Supercapacitor, also known as electric double layer capacitor, is a new type of electronic component that appeared in the late 1970s. It is different from the concept of placing a medium between two plates to form a traditional capacitor. Its principle is to use ions on the two-phase interface. Electric double layer charge storage produces farad-level ultra-large capacity. Its working principle is shown in the figure below:
In reent years, the development of supercapacitors has gradually entered a mature stage, making them increasingly widely used in home appliances, computers, automobiles, automatic control, aerospace and other fields. However, selecting appropriate electrode materials is an important prerequisite for the large-scale application of supercapacitor technology. The YEC®-8 series supercapacitor activated carbon developed by our company still has good electrochemical properties while maintaining high specific surface area and high specific capacitance. Compared with similar foreign products, it has a higher cost performance and has been practically used in supercapacitor manufacturers at home and abroad.
Features:
Extensive surface area
Activated carbon with very fine pores can store and discharge electrons and ions instantaneously. Shows superior results in the periodic life test.
High-quality management
Trace metals contained in the high activation products are refined to a high level to increase purity.
Excellent electrochemical properties
