A research group of the NIMS International Center for Materials Nanoarchitectonics (MANA) succeeded for the first time in making products with a structure where ultrathin graphene is glued to a 3D strutted framework. This was achieved by a novel and unique method inspired by the blown sugar art also called the "chemical blowing method."
Electrochemical capacitors with electrodes made of the strutted 3D graphene products can achieve a high specific power density. The new products are expected to be widely used as high-performance capacitor materials in devices for fast charging and discharging of portable electronics and electric vehicles and electromagnetic launching of aircrafts. The "chemical blowing method" will also be widely available as a novel method for making ultrathin membranes more than graphenes.(...)
