We are the earliest institution that do research on graphene and sell scientific products in China. The team has launched the fundamental scientific research, preparation and development of applications on graphene since 2007. At present, we have mastered some key technologies (such as preparation of high quality of graphene in large scale, self-assembling of graphene oxide membrane at liquid/air interface, 3D hierarchical porous graphene, and multiple hybridized composite) and obtained significant developments in graphene-based energy storage material with high power and specific capacity.
