Polyaniline (PANI) is one of the most attractive tantalum capacitor materials. In order to enhance electrolyte diffusion and improve the electrochemical performance of the electrode, a well-designed PANI morphology is required. The incorporation of carbon materials is also beneficial to improve the

The Zhongshuai Wu team of the Dalian Institute of Chemical Physics of the Chinese Academy of Sciences collaborated with Klaus Müllen of the German Max Planck Polymer Research Institute and Xinliang Feng of the Dresden University of Technology to develop a high-efficiency fluorine-doped graphene by e

A bus can be fully charged in one minute, and can drive for 6 kilometers after each charge. As a kind of energy storage device with special performance between traditional capacitor and battery, it has short charging and discharging time and cycle life. Long, repeated charge and discharge hundreds o

With the development of renewable energy power generation technology, microgrids capable of integrating distributed power sources are an effective way to meet increasing power demand, save investment and improve energy efficiency. As an energy buffering part of the microgrid, the energy storage syst

SMM Reuters: Chemists at the Lomonosov Moscow State University in Moscow recently synthesized a special type of graphene nanoparticle that resembles jellyfish and modified it. The structure of these particles allows them to be used in catalytic processes and in the manufacture of conductive polymers

Fast, portable, ultra-cyclable capacitors are no longer difficult to find. Researchers at the University of Central Florida (UCF) used the new R&D process to complete the "system upgrade" of supercapacitors: they quickly recharged their phones in a matter of seconds. The technological innovation of

When charging a supercapacitor for a backup power system such as a solid state drive (SSD) or a portable medical system, the value, size, and cost of the supercapacitor are directly proportional to the required hold time. Once the user removes the system from the input power and the operation is swi
