Recently, reporters learned from the Shanghai Institute of Ceramics, Chinese Academy of Sciences, that scientist Huang Fuqiang and his team have developed a high-performance electrode material for supercapacitors. —— Nitrogen-doped ordered mesoporous graphene. This material exhibits outstanding electrochemical energy storage properties and can be used in electric vehicles. “ Ultra-high-capacity battery ” : Charging takes only 7 Seconds to keep going. 35 kilometer. The relevant research findings have been published in... 12 Moon 18 It was published in the world's top journal, "Science."
Supercapacitors are electrochemical energy storage devices that lie between conventional capacitors and batteries. Thanks to their high power density, long cycle life, and high safety and reliability, they are now widely used in various fields, including hybrid electric vehicles and high-power output equipment. For a long time, scientists have been unable to find an ideal material that would enable supercapacitors to simultaneously achieve both high power and high energy storage.
To tackle this challenging problem, the Shanghai Institute of Ceramics of the Chinese Academy of Sciences, in collaboration with Peking University and the University of Pennsylvania in the United States, has been conducting ongoing research. Ultimately, Huang Fuqiang’s research team discovered that graphene is the optimal choice for supercapacitor electrodes.
Through repeated experimentation, design, and synthesis, Huang Fuqiang’s research team found that nitrogen-doped ordered mesoporous graphene exhibits the best performance. Not only does it achieve high energy density and high power density, but it also uses water-based electrolytes, making it non-toxic, environmentally friendly, inexpensive, and safe and reliable.
According to the introduction, this new graphene supercapacitor is lightweight, non-flammable and non-explosive, and can be manufactured at low cost, enabling large-scale production. Thanks to its significant competitive advantages over batteries such as lead-acid and nickel-hydrogen, and its markedly superior performance in rapid charging and discharging compared to lithium batteries, this... “ Super battery ” It can be widely applied to the upgrade and replacement of existing hybrid electric vehicles and high-power output devices.
