While the supercapacitor developed by the team has a comparable energy density to state-of-the-art value of lead-acid batteries, its power density is two orders of magnitude higher at over 10,000 Watt per litre.

Design teams are now eyeing supercapacitors for a range of new products in energy harvesting, office automation, backup systems, and more. These supercapacitor cells provide efficient storage that can quickly discharge energy on demand. To ensure peak performance and a long product life cycle, the supercapacitor’s voltage must be balanced. If an imbalance occurs due to leakage current differences between the cells, an energy drain could be triggered, causing the supercapacitor cells to fail prematurely.

CAP-XX (LSE: CPX), a leader in supercapacitors that deliver peak power to support or replace batteries, today announced it has developed the industry’s first 3V thin, prismatic supercapacitors. The company will deploy its 3V technology first in the thin prismatic form to meet the demand for small, inexpensive, energy-efficient power solutions for thin wearables, key FOBs and other IoT devices. CAP-XX will then integrate the 3V technology into its larger prismatic supercapacitors, automotive modules, and other products for high-energy, high-power applications.

Scientists from Skoltech, Moscow State University (MSU) and Moscow Institute of Physics and Technology (MIPT) have proposed a new approach to replacing carbon atoms with nitrogen atoms in the supercapacitor’s crystal lattice and developed a novel capacity enhancement method based on carbon lattice modification with the aid of plasma. Their findings can help create the next generation of power sources for portable electronics. The results of their study were published in Nature – Scientific Reports.
