Description
The present invention relates to the electrochemistry storage device, particularly a kind of oxide and hydroxide with nickel is made anodal electrochemical super-capacitor and manufacture method thereof.
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.Electrochemical capacitor is to be used for providing bigger excitation energy for high-energy laser at first.The model electrochemical capacitor can also replace nickel-cadmium cell and the lithium battery uninterrupted power supply (ups) Unity as computer and communication system.Large-scale electrochemical capacitor is used for electric automobile provides heavy-current discharge under situations such as startup, braking, the high power that has effectively solved storage battery 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.Can separate matter at electrode-electric and form this diffuse double layer at the interface naturally 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 ", resulting device by popular being called of people " ultra-capacitor " or ultracapacitor ", 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 can afford.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, under relative abominable service conditions such as automobile starting, acceleration, climbing and braking, then capacitor is started working, 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 much worthwhile on cost.
At present technology is comparatively ripe is to be the electrochemical double layer capacitor (i.e. the positive and negative pole material of this capacitor all be made up of active carbon class material symmetry capacitor) of electrode material with the porous activated carbon, but studies have shown that, generally be difficult in practice reach according to the materials theory capacitance that calculates to the thickness of the mensuration of surface area and electrode couple layer, the surface area of material is big more, gap between the capacity of Theoretical Calculation and actual measurement is big more, because " micropore " that the surface of material with carbon element exists electrolyte to be difficult to flood, we can't utilize the surface area of active carbon fully.Therefore, it is little to improve the leeway of material capacitance by the surface area that improves material.Contact resistance between activated carbon granule has limited Electric double-layer capacitor with higher power output.The striving direction that promotes the development of electrochemical capacitor store energy should be placed on " pseudo-capacitance " that how to make full use of material, on the capacity characteristic that improves material significantly.
It is transition metal oxide class material such as ru oxide RuO that material people with higher faraday " pseudo-capacitance " study more
2XH
2O) etc., RuO
2XH
2Though O possesses gratifying capacity (hundreds of farad/gram active material), but its fancy price has limited its further business-like application, people also study other metal oxide such as nickel oxide, but the symmetry electric capacity operating potential narrow range that this material is formed, and final discharging voltage is when being zero volt, understanding some electric weight can't emit, thereby the energy density of electric capacity is relatively low.Therefore, up to the present, also lack electrochemical super-capacitor a kind of cheapness, superior performance, that can be applied to a plurality of fields on the market.
