pole contact, on the inner surface of box hat, apply anti-corrosion of metal layer with high oxidation potential, the anti-corrosion of metal layer adopts the metal material that electrochemical corrosion takes place hardly, electrochemical corrosion does not take place under the whole operating voltage range of button lithium battery, prevent to cause self-discharge of battery big, stop the internal resistance of battery to be risen, effectively keep the performance of battery.
On the inner surface of box hat, apply anti-corrosion of metal layer with high oxidation potential, can adopt by the film forming on the surface of box hat of electric plating method in the aqueous solution, also can adopt vacuum coating method film forming on the surface of box hat, also can adopt heat spraying method on the surface of box hat, to form anticorrosive coat.Electric plating method, vacuum coating method, heat spraying method are methods commonly used in the prior art, also can adopt other method film forming on the surface of box hat in the prior art.
The anti-corrosion of metal layer adopts metallic aluminium or Titanium, under metallic material of aluminum Al, the titanium Ti high potential electrochemical corrosion takes place hardly.Because metallic aluminium and titanium can't be by electric plating method in the aqueous solution in the stainless steel surfaces film forming, metallic aluminium and titanium can adopt vacuum coating method film forming on the surface of box hat, and metallic aluminium and titanium also can adopt heat spraying method to form anticorrosive coat on the surface of box hat.
The anticorrosive coat of metallic aluminium or titanium can carry out on the stainless steel band before the box hat moulding, forms the box hat with metallic aluminium or titanium anticorrosive coat by punching press then.
The anticorrosive coat of metallic aluminium or titanium also can be after punching press forms the stainless steel box hat, metallizing anticorrosive coat on the surface of box hat.
On the inner surface of the box hat that contacts with anode, apply anti-corrosion of metal layer, on the inner surface of the box hat that contacts with battery cathode, apply anti-corrosion of metal layer with high oxidation potential with high oxidation potential.
Button lithium battery comprises battery steel shell, the electricity core is formed, box hat is the outer package shell, comprise box hat that contacts with anode and the box hat that contacts with battery cathode, the box hat that contacts with anode separates by the insulated enclosure circle with the box hat that contacts with battery cathode, the inner surface of box hat and battery are just, the negative pole contact, the electricity core is anodal, negative pole and the porous isolating membrane composition that plays insulating effect, inject organic electrolyte at electric in-core, anodal, negative pole and barrier film are formed electric core by the mode of lamination, anodal, negative pole and barrier film are also formed electric core by winding method, on the inner surface of box hat, apply anti-corrosion of metal layer with high oxidation potential, the anti-corrosion of metal layer adopts metallic aluminium or Titanium, metallic aluminium and titanium can adopt vacuum coating method film forming on the inner surface of box hat, and metallic aluminium and titanium also can adopt heat spraying method to form anticorrosive coat on the inner surface of box hat.
The present invention can greatly improve the self-discharge performance of battery and reduce the internal resistance of battery, is a kind of button lithium battery with good electrical chemical preservation performance.
