New 3D-Printed Graphene Aerogel For Better Energy Storage
Researchers at Lawrence Livermore National Laboratory in California have developed a new type of graphene aerogel using a 3D printing technique. Microlattices were created with an engineered support system of the 3D technique known as direct ink writing.
Benefits to this aerogel include high surface area, excellent electrical conductivity, its lightweight property, mechanical stiffness and supercompressibility (up to 90 % compressive strain).
Aerogel, also known as “liquid smoke”, is a synthetic porous material that is a derivative of gel. Instead of the usual liquid portion in gel, a gas replaces it, resulting in an extremely low-density solid that has low thermal conductivity.
Apart from better energy storage, graphene aerogel can be used in sensors, nanoelectrics, catalysis and separations.
