  • 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 recent 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®-200D 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.

    •  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


    BET Surface area(m2/g)


    Bulk density(g/ml)






    Capacitance with PC (F/g)


    Particle size(D50, µm )



    1、Lower resistance compared to similar products;

    2、Good rate characteristics, with a discharge capacity retention rate of over 93.5% at a current density of 50A/g.
