Description
Technical field
This utility model relates to supercapacitor technologies field, is a kind of button-shaped ultracapacitor, especially a kind of button
Formula ultracapacitor cascaded structure.
Background technology
Ultracapacitor is a kind of Novel energy storage apparatus, has that charge/discharge rates is fast, specific power is high, has extended cycle life, makes
By plurality of advantages such as temperature range width, energy-conserving and environment-protective, be widely used at present automobile, wind-power electricity generation, urban light rail, subway,
The fields such as solar energy, intelligent three tables, tax-control cash register, electric tool, UPS and heavy industry equipment.
Conventional button-shaped ultracapacitor series system is as shown in Figure 1: use electric resistance welding two monolithic capacitors it
Between weld one piece of 0.2-0.5mm thickness nickel strap 1 connect.The reason basic nothing of this series system due to structure and welding manner
Method reduces contact ESR value, weld strength cannot be protected, and welding efficiency is extremely low, and product quality is difficult to ensure, and is difficult to be formed
Batch production.
Utility model content
The purpose of this utility model is to provide a kind of button-shaped ultracapacitor series connection Welding Structure, uses the directly side of welding
Formula realizes series connection, to reduce artificial and material cost, Simplified flowsheet, and applicable automated production, improves production efficiency and product
Quality.
This structure not only ensures that the intensity that monomer electric capacity welds more can improve production effect with the low ESR of contact value, anti-extrusion
Rate, products quality guarantee.The purpose of this utility model is to provide a kind of brand-new button-shaped ultracapacitor series connection welding manner, reaches
To reduce equipment cost,
This utility model solves the technical problem that and be the technical scheme is that
A kind of button-shaped ultracapacitor series connection Welding Structure, including the two panels super button capacitor mutually concatenated, its
Feature be two panels monolithic super button capacitor be the ultracapacitor of different definition polarity, the most a piece of monolithic button is super
The shell end of capacitor is positive pole, and the shell end of the most a piece of monolithic super button capacitor is negative pole, described two panels list
The shell end face laminating of sheet super button capacitor, by Laser Welding at the faying surface edge of two panels monolithic super button capacitor
Position uniform welding.
As preferably, the above-mentioned faying surface marginal position at two panels monolithic super button capacitor is uniformly provided with 4-10 weldering
Contact.
This utility model series system has been carried out after shell end face is defined as opposed polarity owing to using two panels capacitor
Full weight is closed, and reduces the contact ESR value between capacitor, and series connection properties of product are stable.Product at button-shaped ultracapacitor
In production process, use multiple monomer electric capacity carry out series connection be carry high-tension.Assembled in series at ultracapacitor produces work
In skill, not only need contact internal resistance value, the weld strength considering between monomer electric capacity, and need high efficiency, stable production
Mode.Therefore stability, the automaticity of equipment is proposed the highest requirement.Use structure of the present utility model, due to
Eliminating the nickel strap series connection of prior art, two panels capacitor directly welds, and two panels capacitor can be overlapping by easy fixture
After weld, sword soul production equipment, be also very easy to realize the production of automatic production line, it is possible to farthest simultaneously
Reduce production cost and constant product quality is secure.
The beneficial effects of the utility model are: the technical solution of the utility model provides a kind of efficient, stable button
Formula ultracapacitor series connection welding manner, series connection welding manner can simplify manufacturing process, and be highly suitable for automatization's batch
Producing, production efficiency is high, and capacitance contact ESR value is little, constant product quality.
Accompanying drawing explanation
With embodiment, utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of prior art button-shaped ultracapacitor series system.
Fig. 2 is the structural representation of this utility model embodiment.
In figure: 1, nickel strap a, upper super button capacitor b, lower super button capacitor c, pad a1, shell end
One a2, electrode slice one b1, shell end two b2, electrode slice two.
Detailed description of the invention
Referring to shown in Fig. 2, a kind of button-shaped ultracapacitor series connection Welding Structure, including upper super button capacitor a
It is the super of different definition polarity with lower super button capacitor b, upper super button capacitor a and lower super button capacitor b
Capacitor, shell end one a1 of upper super button capacitor a is positive pole, and electrode slice one a2 in other end face is negative pole；Lower knob
Shell end two b1 of button ultracapacitor b is negative pole, and electrode slice two b2 in other end face is positive pole.Upper super button capacitor
The shell end two b1 face laminating of shell end one a1 and lower super button capacitor b of a, by Laser Welding at upper button super capacitor
The faying surface marginal position uniform welding of device a and lower super button capacitor b, it is equal at faying surface marginal position by Laser Welding
Even it is provided with 4-10 pad c.
Finally it is pointed out that above example is only the more representational example of this utility model.Obviously, this practicality is new
Type is not limited to above-described embodiment, it is also possible to have many deformation.Every according to technical spirit of the present utility model to above example
Any simple modification, equivalent variations and the modification made, is all considered as belonging to protection domain of the present utility model.
