Abstract
A method is provided for charging a supercapacitor. The method initially provides a supercapacitor with a metal cyanometallate (MCM) particle anode, an electrolyte including a salt (DB) made up of cations (D+) anions (B−), and a cathode including carbonaceous materials (□). The method connects an external charging device between the anode and cathode, and the charging device supplies electrons to the anode and accepting electrons from the cathode. In response to the charging device, cations are inserted into the anode while anions are absorbed on the surface of the cathode. A supercapacitor device is also presented.
