'Ice-fire' forge crafts wafer-scale energy storage capacitors in just one second

A research team led by Prof. Hu Weijin from the Institute of Metal Research (IMR) of the Chinese Academy of Sciences (CAS), in collaboration with partners, has developed a one-second fabrication method for wafer-scale energy storage capacitors that achieves astonishing heating and cooling rates of up to 1,000°C per second.

Supercapacitors: China cuts production time from hours to one second. Huge industrial implications. - Economic Scenarios

A breakthrough in the manufacturing of dielectric capacitors promises to reduce costs and dramatically improve efficiency. From deep space to directed-energy weapons, here's how Beijing is changing the rules of the game. There's a critical component, often overlooked by the general public but essential for heavy industry and power electronics: the dielectric energy storage capacitor. These devices are the "work mules" of electronics: they must c…
