Abstract
The invention provides a super capacitor of a flexible package water system. The super capacitor is characterized in that a polyethylene film, a polypropylene film, an aluminum-plastic film and other packaging films are taken as shells; the packaging films can be cut into any shaped packaging films as needed; the any shaped package films are subjected to heat seal to obtain good sealing effect. The upper part of the super capacitor is provided with an exhaust pipe which is used for discharging gas generated by using the super capacitor for a long time; meanwhile, the upper part of the exhaust pipe is filled with polytetrafluoroethylene filtrate sheets, so that leakage can be effectively prevented. Due to adoption of the flexible package, the super capacitor is low in cost, is not restricted by common shell sizes, is simple in production process, light in product quality and small in volume, and is convenient to freely assemble; and in addition, the power-to-weight ratio of the super capacitor is large. The novel flexible package and an exhaust pipe structure are adopted for the super capacitor, thus effectively solving the problem of shell package for super capacitors of existing water systems.
Description
Technical field
The present invention relates to a kind of flexible package aqueous super capacitor, belong to the ultracapacitor technical field.
Background technology
Ultracapacitor is a kind of novel energy-storing product between physics electric capacity and chemical power source that development in recent years is got up, and its memory capacity is than big several orders of magnitude of ordinary capacitor, cycle life be the general chemistry power supply tens to hundred times.Ultracapacitor strengthens the area of two-plate by using the porous activated carbon material, thereby energy storage capacity is improved.Ultracapacitor has the big advantage of conventional capacitor power density, can discharge and recharge fast and efficiently.Chemical reaction does not take place in the activated carbon surface of high-specific surface area in its Charge Storage, has outstanding advantages such as long-life, high-power, non-maintaining, environmental protection.
Ultracapacitor can be divided into according to employed electrolyte and adopt acetonitrile, Merlon etc. as the organic ultracapacitor of electrolyte solvent with adopt the aqueous super capacitor two big classes of water as electrolyte solvent.The organic ultracapacitor monomer voltage is higher generally at 2.5V～2.7V, but the product energy storage is lower, generally is no more than 3000F.The organic ultracapacitor shell adopts box hat, aluminum hull etc. more, because it adopts the electrolyte and the technology of similar lithium battery, makes it also can adopt the aluminum plastic film soft package structure.
The aqueous super capacitor monomer voltage is generally at 1.4V～1.7V, but the product energy storage is higher, generally can accomplish more than the 80000F.Aqueous super capacitor electrolyte mostly is the aqueous solution of acid, alkali, has certain corrosivity, at present shells such as box hat or plastic housing that adopt more.Aqueous super capacitor because the decomposition of water can produce a small amount of gas, cause housing to expand, thereby common organic ultracapacitor flexible package mode can't be applied on the aqueous super capacitor after long-term the use simultaneously.Housing such as box hat or plastic housing is thicker, needs to adopt methods such as glue envelope, laser welding to seal in production operation, and the complex process cost is higher; Thicker thickness and the volume that has increased ultracapacitor and super capacitor module of while housing.
Summary of the invention
It is thick partially to the objective of the invention is the metal, the plastic casing that are adopted at existing aqueous super capacitor, production process complexity, housing are harder, shortcomings such as the product weight volume is big provide that a kind of Production and Packaging technology is simple, corrosion-resistant, thin thickness, flexible package aqueous super capacitor easy to use.
Technical scheme of the present invention is: the flexible package aqueous super capacitor, comprise shell, electrolyte, positive and negative plate, positive and negative lug, its improvements are that described shell is a flexible packaging film, flexible packaging film is polyethylene film, polypropylene film or aluminum plastic film, described positive and negative lug is the corrosion resistant metal band, described ultracapacitor top is provided with blast pipe, and the filtrate sheet is equipped with in the blast pipe upper end.
Described corrosion resistant metal band is pure nickel band, stainless steel band or nickel plated steel strip; Described flexible packaging film thickness is 0.1～1.0mm; Described filtrate sheet is the porous Teflon plastic sheet.
The present invention adopts polyethylene film, polypropylene screen or aluminum plastic film to replace common box hat, plastic housing, and the packaging film quality is pliable and tough, and can be cut into arbitrary shape on demand, after simple heat-sealing, can obtain good sealing effectiveness.
It is lead-out terminal as the both positive and negative polarity lug of ultracapacitor that this flexible package formula aqueous super capacitor adopts pure nickel band, stainless steel band or nickel plated steel strip, has good decay resistance for electrolyte such as potassium hydroxide.Its laminated structure is convenient to the connection in series-parallel combination between the ultracapacitor simultaneously, and it is little to adopt spot welding machine welding back to connect resistance.
The blast pipe that is provided with on the top of ultracapacitor, the gas that uses the back to produce for a long time can be discharged, at the filtrate sheet of blast pipe top filling, the polytetrafluoroethylstephanoporate stephanoporate structure of its existence makes gas to discharge simultaneously, but electrolyte can't pass through, and has effectively prevented the phenomenon of leakage.
The present invention also have the flexible package cost low, be not subjected to the restriction of common shell dimension, advantage such as production process is simple, small product size is little, independent assortment is convenient.Adopt novel flexible packing and exhaust pipe structure to efficiently solve the problem that aqueous super capacitor can't adopt the flexible package mode.
Description of drawings
Accompanying drawing is a flexible package aqueous super capacitor structural representation.
Embodiment
The invention will be further described below in conjunction with drawings and Examples.
At first adopt usual manner to manufacture ultracapacitor anode pole piece 3, cathode pole piece 4, and on pole piece, weld positive pole ear 1, the negative lug 2 of nickel plated steel strip material respectively, anode pole piece 3, the cathode pole piece 4 of soldering polar ear are superposeed successively, and between both positive and negative polarity, separate with barrier film 8.Subsequently with flexible packaging film 5 jacketed electrodes of polyethylene film, polypropylene screen or aluminum plastic film material, and put into the blast pipe 7 of polyethylene or polypropylene material, with heat sealing machine with involution around the flexible packaging film 5.
In ultracapacitor, inject the 6mol/L potassium hydroxide electrolyte by blast pipe 7, subsequently polytetrafluoroethylene filtrate sheet 6 is inserted blast pipe 7 upper ends, soak the back ultracapacitor is changed into, finish flexible package formula aqueous super capacitor and make.
With the 6000F flexible package formula aqueous super capacitor made is example, and capacity is not compared with the common housing ultracapacitor that adopts identical pole piece to make and changed, but product quality is reduced to 500g by the 610g that adopts box hat, and the product quality specific energy improves 22%.With the 5A electric current ultracapacitor charging was carried out overcharge test in 1 hour, can find that a small amount of gas emits from blast pipe 7, ultracapacitor does not have bulging, the phenomenon of leakage.
The part that the present invention does not relate to prior art that maybe can adopt all same as the prior art is realized.
