New materials increase the capacity of supercapacitors by 5-10 times
Electric bus buses opened in cities, backup power used by base stations, and large-scale power stations, military equipment such as tanks and armored vehicles are all inseparable from supercapacitors. Xia Hui, a research scientist at the Institute of Light Science and Technology at Nanjing University of Science and Technology, has found a new material that can increase the capacity of supercapacitors by 5-10 times. The research results recently published in the top journals "advanced materials."
Compared to conventional capacitors and lithium batteries, this new, highly efficient energy storage material charges at high currents in just tens of seconds and has a longer life. Xia Hui said that currently on the market, the commercial use of supercapacitors more activated carbon electrode materials, the energy storage rate is limited. High-end supercapacitors on the market have only 1/12 of the lithium battery capacity per kg, which limits the widespread use of supercapacitors.
Xia Hui task force in a synthetic metal phosphide failed experiment, accidentally found an interesting method of modification, thereby increasing the capacity of the supercapacitor. This research will open a new opportunity for the wide application of supercapacitors. "Super capacitor capacity will be 5-10 times higher than the traditional activated carbon capacitor material, so the use of time can be extended to now 5-10 times." Xia Hui said the new material can be used two or three years after the electric bus and other electronic Products, the cost will be further reduced than the current price of capacitor products.
