From their initial observation by General Electric engineers and subsequently commercialization by Standard Oil, ultracapacitors have grown into a multi-million industry. With their green energy properties, which include quick charging and temperature stability, these battery alternatives have high potential to replace the conventional batteries found in electric cars and their hybrid cousins.
New Development
On a new development, researchers at the University of Texas have developed graphene to boost the energy storage capacity of ultracapacitors. Supposedly, the carbon-based nanomaterial will double the present maximum capacity of these battery alternatives.
Graphene is described as a planar sheet of carbon atoms, which are one-atom thick and densely condensed in a benzene ring structure. When you see images of graphene, you will think of chicken wire or a honeycomb lattice albeit in atom sizes.
The ability of graphene to store large amounts of energy lies in its large size, atomically speaking. With each gram of graphene equivalent to one large football field, it is no wonder that the potential for double amounts of stored energy is possible. It will take more research on the matter but it is an exciting development, nonetheless.
