An easy way to make high-performance micro-supercapacitors based on nanocrystal building blocks has been developed by scientists in the US and China. Micro-power sources have become a key component for micro-electronics but they are expensive and difficult to make. To demonstrate their concept, the team made nanoporous thin-film pseudocapacitor electrodes that showed ultrafast lithium storage kinetics, high capacitance and excellent cycling stability, giving them great promise for high energy and high power micro-device applications.
