Abstract
An integral packaging structure for a super capacitor of the utility model belongs to capacitor members, and comprises a super capacitor end cover, a current collector and a super capacitor cover plate leading-out structure, wherein the super capacitor end cover comprises a cover plate which is provided with an electrode tip hole, a liquid injection hole and a welding strip, a sealing sheet is tightly fitted and connected in the liquid injection hole, and an insulation isolation sealing ring is arranged on the electrode tip hole. The sealing sheet not only acts as a sealing member of the super capacitor, but also has an explosion-preventing function, when an internal pressure of the super capacitor increases to a certain degree, a self-failure damage occurs on the sealing sheet so as to release the internal pressure of the super capacitor and prevent the super capacitor from explosion; the current collector not only can be tightly connected with a protuberant foil, but also has a small welding ESR (Equivalent Series Resistance) value, thereby ensuring that electrolyte solution is fully penetrated to the whole core covering of the super capacitor during an electrolyte solution perfusion work process; and the cover plate leading-out structure is newly designed, and has the advantages of simple structure, good sealing performance, and high working efficiency. Therefore, the integral packaging structure of the utility model has the advantages of small electrode leading-out ESR value, good sealing performance, explosion-preventing function and simple and novel structure in production and manufacture of the super capacitors.
Description
Technical field
The utility model discloses one group of ultracapacitor overall package structure, belongs to the ultracapacitor technical field.
Background technology
Ultracapacitor is a kind of novel energy-storing device, have that the speed of discharging and recharging is fast, specific power is high, have extended cycle life, plurality of advantages such as serviceability temperature wide ranges, energy-conserving and environment-protective, be widely used in fields such as automobile, wind power generation, urban light rail, subway, solar energy, UPS and heavy industry equipment at present.
The electrode lead-out mode and the packaging effect of ultracapacitor are very big to the ultracapacitor Effect on Performance.If the electrode lead-out mode, especially the collector design is incorrect, will cause the ESR value of ultracapacitor very big, causes the ultracapacitor performance to meet the demands, and the effect in physical circuit reduces greatly, even causes and can't use.If seal bad, ultracapacitor in use, airborne moisture and oxygen enter into ultracapacitor, cause electrolytic conductivity to descend, the ultracapacitor internal resistance increases, and loses efficacy then, on the other hand, electrolyte also can be separated out along the bad place of sealing, and circuit board and other parts of circuit are caused corrosion.
Traditional super capacitor collection liquid body mostly is the metal of sheet and makes, and electrode is drawn difficulty, and technology difficulty is big, and often causes the requirement that is above standard of product E SR value, and simultaneously, traditional ultracapacitor liquid injection hole is not designed to have explosion prevention function to it.
Summary of the invention
The purpose of this utility model provides that one group of simple in structure, electrode draws that the ESR value is little, good seal performance, stable performance and have the ultracapacitor overall package structure of explosion prevention function.
The utility model for achieving the above object, the technical scheme of employing is ultracapacitor end cap, collector and cover plate deriving structure external member.Its innovative point is: package unit is simple in structure, and the cap liner that tight fit is installed in the liquid injection hole has explosion prevention function.
Described ultracapacitor end cap comprises cover plate, has electrode stomidium, liquid injection hole and welding bar on the cover plate, and insulation isolating seal circle is housed on the electrode stomidium, and the liquid injection hole tight fit is fitted with cap liner.Described cap liner material is a fine aluminium, has explosion prevention function, and when the ultracapacitor internal pressure increased to a certain degree, cap liner edge weld was torn, and cap liner generation self-disabling damages, and discharges the ultracapacitor internal pressure.
Fixture on the described ultracapacitor cover plate deriving structure is a regular hexagon, when being used for the ultracapacitor use, avoids the infringement to housing in the fixation procedure to ultracapacitor.
Adopt ultracapacitor overall package structure of the present utility model, because simple in structure, and be applied to ultracapacitor positive and negative electrode two ends port respectively, so ultracapacitor assembles easily, technology is simple.The ultracapacitor housing is not charged, the short circuit phenomenon that the prevention ultracapacitor causes because of the insulated hull breakage in installation and use.The collector assurance and the paper tinsel firm welding of dashing forward, welding ESR value is little, and the whole core bag of electrolyte rapid osmotic is simple in structure.Employing has the sealing of the cap liner of explosion prevention function as liquid injection hole, can guarantee that there is not the danger of blasting in ultracapacitor in abnormal conditions, is damaged by cap liner generation self-disabling, discharges the ultracapacitor internal pressure.
