Supercapacitor is a new energy storage device developed after 1980s. It has begun to form a new industry in Europe, the United States and Japan。

Since the 1990s, China has developed super electric double-layer capacitors, which still lags behind the advanced level of foreign countries. According to relevant data, some domestic units have developed high-energy supercapacitor samples with specific energy of 10wh / kg and specific power of 600W / kg and high-power supercapacitor samples with specific energy of 5wh / kg and specific power of 2500W / kg, with recycling times of more than 50000 times. The performance index has reached the international advanced level, the cost has decreased significantly compared with the international average price, and the application level is preliminarily met. We believe that with the encouragement of the spirit of innovation, China's super capacitors will soon catch up with and surpass the world's advanced level.
