Description
Technical field
The present invention relates to a kind of preparation method of high-voltage electrochemical capacitor, belong to the electrochemical capacitor field.
Background technology
Electrochemical capacitor has obtained people with its outstanding effect and advantage and has approved widely in electronics industry.Compare with traditional capacitor, electrochemical capacitor has high capacitance, limited frequency response, high equivalent series resistance (ESR), the electric capacity relevant with voltage and the relevant self discharge speed with voltage.Initial electrochemical capacitor is to provide bigger excitation energy for high-energy laser.And the model electrochemical capacitor can also replace nickel-cadmium cell and the lithium battery uninterrupted power supply (ups) Unity as computer and communication system now.Large-scale electrochemical capacitor is used on the electric automobile to provide heavy-current discharge under situations such as startup, braking, and the high power that has solved storage battery effectively discharges and recharges problem, has prolonged the working life of storage battery.Therefore, electrochemical capacitor has a wide range of applications at numerous areas.
Be different from traditional capacitor, the high power capacity of electrochemical capacitor forms by adopting the large tracts of land porous electrode and storing energy between the diffuse double layer.This bilayer can be separated matter at electrode-electric and form naturally at the interface when having voltage between the electrode, its thickness generally has only the diameter of a hydrone, has formed minimum effective " plate separation " thus.In addition, under many circumstances, energy stored increases by so-called " pseudo-capacitance " or " pseudocapacity " basically, and this kind effect also occurs in electrode-electric and separates matter at the interface.Electric double layer capacitance is generally 16-40 microfarad/square centimeter, and passes through the highest 100 microfarads/more than the square centimeter of can reaching of capacitance that " pseudo-capacitance " form.Adsorption desorption or fast electrochemical redox reaction (there is not tangible phase change in active material) take place near electrode place or its, and this capacitance can further increase.The capacitance of this increase is called " pseudo-capacitance ", and resulting device is by popular the becoming of people " ultra-capacitor " or " ultracapacitor ", and it is the pseudocapacity of reflection faraday signal, has the specific capacity higher than pure electric double layer capacitance.
Double layer capacitor is based on high surface area electrode material activity charcoal, and this kind material provides high surface A, and " effectively double-deck " thickness d is reduced to the atomic diameter scale, has therefore formed high capacitance.Beck has delivered the patent of first piece of relevant double electric layer capacitor early than the sixties.But the real rise of electrochemical capacitor research is to be widely used as the computer uninterrupted power supply and after the early 1990s, American National Ministry of Energy proposed electrochemical capacitor is applied to the huge plan of electric automobile at it.
The general stored energy of chemical power source equals to change relevant electric charge with electrochemical redox and multiply by potential difference between the battery electrode.Discharge and recharge the variation that often relates to the active material phase in the course of reaction.Thereby, although energy density is higher relatively, discharges and recharges reaction speed and compare relatively slow with electrochemical capacitor.Compare with battery, electrochemical capacitor have do not need repairing, longer cycle life, safe in utilization, do not have advantages such as memory effect.The more important thing is that electrochemical capacitor has the performance that the big electric current of high power that battery do not have discharges and recharges continuously, has promoted this class high power devices and Products Development.Therefore, electrochemical capacitor is a kind of extremely attractive energy storage device.
The energy storage system that is used for electric motor car requires to possess high energy density so that enough driving scopes to be provided.It must have higher power density to satisfy the acceleration performance demands of electric automobile.It must have sufficiently long discharge and recharge the life-span and also must have the user the price that rises that can bear.The plurality of advantages of electrochemical capacitor energy storage system makes it have the potentiality of application in fields such as electric vehicle power sources.Electrochemical capacitor is necessary in the hybrid electric vehicle composite power source, electrochemical capacitor can be provided for electric automobile and quicken fast, the power increment that the heavy load operation is required can't this maximum commercialization technical barrier of high power discharge thereby solved batteries of electric automobile.Battery and electric capacity form parallel circuits, when automobile overflows row still by the battery normal power supply, start working at next capacitors of relative abominable service condition such as automobile starting, acceleration, climbing and brakings, the use of capacitor has effectively solved the heavy-current discharge problem of battery, and compares a kind of battery with effect of the same race of design and want worthwhile many on cost.
Traditional electrochemical capacitor generally adopts stainless steel column type outer cover packaging, the inner rich formula structure of volume that adopts.Or adopting the square outer cover packaging of stainless steel, laminated structure is adopted in inside.Above-mentioned two types electrochemical capacitor can only provide the operating voltage (use organic bath) of maximum 2.5V, as adopt a plurality of such monomer series-connected modes will occupy bigger volume, cause the volume and capacity ratio of capacitor to reduce, significantly increase the equivalent series resistance (ESR) of capacitor simultaneously, can't effectively satisfy the requirement that high-power discharges and recharges.
