The graphene prepared by white has a high monolayer rate (up to 99%), fewer defects, and can be dried for a long time. Can be prepared into a variety of solutions to facilitate compounding with other materials. Raw material is natural graphite from a wide range of sources, is prepared by industrial methods can be scaled up production. To make the industrial application of graphene possible, promote the advancement of high-tech materials, and promote industrial development. granular activated charcoal
Chapter 3 Graphene-modified activated carbon for supercapacitor has good technical performance:Long cycle life, graphene modified ultracapacitors mountain in its storage process does not produce chemical reaction, the energy storage process is reversible, no “memory effect”, can be repeated charge and discharge hundreds of thousands of times, 500 times that of corrosion ion batteries, nickel-metal hydride and nickel cadmium battery is 1000 times, if the ultracapacitors charge-discharge 20 times a day, continuous use of up to 68 years:coal activated carbon supplier
High efficiency: super current discharge capacity, high energy conversion efficiency, small process loss, high current energy cycle efficiency ≥90%.
