A sustainable, powerful micro-supercapacitor may be on the horizon, thanks to an international collaboration of researchers from Penn State and the University of Electronic Science and Technology of China. Until now, the high-capacity, fast-charging energy storage devices have been limited by the composition of their electrodes the connections responsible for managing the flow of electrons during charging and dispensing energy. Now, researchers have developed a better material to improve connectivity while maintaining recyclability and low cost.
Inexpensive tin packs a big punch for the future of supercapacitors

“The supercapacitor is a very powerful, energy-dense device with a fast-charging rate, in contrast to the typical battery but can we make it more powerful, faster and with a really high retention cycle?” asked Jia Zhu, corresponding author and doctoral student conducting research in the laboratory of Huanyu “Larry” Cheng, Dorothy Quiggle Career Development Profe
