  Super capacitor  is green energy (activated carbon), which does not pollute the environment.   2. Super capacitors have a long life (1-100,000 times); lead-acid batteries have a short life (500 times), are easy to damage and difficult to manage. They are 20-200 times longer than lead-acid batteries and can be the same fate as equipment.   The charging speed of super capacitors is fast (0.3 seconds to 15 minutes); the charging time of lead-acid batteries is long (5 to 8 hours). Many batteries have long charging time and a short driving distance.   The loading and discharging efficiency of ultra capacitor is high (98%) and that of lead-acid battery is low (70%).   The power density of super capacitors is high (10.000W/kg). While that of lead-acid batteries is low (300W/kg), which is more than 30 times worse.   Super capacitors are totally maintenance-free, operating temperature range (-40-50); lead-acid battery electric vehicle driving mileage at-40 C is reduced by 90%, and super capac

  Because super capacitor/ultra capacitor is a new type of product. Therefore, we have made different updates and adjustments in structure, material and performance. According to different content, we have different methods to classify Super capacitor/ultra capacitor. At present, the classification of super capacitor refers to the principle of capacitor, electrolyte and other two major elements. Each type of supercapacitor/ultra capacitor can be divided into different categories.   (1)Classification according to principle. According to different working principles, Super capacitor/ultra capacitor can be separated into two categories: double layer capacitor and pseudo capacitor/ultra capacitor. The electric double layer Super capacitor/ultra capacitor has been reprocessed on manufacturing materials, such as activated carbon electrode materials, electrodes made of activated carbon materials with high specific surface area, and carbon aerogel electrode materials, and gelatin is prepared b

  Super capacitor /ultra capacitor is a physical secondary power supply with super storage power and strong pulsating power. Super capacitor/ultra capacitor can be divided into three categories according to energy storage mechanism: (1) double layer capacitors produced by charge separation at the interface between carbon electrode and electrolyte; (2) Faraday capacitors produced by reversible chemical adsorption by oxidation-reduction reaction on the surface and bulk phase of electrodes using metal oxides as electrodes; (3) Faraday capacitors produced by reversible chemical adsorption on the surface and bulk phase of electrodes. A capacitor that undergoes redox reactions using conductive polymers as electrodes. Double capacitor is a new type of energy storage device which uses polarized electrolyte to store electric energy.   Because the charging and discharging of double-layer capacitors belong to the physical process, its cycle time is high and the charging process is fast, so it is

  The development of super capacitor/ultra capacitor is a revolution of energy storage equipment (batteries). Other energy storage devices are transformed from electrical energy to chemical energy, then from chemical energy to electrical energy. There is loss of energy in two transformations. Super capacitor/ultra capacitor charges directly, discharges directly, and the form of energy does not change. The charge and discharge efficiency is as high as 98%, and the economic value is high, only 70% of lead-acid batteries.   Ultracapacitor is a product that emerged in the late 1970s. It breaks through the traditional design idea of capacitor. The capacitor has been raised from micro-farad level to farad level (1 farad = 106 micro-farad), creating 1000 farad level Super capacitor/ultra capacitor; by the end of last century, 10,000-100,000 methods have appeared successively. Since then, the traction Super capacitor/ultra capacitor has entered the battery application market, and a new concept

  The scientific name of super capacitor is electronic double-layer capacitor. Unlike the traditional nano-dielectric capacitor with high capacitance value, the super capacitor does not use the traditional solid-state electrolyte. The energy density of super capacitors is higher than that of ordinary capacitors and smaller than that of lithium batteries. Its power density is lower than that of ordinary capacitors and larger than that of lithium batteries.   Super capacitor/ultra capacitor, also known as double layer capacitor, is a new type of energy storage device, which has the characteristics of a short charging time, long service life, good temperature characteristics, energy saving and green environmental protection.   The backup power supply of minute current supply for tax control computer, tax control refueling machine, vacuum switch, intelligent meter, remote meter reading system, instrument, digital camera, handheld computer, electronic door lock, program-controlled switch, c

  Compared with ordinary capacitors, Super capacitor/ ultra capacitor s  has been improved in structure and optimized in principle. But the function of super capacitor/ultra capacitor is similar to that of conventional capacitor during service. The functions of the new capacitor devices are mainly manifested in bypass, decoupling, energy storage and so on, which have obvious regulating and controlling effects on circuit operation or storage charge. Specific functions are as follows:   (1)By-pass. Bypass capacitors in Super capacitor/ultra capacitor can store electrical energy regularly, but other components can release charges in time to maintain their use when they need energy in operation. The maximum function of bypass capacitor is the balance of charge output of regulator, which avoids the circuit fault caused by the confusion of charge transmission. The device has strong flexibility in charging and discharging.   (2) Decoupling. Decoupling is mainly aimed at the phenomenon of &quo

  Any Super capacitor/ultra capacitor will discharge through an internal shunt resistance in the case of electrification. This discharge current is called leakage current, which affects the self-discharge of the Super capacitor/ultra capacitor unit. Similar to some secondary battery technologies, the voltage of Super capacitor/ultra capacitor also needs to be balanced when used in series, because the leakage current exists in the super capacitor, and the magnitude of the internal shunt resistance determines the voltage distribution on the series Super capacitor/ultra capacitor unit. When the voltage of ultracapacitor is stable, the voltage on each cell will change with the leakage current, not with the capacitance. The larger the leakage current, the smaller the rated voltage. On the contrary, the smaller the leakage current, the higher the rated voltage. This is because the leakage current will cause the discharge of Super capacitor/ultra capacitor cells and reduce the voltage, which
