Global Supercapacitor Size

The U.S. National Energy Administration predicts that the size of supercapacitors in the global market is expected to grow from 4 billion U.S. dollars in 2007 to 12 billion U.S. dollars in 2013 (about 73.1 billion yuan), and supercapacitors made of graphene as electrodes will be The performance has greatly improved. This reporter learned at the annual meeting of the 2013 Plastics New Materials, New Technologies, and New Achievements Exchange held in Qingdao in the end of October and the China Plastics Association Expert Committee.

According to experts, in 2007, U.S. authoritative magazine listed super capacitors as one of the top ten technological discoveries in the world in 2006, arguing that super capacitors are a revolutionary development in the field of energy storage. Activated carbon, activated carbon fiber and other carbon materials are the most widely studied and used supercapacitor materials. Since the successful preparation of graphene, the industry has actively explored the application of this new carbonaceous material in supercapacitors. Graphene has a very high specific surface area, both sides of the graphene sheet can be charged to form a double electric layer, in addition to graphene folds and superimposed effect, can form nanoholes and nanoholes, conducive to the diffusion of the electrolyte, so Graphene-based supercapacitors have good power characteristics.

Experts point out that graphene-based materials have shown great potential for application in supercapacitors based on graphene's many excellent properties, such as its ultra-high conductivity and its large surface area. The supercapacitors made of graphene as electrodes will greatly improve the performance. In the future, with the gradual promotion of supercapacitors, graphene will also face a huge market space.

It is understood that graphene can be used in many fields such as electronics, aerospace, optics, energy storage, biomedicine, and daily life. In the wire and cable industry, conductive performance is a key to measuring the quality of wire and cable, and graphene has excellent electrical conductivity. Therefore, applying it to cable conductors to increase the conductivity of cables is also a major direction for future research. There are wire and cable companies to study this.
