Description
Technical field
The utility model relates to a kind of button-shaped ultracapacitor, relates in particular to the button-shaped ultracapacitor of a kind of low internal resistance.
Background technology
Button-shaped ultracapacitor is a kind of novel energy storage device, have that good high-power charge-discharge performance, energy conversion efficiency are high, good temp characteristic, service life cycle is long and the advantage such as environmental protection, and it is widely used in fields such as industrial electronic, communications and transportation, intelligence " three tables ", UPS, electronic toy, tax control machines.
The anode pole piece of current button-shaped ultracapacitor and cathode pole piece are bonded in above shell by conducting resinl, and conducting resinl contacts with the interface that outer cover metal is different material, and contact resistance is higher, and conductivity is poor; Pole piece and the shell fastness of conducting resinl bonding neither be fine, make the internal resistance of button-shaped ultracapacitor higher, and reliability is poor.
Summary of the invention
The purpose of this utility model is to provide the button-shaped ultracapacitor of a kind of low internal resistance that reliability is high.
For achieving the above object, the technical solution adopted in the utility model is: the button-shaped ultracapacitor of a kind of low internal resistance, comprise anode cover, on anode cover, be fixedly connected with negative cover, it is characterized in that: anode cover and negative cover inner laser are welded with anode pole piece and cathode pole piece, between anode pole piece and cathode pole piece, by barrier film, separate, and the contact-making surface of anode pole piece and anode cover is designed with aluminium film, the contact-making surface of cathode pole piece and negative cover is designed with aluminium film, between anode cover and negative cover, is filled with electrolyte.
In this structure, the thickness of described aluminium film is 5 ~ 20 μ m.
The utility model has the advantages of and be: due to this structure of the present utility model, by at anode pole piece and cathode pole piece and housing contacts face vacuum evaporation coating one deck aluminium film, and use Laser Welding that pole piece is welded on product casing, reduced the contact resistance of pole piece and shell, increased the reliability of button-shaped ultracapacitor, and have simple in structure, be beneficial to batch production, feature reasonable in design.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In accompanying drawing: 1, cathode pole piece; 2, anode pole piece; 3, negative cover; 4, barrier film; 5, aluminium film; 6, anode cover.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
The utility model as shown in Figure 1, the button-shaped ultracapacitor of a kind of low internal resistance, comprise anode cover 6, on anode cover 6, be fixedly connected with negative cover 3, it is characterized in that: anode cover 6 and negative cover 3 inner lasers are welded with anode pole piece 2 and cathode pole piece 1, between anode pole piece 2 and cathode pole piece 1, by barrier film 4, separate, anode pole piece 2 is designed with aluminium film 5 with the contact-making surface of anode cover 6, cathode pole piece 1 is designed with aluminium film 5 with the contact-making surface of negative cover 3, between anode cover 6 and negative cover 3, is filled with electrolyte.In the present embodiment, the thickness of described aluminium film 5 is 5 ~ 20 μ m.
