A team of researchers has developed a highly efficient super -condenser who overcomes traditional energy density restrictions by using carbon nanotubes and conductive polymers.
Super condensers have the ability to charge and deliver large amounts of energy quickly and they are resistant enough to survive millions of charging and discharge cycles without much degradation.
However, they have a smaller energy density than conventional batteries, which means that they are not useful for long periods of time without recharge. This has limited their use in practical applications, such as electric vehicles and drones, according to the National Research and Technology Council in a report shared by Techxplore.
Scott Donne, a supercolorizer and a battery -like researcher at the University of Newcastle in Australia, explained where the superconstructions are compared to other technologies.
“You have high -power capacitors but low energy; high energy combustion cells but low power; and batteries sitting in the middle – that’s why they are the most popular of the three,” Done told Chemistry World.
Now, researchers led by Dr. Bon-Cheol Ku and Dr. Seo Gün Kim of the Carbon Company Research Center at the Korean Institute of Science and Technology and Professor Yuang Piao of the National University of Seoul have found a way to improve the energy density and supply of new power.

The combination of high-conductive single-sided carbon nanotubes and polyanilin polymer has created a complex fiber structure that allows their new superconstructioner to store more energy, while releasing it at faster speed, the report is explained.
“This technology overcomes the disadvantages of super-condensers by using single-walled carbon nanotubes and conductive polymers,” says Dr. Bon -cheol Ku.
Tests show that it maintains a stable performance, even after 100,000 charging and dilution cycles, and that it is durable enough to function in high -voltage applications.
This opens the ability to use in electric vehicles where it can replace or complement existing lithium-ion batteries. The technology provides efficient energy supply, along with fast charging capabilities that could improve the overall range and performance of EV.

With increasing efficiency and efficiency, these new super -condensers could increase the attractiveness of EV and help to move the tide from alternatives that burn dirty fuels.
These composite fiber structures of CNT-Pani design also provide high mechanical flexibility, which means that they can be wound and folded according to the report.
In the study published in the Journal Composites Part B: Engineering and shared by Sciensedirect, the data shows that the cells maintain 100% detention, even after a folded 180 degrees.
This resistance has helped researchers create thin film structures that can further expand the use of the next -generation supercapacitor in electronics as wearing.
Adding low -cost polymers also helped them reduce production costs and create a plan for mass production in various applications, making the way to commercialization.
“We will continue to develop and industrialize carbon fiber with high performance based on carbon nanotubi,” said Dr. Bon-Cheol Ku.
