Description

Button ultracapacitor
Technical field
The present invention relates to electrochemical energy technical field, relate to a kind of button ultracapacitor specifically.
Background technology
Along with sharp increase and the socioeconomic fast development of population, resource and the energy are day by day short, and environmental protection comes into one's own day by day, and the exploitation of the energy and saving become an important topic of the world today.The energy is the basis of human society Existence and development, and the society based on fossil energy meets with energy shortage and environmental pollution crisis more and more continually.Meanwhile, along with the arriving of information-based cyberage, energy source use form changes, and renewable, pollution-free, small-sized discrete removable high-performance power supply requirement increases fast.In the market common cell system as: the primary cells such as alkali manganese, silver-colored zinc, its common features such as plumbic acid, NI-G, ni-mh, lithium ion battery have higher energy density, but their power density is very low, and the charging interval is long.Thus many energy storage device applications higher to power density requirements (as space industry and sophisticated weapon equipment etc.), these traditional storage batterys not can satisfy the demands.Therefore people wait in expectation and have the appearance of high-energy, high power, long-life novel green energy storage device.
Button-shaped ultracapacitor, as a kind of energy-storage travelling wave tube, is widely used on the back-up source of instrument and meter and clock, and it has the feature of charging interval short, long service life, good temp characteristic, energy savings and environmental protection.At present, during button-shaped ultracapacitor assembling, after positive and negative electrode shell and pole piece are bondd, for ensureing its electric conductivity, need to carry out high-temperature heat treatment; Positive and negative electrode shell sealed, sealing ring is provided with in both junctions, and the restriction of sealing ring heat-treated temperature, after needing heat treatment, sealing ring is placed on shell, assembling process is loaded down with trivial details, and there is the problem that leakage rate is high, cause greatly shorten its useful life, easily environment for use is polluted.In addition, also there is a problem and be exactly in current super button capacitor, time long in use, there will be the problem heaved, have impact on the use of appearance, cause potential safety hazard.
Utility model content
In order to solve above-mentioned technical problem, the utility model proposes a kind of button ultracapacitor, its objective is the problem solving existing button ultracapacitor and seepage easily occurs and to heave etc.
To achieve the above object, basic technical scheme of the present utility model is: a kind of button ultracapacitor, comprise the anode cover and negative electrode casing that mutually fasten and form accommodating cavity, described anode cover and negative electrode casing junction are provided with sealing ring, be provided with barrier film in the middle of described accommodating cavity and described accommodating cavity isolation is become positive pole cavity and negative pole cavity, described positive pole cavity and negative pole cavity fill electrolyte, described positive pole cavity is provided with positive pole electricity sheet, described negative pole cavity is provided with negative electricity sheet, described anode cover and positive pole electricity sheet between or be provided with lining shell between negative electrode casing and negative electricity sheet, described anode cover and described negative electrode casing are provided with reinforcement groove, the outside riveting of described anode cover and described negative electrode casing has positive pole pin and negative pole pin.
In button ultracapacitor described in the utility model, described lining shell is network structure lining shell.
In button ultracapacitor described in the utility model, described reinforcement groove is to accommodating cavity sunken inside.
In button ultracapacitor described in the utility model, the cup depth of described reinforcement groove is 0.2 ~ 0.5mm.
In button ultracapacitor described in the utility model, the leads ends of described positive pole pin and described negative pole pin is arranged on the same side of anode cover or negative electrode casing.
The beneficial effects of the utility model:
The utility model is designed with lining shell, by lining shell to the iris action of electrolyte, prevents exosmosing of electrolyte; In addition, be also provided with reinforcement groove, enhance the stressed of anode cover and negative electrode casing by strengthening groove, increasing the area of anode cover and negative electrode casing simultaneously, reducing interior resistance; Moreover, realized the connection of positive pole pin and anode cover, negative pole pin and negative electrode casing by the mode of riveting, avoid the drawback be welded to connect in the past.
Accompanying drawing explanation
Fig. 1 is the internal structure schematic diagram of button ultracapacitor described in the utility model;
Fig. 2 is the outside drawing of button ultracapacitor described in Fig. 1.
Embodiment
Below with reference to accompanying drawing 1 and accompanying drawing 2, the present invention is described further, but should not limit the scope of the invention with this.
