Supercapacitor

Patent Wang, Donghai; Yi, Ran; Chen, Shuru

Embodiments provide a hybrid supercapacitor exhibiting high energy and power densities enabled by a high-performance lithium-alloy anode coupled with a porous carbon cathode in an electrolyte containing lithium salt. Embodiments include a size reduced silicon oxide anode, a boron-doped silicon oxide anode, and/or a carbon coated silicon oxide anode, which may improve cycling stability and rate performance. Further embodiments include a hybrid supercapacitor system using a Li-active anode in an electrolyte including LiPF6 in a mixture of ethylene carbonate, diethyl carbonate, and dimethyl carbonate (EC:DEC:DMC, 2:1:2 by vol.) and 10 wt % fluoroethylene carbonate (FEC), which may reduce the self-dischargemore » rate. « less

Supercapacitor with metal cyanometallate anode and carbonaceous cathode

Patent Lu, Yuhao; Wang, Long; Lee, Jong -Jan

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.sup.+) anions (B.sup.-), and a cathode including carbonaceous materials (.quadrature.). 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.
