Product Sector: Energy → Energy Storage → Electrical Energy → Supercapacitor
High fuel prices and global climate change are creating a societal need for renewable and sustainable energy. As an energy storage option, ultracapacitors offer significant advantages over batteries. However, current ultracapacitor technology does not lend itself to widespread market integration due to limited storage capacity and high production costs.
Nanospring technology from GoNano solves these problems by offering a 100% accessible surface area, higher energy density and lower costs than activated carbon electrodes.
GoNano Technologies Nanospring Electrodes offer a 100% accessible surface area. With the addition of advanced coatings, they achieve a new level of performance compared to standard activated carbon electrodes. Nanospring Electrodes produce higher energy density at a lower cost.
Image (a) to the left shows the morphology of an individual Nanospring viewed using a transmission electron microscope (TEM). At high resolution, the amorphous nature of the Nanosprings is evident. A Nanospring mat (b) is shown in the scanning electron microscope (SEM) image.
Nanospring electrodes are extremely durable and are capable of withstanding radial stress. This robustness allows post growth processing, shaping, and forming.
The open nature of the Nanospring electrodes allows full access to the entire surface area. Consequently, for ultracapacitor applications electrolytes with larger ions can be utilized. This enables devices with superior energy densities at a higher voltage.
