Working characteristics: high temperature super capacitor is a capacitor based on double-layer principle. When the applied voltage is applied to the two plates of the high temperature super capacitor, the positive electrode of the high temperature super capacitor stores a positive charge, while the negative electrode stores negative charge. Under the electric field generated by the charge on the two plates of the high temperature super capacitor, the positive electrode forms on the interface between the electrolyte and the electrode. The opposite charge balances the internal electric field in the electrolyte. On the contact surface between two different phases, the positive charge and the negative charge are arranged in the opposite position by a very short gap between the positive charge and the negative charge. This charge distribution layer is called a double-layer, so the capacitance is very large. When the potential between the two plates is lower than the redox electrode potential of the electrolyte, the charge on the interface of the electrolyte will not detach from the electrolyte. The high temperature capacitors work normally (usually below 3V). If the voltage at both ends of the capacitor exceeds the redox electrode potential of the electrolyte, the electrolyte will be decomposed into an abnormal state. State. On the discharge of high temperature super capacitor, the charge on the positive and negative plates is released by the external circuit, and the charge response on the interface of the electrolyte decreases. It can be seen that the charging and discharging process of high temperature super capacitor is always a physical process without chemical reaction. Therefore, the performance is stable, which is different from that of batteries using chemical reactions.
High temperature super capacitor has the advantages of short charging time, long service life, good temperature physical properties, energy saving and environmental protection. High temperature super capacitor has a wide range of applications. At present, it is used primarily in five aspects, including tax control computer, digital camera, handheld computer and other micro-current power supply backup power supply.
Since the introduction of super capacitor, the global demand has expanded rapidly, and it has become a new bright spot in the field of chemical power. This breakthrough not only fundamentally changes the position of electric vehicles in transportation. But also improves the possibility of intermittent energy utilization, such as wind energy and solar energy, to meet people's energy needs and reduce dependence on oil. High temperature super capacitor has great application value and development potential in many fields, such as automobile, electric power, railway, communication, national defense, consumer electronic products, etc. It has been widely concerned by all countries in the world, and the industry prospects are promising.
