Supercapacitor (SC) is an electrical energy storage device with high energy density (comparable with rechargeable batteries), very fast charging/discharging, and high durability (sustaining millions of charging/discharging cycles with apparent loss of their capacities). We aim at increasing the energy density of SC beyond 50 Wh/L, which will lead to a paradigm shift in electrical energy storage technologies.
We utilize highly nitrogen doped graphene material (SC-GN3) offering energy density up to 200 Wh/L at a power of2.6 kW/L, 170 Wh/L at 5.2 kW/L, and 143 Wh/L at 52 kW/L and oppening doors to such technologies.
Our international team is developing SC prototypes, which manufacturing adhere to industry standards of leading SC manufacturers.
However, the ever-increasing demand for energy storage devices with improved performance and stability in all the above-mentioned sectors as well as in transportation (electric vehicles), grid storage (large energy storage and power levelling), electronics in space applications (satellites, new missions), and implanted medical devices (e.g., implantable cardioverter defibrillators, pacemakers) is motivating the scientific community to develop new chemistries, compositions, and morphologies of electrode materials.
Currently, rechargeable lithium-ion batteries (LIBs)—the most widely used electrochemical energy storage system of today—are used only in a limited number of applications because of power densities and fire safety issues. For example, electric vehicles will benefit from energy storage devices with high charging/discharging rate capabilities (power density) for acceleration or for energy management (recharging during vehicle braking).
